Addressable Interface Module
PROGRAMMING
P/N 315-049480-4
The Model HTRI-M Series Addressable Interface
Module from Siemens Industry, Inc. interfaces
direct shorting devices to the DLC loop circuit of
the FireFinder-XLS System or the FS-DLC loop of
the FS-250 System. It is also approved for 1076,
Proprietary Burglary.
The HTRI-M can monitor a normally open or closed
dry contact and it can report the status of the contact.
Refer to Figure 1 to locate the red and black DLC/FS-DLC loop circuit wires of the HTRI-M.
Connect the Addressable Loop Driver circuit wires of the HTRI-M to the Model DPU
Programmer/Tester. Use the cable provided with the Programmer/Tester and the 2
alligator clip to banana plug adapters provided.
To Prevent Damage To The DPU:
DO NOT connect a HTRI-M to the DPU until all field wiring is removed from the
red and black DLC/FS-DLC loop circuit wires of the HTRI-M.
Connection from the DPU to the HTRI-M is not polarity sensitive. Refer to Figure
3 for the proper connections to the control panel.
(Refer to Figure 2.) Follow the instructions in the DPU Programmer/Tester Manual
(P/N 315-033260) to program the desired address into HTRI-M.
Record the device address on the label located on the HTRI-M. The HTRI-M can now
be installed and wired to the system.
