HBMS8SS
Lighting Integrator BMS Interface Module
Installation and Setup
The Building Management System Interface Module
(HBMS8SS) provides an intelligent interface to other
building systems, such as HVAC or Security.
The HBMS8SS (BMS Interface Module) is used
instead of a Network Clock (HCLK8SS) to provide
smart control scenarios for up to eight global lighting
groups (channels) in the Lighting Integrator (LI)
network.
Instead of scheduling channels itself (like the
HCLK8SS), the BMS Interface accepts input from
an external system to signal whether that group is
Occupied or Unoccupied. For example, in some retail
applications, it may be more convenient to turn on
lighting when the security system is disabled just as
staff arrives. From a simple contact closure, the BMS
Interface automatically applies the proven control
scenarios selected during setup.
FEATURES
• Eight automation channels
• Up to four user-selectable control scenarios
• 2-line, 16-character display
• Menu-driven data entry
• Easily configured contact closure inputs and status
feedback
• Blink warnings and individual timed overrides
• Optional egress delay
• Automatically interfaces with Photocell Control
Module (HPCU8SS)
Before proceeding, read the instructions on the
following pages. For an overview of the entire system
and the documentation forms, refer to the other
sections of the LIGHTING INTEGRATOR INSTALLATION
AND OPERATION MANUAL.

HBMS8SS Building Management System Interface Module — Installation and Setup
OPERATION
In a Lighting Integrator system, relays
and their lighting loads may be
“smartwired” — or grouped for common
control — to one of eight channels in the
relay panel, or to the button of a dataline
switch. When there is no automation
module (either a Network Clock or BMS
Interface Module) in the network, relays
may be controlled manually by a wall
switch, automatically by a sensor, or by
an interface to some other system.
When the BMS Interface Module (or
Network Clock*) is added to the system,
the eight channels A-H have the capability
to become “global” — or system-wide
— automation groups. Relays grouped
to Channel A in Panel 01, and relays
grouped to Channel A in Panel 02, can be
controlled as a single global group.
An automation “scenario” can be
assigned to any channel. To choose a
scenario, ask the following questions:
• Is it an interior or exterior space?
• Do occupants turn lights on, or should
lights turn on automatically?
• Do occupants need to be warned when
lights are about to turn off?
• Should exterior light stays on all night,
or turn off after the building is closed?
On the HBMS8SS, each channel has
its own connection to an external
source — such as the HVAC system,
security system, or some other source
of scheduling input — with both input
contacts and status feedback contacts.
The input contacts are user-definable, and
through a simple contact closure provide
“Occupied” or “Unoccupied” status to
the BMS Interface Module. With this
information, the HBMS8SS will control
the lighting based on the smart scenarios
selected by the user.
Since there are a total of eight global
channels, careful thought must be given
to which groups of relays share common
scheduling and automation scenarios.
* Only one Network Clock or BMS
Interface Module can be used in a single
Lighting Integrator network to provide
smart control scenarios. If the HBMS8SS
module is the primary controller, an
HCLK8SS Clock Module should not be
connected to the dataline, but may be
used in Programming mode to program
dataline switches.
AUTOMATION SCENARIOS
Each channel may be assigned any one
of four different automation scenarios as
follows:
Interior Lighting
Scenario 1:
Scheduled ON/OFF
(Interior Lighting)
Relays smartwired to channels assigned
this scenario will turn on whenever
the channel’s input contact signals.
“Occupied", and off when it signals
“Unoccupied.” As an option, the lights
will blink to alert occupants five minutes
before the lights turn off. Any HDLS
series dataline switch button controlling
affected relays will also begin to flash.
Pressing the switch button will stop the
flashing and start a timed delay for that
relay, overriding the off command.
An egress delay up to 4 hours may also
be set for the channel.
Data required by the BMS Interface
Module:
A Override time delay (in 10-minute
increments, up to 4 hours)
B Blink Warn? Yes/No
C Egress Time (in 10-minute increments,
up to 4 hours)
D Define “Occupied” for Input Contact
(Occupied = Open or Closed contact)
E Define Status Contact (Closed contact
= Any ON, All ON, All OFF, Any OFF)
Scenario 2:
Manual ON/Scheduled OFF
(Interior Lighting – Alternate)
Relays smartwired to channels assigned
this scenario will not turn on until turned
on by an occupant, even if the channel’s
input contact signals “Occupied.” During
"Unoccupied" periods, this scenario acts
the same as Scenario 1 and requires the
same data input.
Exterior Lighting
The following two scenarios for exterior
lighting appear automatically as menu
selections in the HBMS8SS when an
HPCU8SS Photocell Control Module is
connected to the system. Programming
scenarios for the channels is still done
through the HBMS8SS.
The Photocell Control Module receives
actual light level data from the HPSA
Photocell Sensor mounted on the
building’s roof and wired to the HPCU8SS.
(For testing, a simulated light level
function is available.)
For details on the Photocell Control
Module, refer to the installation
instructions HPCU8.
Scenario 3:
Dark ON/OFF
(Exterior Lighting – Security)
Relays smartwired to channels assigned
this scenario will turn on when it is
dark outside and turn off when it is
light. “Dark” is defined by the user in
footcandles. Typical settings for security
lighting are from 2 to 20 fc.
Data required by the BMS Interface
Module:
A Define “Dark” from 2 to 200 fc
B Define Status Contact (Closed contact
= Any ON, All ON, All OFF, Any OFF)
Scenario 4:
Dark ON/Scheduled OFF
(Exterior Lighting – Parking Lots,
Signs)
Typical settings for Parking Lot lighting
are from 2 to 20 fc, and for Signage, 20 to
200 fc. Egress Time is the delay between
the Unoccupied signal and the time the
lights should actually turn off. It is used
to allow safe exit for the last building
occupants.
Data required by the BMS Interface
Module:
A Egress Time (in 10-minute increments
up to 4 hours)
B Define “Dark” from 2 to 200 fc
C Define “Occupied” for Input Contact
(Occupied = Open or Closed contact)
D Define Status Contact (Closed contact
= Any ON, All ON, All OFF, Any OFF)

