HTRI Module

INTRODUCTION The SIEMENS Model HTRI Series Addressable

odules, shown in Figure 1, interface direct

shorting devices to the FireFinder-XLS Syste s

DLC loop circuit.

The HTRI odules are available in three odels.

The HTRI-S and HTRI-R can onitor a nor ally

open or closed dry contact. The HTRI-S can only

onitor and report the status of the contact,

while the HTRI-R incorporates an addressable

For C relay. The HTRI-D is a dual input odule

that supervises and onitors two sets of

dry contacts.

PROGRAMMING Refer to Figure 2 to locate the opening on the HTRI cover that allows access to the

progra ing holes which are on the HTRI printed circuit board.

To connect the HTRI to the

DPU Progra er/Tester,

insert the plug fro the DPU

cable provided with the

Progra er/Tester into the

opening on the front of the

HTRI. Be sure to insert the

locating tab on the plug into

the slot for the locating tab on

the HTRI as shown in Figure 2.

To prevent potential damage

to the DPU DO NOT connect

an HTRI to the DPU until at

least one wire is removed

from terminals 1 or 2 of the

HTRI.

(Refer to Figure 3.) Follow the instructions in the DPU Manual (P/N 315-033260) to

progra the HTRI to the desired address. Record the device address on the label

located on the HTRI front panel. The HTRI can now be installed and wired to the

syste .

WIRING (Refer to Figures 4 -9 ) Refer to the appropriate wiring diagra below and wire the

addressable interface odule accordingly.

Recommended wire size 18 AWG minimum

14 AWG maximum

Wire larger than 14 AWG can damage the connector.

Power Li ited Wiring In co pliance with NEC Article 760, all power li ited fire protective signaling conduc-

tors ust be separated a ini u of ¼ inch fro all of the

following ite s located within an outlet box:

 electric light

power

 Class 1 or non-power li ited fire protective signaling conductors

To eet the above the require ents, the following guidelines must be observed

when installing this interface odule.

If power limited wiring is not used within this outlet box, then these guidelines do

not apply. In that case, be

sure to follow standard

wiring practices.

HTRI-R Control Module The HTRI-R Control Module

Barrier ust be used when

the HTRI-R relay contacts are

connected to non-power

li ited lines. Install the

ther al plastic barrier

diagonally into the backbox

to create two separate

co part ents within the

backbox to separate the

wires, as shown in Figure 4.

N TES:

1. There can be any number of normally closed or normally open switches.

2. The end of line resistor must be located at the last switch.

3. Do not wire a normally closed switch across the end of line resistor.

4. nly for use with security and status applications.

5. Do not use N. . switches for security applications.

Wiring Entering Outlet Box All power li ited wiring ust enter the outlet box separately fro the electric light,

power, Class 1, or non-powered li ited fire protection signaling conductors. For the

TRI-R, wiring to ter inal block positions 1, 2, 3, 4, and 5 ust enter the outlet box

separately fro ter inals 6, 7, and 8.

Minimize the length of wire entering the outlet box.

WIRING AT THE TERMINAL BLOCKS

Power Li ited Wiring (Refer to Figure 5) Wiring to positions

1, 2, 3, 4, and 5 is power li ited.

Non-Power Li ited Wiring Wiring to positions 6, 7, and 8 is considered

non-power li ited.

Ground shield ONLY at the specified

location on the Control Panel.

NOTES:

1. All supervised switches

must be held closed and/or

open for at least a quarter of

a second to guarantee

detection.

2. End of line device: 3.6K, 1/4W

Canadian applications, use

Model EL-33 with 3.6K, 1/4W

resistor.

3. HTRI is polarity insensitive.

7. Terminal 5 must be

connected to earth ground.

a. Use wire nuts to pass the

shield wire through the

electrical box with NO

connection to the device

terminal block or to local

ground.

b. Use shielded wire to

connect the switch wiring.

c. Tie the switch wiring shield

to terminal 5 or the local

earth ground.

8. For proprietary burglary

application (Refer to Figure 9):

a. Use an HTSW-1 tamper

switch to monitor the main

enclosure.

b. Monitor each HTRI-S/-R/-D

related to this application

continuously by using a

listed motion detector (to

prevent tampering).

9. In supervisory:

HTRI-S/-R draws 1mA

HTRI-D draws 1mA

Figure 9

Security Point (1076) Wiring Connections

Terminal 5 of the HTRI-S/-D/-R must be connected to a known good earth ground for

proper operation.

MOUNTING Addressable Interface SIEMENS Models HTRI-S, HTRI-D, and HTRI-R ount directly

into a (user supplied) double gang or 4 inch switchbox. Fasten the odule to the

switchbox with the switchplate using the 2 screws provided.

A red LED will blink to indicate an off-nor al input switch position and/or an internal

relay transfer.

Be sure to program the HTRI before fastening the switchplate to the unit.
