Installation Instructions
Models TRI-S, TRI-D, TRI-R
Addressable Interface Modules
The SIEMENS Model TRI Series Addressable modules,
shown in Figure 1, interface direct shorting devices to the
MXL System's ALD loop circuit.
Note: The TRI-S/-D/-R Series is not compatible with
the XL3 System or the XLD-1 loop circuit.
The TRI modules are available in three models. The
TRI-S and TRI-R can monitor a normally open or closed
dry contact. The TRI-S model can only monitor and
report the status of the contact, while the TRI-R incorporates an addressable Form C relay. The TRI-D is a
dual input module that supervises and monitors two
sets of dry contacts. It requires two address settings.
Fire Safety
The TRI has a multi-color LED that flashes green when
operating normally, amber if the unit is in trouble
condition, and red to indicate a change of state. The
TRI-D flashes twice, once for each address. The TRI-R
red LED indicates a change of state in the relay.
PROGRAMMING INSTRUCTIONS
1. Refer to Figure 2 to locate the openings on the TRI
cover that allow access to the programming holes
which are on the TRI printed circuit board.
2. To connect the TRI to the SIEMENS FPI-32
Programmer/Tester, insert the plug from the FPI-32
cable provided with the Programmer/Tester into the
opening on the front of the TRI. Be sure to insert
the locating tab on the plug into the slot for the
locating tab on the TRI as shown in Figure 2.
CAUTION: TO PREVENT DAMAGE TO THE FPI-32,
DO NOT connect a TRI to the FPI-32 until
at least one wire is removed from terminals
1 or 2 of the TRI.
Note: Connection from the FPI-32 to the TRI is keyed.
Refer to Figures 5-8 for the proper connections to
the control panel.

3. (Refer to Figure 3.) Follow the instructions in the
FPI-32 Programmer/Tester Manual (P/N 315-
090077) to program the TRI to the following:
a. Desired address
b. Desired application for fire or proprietary
burglary (security)
c. Normally open or normally closed switch
1
a minimum of
/4 inch from all of the following items
located within an outlet box:
• electric light
• power
• Class 1 or non-power limited fire protective signaling conductors
To meet the above the requirements, the following
guidelines must be observed when installing this
interface module.
NOTE: If power limited wiring is not used within this
outlet box, then the following guidelines do not
apply. In that case, be sure to follow standard
wiring practices.
NOTES:
1. There can be any number of 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. Record the device address on the label located on
the TRI front panel. The TRI can now be installed
and wired to the system.

TRI-R CONTROL MODULE BARRIER
The TRI-R Control Module Barrier must be used when
the TRI-R relay contacts are connected to non-power
limited lines. Install the barrier diagonally into the backbox to create two separate compartments within the
backbox to separate the wires, as shown in Figure 4.

Installing the TRI-R Control Module Barrier
Refer to the appropriate wiring diagram below and wire
the addressable interface module accordingly.
Note: Recommended wire size:
18 AWG minimum
14 AWG maximum
Wire larger than 14 AWG can damage the
connector.
POWER LIMITED WIRING FOR TRI-R
ADDRESSABLE INTERFACE MODULE
In compliance with NEC Article 760, all power limited
fire protective signaling conductors must be separated
WIRING ENTERING OUTLET BOX
Power Limited Wiring
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.
IMPORTANT:
Minimize the length of wire
entering the outlet box.

WIRING AT THE TERMINAL 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 nonpower limited.
Note: Remove all slack from these wires by pulling
excess wiring back through the holes.

NOTES:
1. All supervised switches must be held closed and/or
open for at least a quarter of a second to guarantee
detection.
2. Use ULI listed EOL Model EL-30/31 mounting plate
with 470 ohms,
Model EL-30/31 separately.
3. The supervised switches have the following ratings:
Voltage maximum: 27 VDC
Current maximum: 3.5mA during polling
Contact resistance maximum: 10 ohms