SAMPLE LIGHTING
INTEGRATOR APPLICATION
To illustrate how to program the BMS
Interface Module, we will use the two-
story office building application shown in
Figure 1.
There is one panel per floor, and each
panel contains 16 relays controlling open
office space and 4 relays controlling
hallways and common areas. There are
also 4 relays for exterior security lighting,
and 6 for parking lot lighting and signage
in panel 01. The sample documentation
forms on page 4 summarize the data
entry required by the BMS Interface
Module and indicate how relays are
associated with channels.
Channel A is assigned a Manual
ON/Scheduled OFF scenario for
open office areas. In these areas, lights
will be turned on by occupants upon
Channel D is assigned a Dark
ON/Scheduled OFF scenario
for parking lot lighting and signage.
Non-security exterior lighting depends
on actual light levels outside, as well
as building occupancy. The lights will
turn ON when it is dark if the building
is occupied, and will turn OFF when it
is light, or when the building becomes
unoccupied. A 1-hour egress delay
allows safe exit for building occupants.
In some applications, such as a retail
store, signage may be turned off when
the store closes, well-before parking lot
lighting turns off. In this case, parking
and signage should be assigned to
separate channels (for example: D
and E) to allow for different treatment.
arrival, and off when the channel goes
“Unoccupied”. A 2-hour timed override
will be in effect during unoccupied times.
Channel B is assigned a Scheduled
ON/Scheduled OFF scenario for
hallways and common areas. In these
areas, lighting will be turned on and off
based on the occupied/unoccupied input
to the channel. A 2-hour timed override
will be in effect during unoccupied times.
Channel C is assigned a Dark ON/
OFF scenario for exterior security
lighting. This lighting depends only on
actual light levels outside, as measured
by the Photocell Sensor and sent through
the Photocell Control Module. Lighting
will turn ON when it is dark and OFF
when it is light outside, regardless of
building occupancy.

DOCUMENTING AUTOMATION
SCENARIOS AND RELAYS
Before proceeding with any smartwiring
or programming, it is necessary to
complete system documentation.
First, complete the BMS Interface
Module Automation Scenarios form,
recording which scenario will be assigned
to each channel (Figure 2).
Then, record the relays in each panel to
be associated with those channels on
the Relay Schedule form (Figure 3). A
relay should only be associated with one
automation channel.
Both forms are in the Documentation
section of the Lighting Integrator panel
Installation and Operation Manual.

