STRI Module

INTRODUCTION The STRI Series Addressable Modules from

Siemens Building Technologies, Inc., shown in

Figure 1, interface direct shorting devices to the

FDLC loop circuit of the FS-250C System.

The STRI modules are available in three models.

The STRI-S and STRI-R can monitor a normally

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

monitor and report the status of the contact, while

the STRI-R incorporates an addressable Form C

relay. The STRI-D is a dual input module that

supervises and monitors two sets of dry contacts.

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

programming holes which are on the STRI printed circuit board.

To connect the STRI to the

SDPU Programmer/Tester,

insert the plug from the SDPU

cable provided with the Pro-

grammer/Tester into the

opening on the front of the

STRI. Be sure to insert the

locating tab on the plug into the

slot for the locating tab on the

STRI as shown in Figure 2.

To prevent potential damage to

the SDPU DO NOT connect an

STRI to the SDPU until at least

one wire is removed from

terminals 1 or 2 of the STRI.

(Refer to Figure 3.) Follow the instructions in the SDPU Manual (P/N 315-033260C) to program the STRI to the desired address. Record the device address on the label located on the STRI front panel. The STRI can now be installed and wired to the system.

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. Minimize the length of wire entering the outlet box. WIRES CONNECTED TO TERMINALS 1 THROUGH 5 TO ENTER/EXIT ELECTRICAL BOX OPPOSITE SIDE FROM WIRES CONNECTED TO TERMINALS 6 THROUGH 8.

(Cont’d From Previous Page): 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. Positive and negative ground fault detected at <60K ohms for terminals 3 and 4.
