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

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.

Installation And Smartwiring

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 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.