Step 3:
Smartwire Each Relay
to its Associated Channel
If this has not already been done during
installation of the relay panels, smartwire
relays to their associated channels as
shown in Figure 5, referring to the Relay
Schedule form as shown in Figure 3.
HBMS8SS Building Management System Interface Module — Installation and Setup
INSTALLATION AND
SMARTWIRING
When both the BMS Interface Module
Automation Scenarios form and the
Relay Schedule form are complete, begin
the HBMS8SS installation as follows.
Step 1:
Install the BMS Interface Module
The HBMS8SS snaps onto the DIN rail
in any LI relay panel. (There is a release
clip on the bottom of the module.) Identify
the panel where the inputs from other
systems will be connected, and snap the
BMS Interface Module onto its DIN rail.
Step 2:
Wire the Input and Status Contacts
for Each Channel
See Figure 4.
Input Contacts: Red/White 2-wire
maintained dry contact input
Status Contacts: Yellow/Yellow
Ratings: 1 Amp, 24 VAC
Note: Default settings for the scenario
(Scheduled ON/OFF) and Input Contact
(Closed = Occupied) may cause the
system to respond when the input contact
is connected.
Figure 5 – Smartwiring Relays to Channels
1 Press and hold the Channel Push Button for several seconds. The red
channel LED will begin to flash. If any relays are currently controlled by that
channel, their LEDs will begin to flash as well.
2 Select the relays to be controlled. The LED for each relay “smartwired” to
the channel input selected will be flashing on/off. Press the associated Relay
Control Button to add/delete that relay to/from the group.
3 Press the Channel Push Button again. The LEDs will stop flashing and the
channel will now control the relays selected.
Test by pressing the Channel Push Button to toggle the group on/off/on. The
channel LED will track the last action. Now turn off each relay in the group
using the individual Relay Control Buttons. When the last relay is turned off,
the channel LED should also go off.

DATA ENTRY
Data entry for the BMS Interface Module
simply involves entering scenario data
and defining the contacts for each
channel, as documented on the BMS
Interface Module Automation Scenarios
form (see Figure 2 on page 4). Once
that’s been done, the module has all the
information necessary to control the
Lighting Integrator.
To illustrate the data entry process, we’ll
use the actual data from the sample
application defined on page 3 and shown
in Figure 1.
INTERIOR LIGHTING
Channel A –
Manual ON/Scheduled OFF
To begin programming a channel, press
and hold the channel button on the face
of the BMS Interface Module. The LED
above the button begins to flash RED and
the screen displays:
The field that can be modified, in this case
the scenario choice in the second line,
will be flashing. Use the UP or DOWN key
to toggle the scenario between Sch ON/
OFF and Man ON/Sch OFF. If a Photocell
Control Module is also connected to the
system, the Dark ON/OFF and Dark ON/
Sch OFF scenarios will also be available.
When the correct scenario appears on
screen, press the NEXT key to select that
choice and advance to the next screen
Use the UP or DOWN key to enter the
length of the override Time Delay (in 10-
minute increments up to 240 minutes) for
relays smartwired to this channel. When
correct, press NEXT.
Use the UP or DOWN key to toggle
between YES or NO to enable or disable
the Blink Warn feature. When ready,
press NEXT
Set the Egress Time in the same way
using the UP or DOWN key. (000 for
none, 001 for test, 010 to 240 in 10-
minute increments). For channel A in this
example, no egress time is desired, so
leave the flashing field at 000 and press
NEXT.
Contact Definition
Once the scenario data has been entered,
the final step in channel programming
is to define the properties of the Input
Contact coming from the BMS or other
system, and the Status Contact reporting
back to the BMS, pilot light or other
system
The Input Contact is defined as either
Open or Closed (dry contact, maintained
– see Figure 4 on page 5) to indicate that
the lighting controlled by this channel
should be considered Occupied. Toggle
between these choices using the UP
or DOWN key. When the correct option
is flashing, press NEXT to select and
advance to the next screen.
CHANNEL STATUS
After power-up, the screen will display
the current states of the 8 global
channels on the network as shown below.
+ All relays ON
– All relays OFF
M Mixed state (some ON, some OFF)
(Blank) Channel not smartwired to any
relays
The LEDs for each channel on the face
of the BMS Interface Module may also
light up. LED indication reflects the
states associated with the input contacts,
and not the actual state of the channels
(actual composite channel state is shown
on the Channel Status screen).
Channel Input LEDs on the face of the
BMS Interface Module indicate:
Flashing Red Channel in Program mode
Steady Red Input Contact is Closed
Off Input Contact is Open
Steady Green Channel in Egress Delay
THE HBMS8SS KEYPAD
The BMS Interface Module’s keypad is
composed of three keys as follows:
UP and DOWN keys for modifying data
fields.
A NEXT key which confirms data entries
and advances to the next appropriate
screen or data field.
Channel Status Screen
Channel Button & Channel Input LED
HBMS8SS Building Management System Interface Module — Installation and Setup

