HBMS8SS
Smartwired
™
BMS Interface Module
Installation and Setup
The Smartwired
™
Switching (SS) System is a small
network of relay panels and occupant control switches
linked by a 4-wire dataline. Together these devices
form a reconfigurable switching platform that uses
“smartwiring” instead of hardwiring to link occupant
switches to relays.
The Building Management System Interface Module
(HBMS8SS) provides an intelligent interface to
other building systems, such as HVAC or Security.
The HBMS8SS is used instead of a Network Clock
(HCLK8SS) to provide smart control scenarios for up
to eight global lighting groups (channels) in the
Smartwired Switching 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 SMARTWIRED SWITCHING
SYSTEM INSTALLATION AND OPERATION
MANUAL.

HBMS8SS Building Management System Interface Module — Installation and Setup
Operation
In a Smartwired
™
Switching System,
relays and their associated 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 capabil-
ity 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.
With the BMS Interface Module, the user
may assign an automation “scenario” to
any channel. The type of scenario
chosen depends on how the building
space is to be used.
Questions the user should ask include:
• Is it an interior or exterior space?
• Should occupants turn lights on when
they arrive, or should lights turn on
automatically?
• Do occupants need to be warned
when lights are about to turn off?
• Should exterior lighting stay on all
night, or turn off after the building is
closed?
On the HBMS8SS, each channel has its
own connection to an external source —
whether that’s the building’s 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 informa-
tion, 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.
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 instruc-
tions INHPCU8.
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)
* Only one Network Clock or BMS Interface Module
can be used in a single Smartwired Switching
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.

Sample Smartwired Switching System Application
To help illustrate how to program the
BMS Interface Module, the following
application, a two-story office building,
shown below in Figure 1, is used.
There is one Smartwired Switching 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 one-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 two-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 two-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 as-
signed 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 Smartwired Switching
System 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.
Step 4: Connect the BMS Interface
Module and Enter Data
Plug the attached cable into the LOCAL
DATALINE connector in any relay panel,
providing power to the BMS Interface
Module.
During the power-up sequence, the
screen will display the firmware version
number of the unit. Also, the LEDs on
the face of the unit will turn first Red,
then Green, then Off.

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 Sce-
narios form (see Figure 2 on page 4).
Once that’s been done, the module has
all the information necessary to control
the Smartwired Switching System.
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, main-
tained – 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.
After power-up, the screen will display
the current states of the eight global
channels on the SS 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 con-
tacts, 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:

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.

• 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

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 instructions
INHPCP8 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 program-
ming 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.

Testing
When data entry is complete, be sure to
return to the Channel Status screen. The
BMS Interface Module must be display-
ing 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
INHPCP8.
