Addressable Switch Interface Modules
INTRODUCTION The HTRI Series Addressable Modules from
Siemens Industry, Inc., shown in Figure 1, interface
direct shorting devices to the DLC loop circuit of
the FireFinder-XLS or FS-250 System.
The HTRI modules are available in three models.
The HTRI-S and HTRI-R can monitor a normally
open or closed dry contact. The HTRI-S can only
monitor and report the status of the contact, while
the HTRI-R incorporates an addressable Form C
relay. The HTRI-D is a dual input module that
supervises and monitors two sets of dry contacts.
PROGRAMMING INSTRUCTIONS
Figure 1
HTRI Module
Refer to Figure 2 to locate the opening on the HTRI cover that allows access to the
programming holes which are on the HTRI printed circuit board.
To connect the HTRI to the DPU
Programmer/Tester, insert the
plug from the DPU cable
provided with the Programmer/
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
cnunoN
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
program 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
system.

NOTES:
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. Only for use with security and status applications.
5. Do not use N.O. switches for security applications.

WIRING (Refer to Figures 4 -9 ) Refer to the appropriate wiring diagram below and wire the
addressable interface module accordingly.
Wiiii� Recommended wire size: 18AWG minimum
14AWG maximum
Wire largerthan 14AWG can damage the connector.
Power Limited Wiring In compliance with NEC Article 760, all power limited fire protective signaling
conductors must be separated a minimum of 1/4 inch from all of the
following items located within an outlet box:
NOTE
HTRI-R Control Module
Barrier
• electric light
• power
• Class 1 or non -power limited fire protective signaling conductors
To meet the above requirements, the following guidelines must be observed when
installing this interface module.
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.
The HTRI-R Control Module
Barrier must be used when
the HTRI-R relay contacts are
connected to non -power
limited lines. Break apart the
barrier to the correct size and
shape shown in Figure 4 for
either the 4-inch square or
double gang box. Install the
barrier diagonally into the
backbox to create two
separate compartments
within the backbox to
separate the wires, as shown
in Figure 4.

Wiring Entering Outlet Box All power limited wiring must enter the outlet box separately from the electric light,
power, Class 1, or non -powered limited fire protection signaling conductors. For the
TRI-R, wiring to terminal block positions 1, 2, 3, 4, and 5 must enter the outlet box
separately from terminals 6, 7, and 8.
EF:§:_ Minimize the length of wire entering the outlet box.
WIRING ATTHETERMINAL BLOCKS
Power Limited Wiring (Refer to Figure 5) Wiring to positions
1, 2, 3, 4, and 5 is power limited.
Non -Power Limited Wiring Wiring to positions 6, 7, and 8 is considered
non -power limited.