The Status Contact can also be defined
depending on what feedback is required
by the BMS system. Choices for the
Closed contact definition include:
• Any ON (when any relays in any Channel
A in any panel are on, the status
contact will be closed)
• All ON (every relay in every Channel A
must be on for the status contact to be
closed)
• All OFF (every relay in every Channel A
must be off for the status contact to be
closed)
• Any OFF (when any relays in any
Channel A in any panel are off, the
status contact will be closed)
Programming for Channel A is now
complete. Press NEXT to SAVE Channel
A Program Changes. (If you need to start
over, use the UP or DOWN key to change
SAVE to CANCEL and press NEXT.)
After a brief message, the BMS Interface
Module will return to its main Channel
Status Screen.
Channel B –
Scheduled ON/OFF
The data entry procedure for Channel B
in our example follows the same steps as
Channel A.
EXTERIOR LIGHTING
Photocell Control Module
The two “Dark” scenarios only appear
as options in the BMS Interface Module
when the HPCU8SS Photocell Control
Module is connected to the dataline.
For detailed instructions on wiring the
HPCU8SS and its associated HPSA
Photocell Sensor, refer to HPCP8
instructions for those units.
Channel C –
Dark ON/OFF
The security lighting associated with
Channel C in our example is to turn on
every night and turn off every morning.
In this example, “Dark” is defined as 20
footcandles.
Begin programming Channel C as
before, by pressing and holding the
button marked C on the face of the BMS
Interface Module.
The scenario choice in the second line,
will be flashing. Using the UP or DOWN
key, toggle through the scenario choices
until Dark ON is displayed. Press NEXT:
The flashing second line will prompt for a
footcandle setting from 002 to 200 in 1 fc
increments. Press the UP or DOWN key
to scroll through the numbers until the
desired footcandle level is reached (Hint:
Hold down the UP or DOWN key to scroll
continuously). Press NEXT:
With the Dark ON/OFF scenario, there is
no need for an Input Contact since there
is no reference to building occupancy. The
only criterion for lights turning ON or OFF
is exterior light level. (Security lighting
will turn on when it’s dark, whether the
building is occupied or not).
Set the definition of the Status Contact
for Channel C as before and press NEXT.
Press NEXT again to SAVE programming
for Channel C, or use the UP or DOWN
key to toggle to CANCEL and start again.
Channel D –
Dark ON/Scheduled OFF
Parking lot lighting should turn ON
when it is dark and turn OFF after
the building is unoccupied. With this
scenario, the lighting will only be turned
on if the building is occupied and it is
“dark.” Again, we defined dark in this
example as 20 fc. An egress delay allows
the parking lot lighting to stay on for a
defined period of time after the building
goes “unoccupied,” to allow safe exit for
occupants.
To program this scenario, press and hold
channel button D on the face of the BMS
Interface Module. The scenario line will
be flashing as before. Using the UP or
DOWN key, toggle through the scenario
choices until Dark ON/Sch OFF is
displayed. Press NEXT.
Using the UP or DOWN key, set the
Egress Delay time for Channel D for 000,
001, or from 010 - 240 minutes in 10
minute increments. In this example, the
egress delay is one hour, or 060 minutes.
Press NEXT.
As in the previous example, the flashing
second line will prompt for a footcandle
setting from 002 to 200 fc. Use the UP or
DOWN key to scroll through the numbers
until the desired footcandle level is
reached. Press NEXT.
Set the definition of the Input and Status
Contacts for Channel D as shown in the
Channel A example and press NEXT.
Choose SAVE or CANCEL and press
NEXT.

TESTING
When data entry is complete, be sure to
return to the Channel Status screen. The
BMS Interface Module must be displaying
this screen for the scenarios to operate
properly.
Using the Relay Schedule forms, confirm
that the correct relays are smartwired to
each channel in their panels.
Confirm that each channel in the BMS
Interface Module program has the proper
scenario entries and contact definitions.
For each channel, press the button on the
face of the unit and sequence through the
entries using the NEXT key to verify that
all data has been entered correctly.
When you have confirmed the data for
each channel, you can run a real-time
test using input from the BMS system. Or
simulate the BMS input for each channel
by using a two-wire maintained switch to
open or close the contacts and observe
how the channel responds.
For the two “Dark” (exterior lighting)
scenarios, detailed procedures for testing
using the Photocell Control Module
are included in the instructions for the
HPCP8.
