Installation Instructions STRI S STRI D STRI R Switch Interface Modules STRI Series Addressable Modules from Building Technologies Inc shown in 1 interface direct shorting devices to the loop circuit of the FS 250C System STRI modules are available in three models STRI S and STRI R can monitor a normally or closed dry contact The STRI S can only and report the status of the contact while STRI R incorporates an addressable Form C The STRI D is a dual input module that and monitors two sets of dry contacts connect the STRI to the Programmer Tester the plug from the SDPU provided with the Pro into the on the front of the Be sure to insert the tab on the plug into the for the locating tab on the as shown in Figure 2 prevent potential damage to SDPU DO NOT connect an to the SDPU until at least wire is removed from 1 or 2 of the STRI to Figure 2 to locate the opening on the STRI cover that allows access to the holes which are on the STRI printed circuit board 1 Module FOR TAB FROM 2 The SDPU Plug Building Technologies Safety 315 049475C 4 to Figure 3 Follow the instructions in the SDPU Manual P N 315 033260C to the STRI to the desired address Record the device address on the label on the STRI front panel The STRI can now be installed and wired to the CLOSED OPEN NOTE 4 NOTES 2 AND 3 OF LINE OHMS OF LINE OHMS There can be any number of normally closed or normally open switches The end of line resistor must be located at the last switch Do not wire a normally closed switch across the end of line resistor Only for use with status applications 3 Switches to Figures 4 9 Refer to the appropriate wiring diagram below and wire the interface module accordingly wire size AWG minimum AWG maximum larger than 14 AWG can damage the connector Limited Wiring compliance with NEC Article 760 all power limited fire protective signaling must be separated a minimum of inch from all of the items located within an outlet box light 1 or non power limited fire protective signaling conductors meet the above requirements the following guidelines must be observed when this interface module power limited wiring is not used within this outlet box then these guidelines do apply In that case be sure to follow standard wiring practices Control Module GANG BOX 1 2 INCHES DEEP SQUARE BOX 1 8 INCHES DEEP STRI R Control Module must be used when STRI R relay contacts are to
