Siemens HLIM Loop Isolator Module, Installation Instructions

Installation Instructions HLIM Isolator Module 1 Module RATINGS Model HLIM Loop Isolator Module from Siemens Industry Inc isolates short on FireFinder XLS or FS 250 analog loops By placing devices between HLIMs installation a short in the wiring within that group is disconnected from the of the loop The remainder of the devices continue to operate The HLIM oper in both Class A and Class B circuits yellow LED flashes when a device detects a short circuit The HLIM then isolates part of the loop When the short is removed the HLIM automatically restores the to normal operation The HLIM does not have a loop address and therefore does require address programming nor does it reduce the loop capacity below 252 all system power before installation first the battery and then the AC HLIM is a polarity insensitive module Refer to Figure 1 for the location of the input terminals two output terminals and earth ground Line 1 and Line 2 can be line of the loop Number Line 1 Line 2 Line 1 Line 2 Ground SQUARE BOX 1 8 INCHES DEEP GANG BOX 1 2 INCHES DEEP Mechanical Installation See Figure 2 Use a standard 3 1 2 inch deep double gang electrical or a 4 inch square electrical box that is 2 1 8 inches Connect the field wiring Press the HLIM into the box and the module plate to the box Cover the module front plate with the plate supplied and with screws supplied SQUARE Inc Inc Inc Industry Inc Inc TTTTTececececechnologies Di Di Di Division Di SQUARE 2 the HLIM 315 034904 4 B All wiring must comply with and local codes order to provide adequate it is recom that you do not more than 20 devices a single HLIM 18 AWG minimum 14 AWG The total wire resistance wires between HLIMs exceed 20 ohms Do not install more than 15 per DLC FS DLC All circuits are supervised Refer to DLC Installation P N 315 033090 the FS 250 Manual P N for the list of devices as All terminals are power A Single Loop All wiring must comply with and local codes order to provide adequate it is recom that you do not more than 20 devices a single HLIM 18 AWG minimum 14 AWG The total wire resistance wires between HLIMs exceed 20 ohms Do not install more than 15 per DLC FS DLC All circuits are supervised Refer to DLC Installation P N 315 033090 the FS 250 Manual P N for the list of devices as All terminals are power Industry Inc Technologies Division Park NJ HLIM may be used in two circuit configurations as follows Figure 3 In Class B wiring each HLIM isolates a branch on the circuit Note that short on the main branch causes the entire loop to fail To prevent this mount the at the enclosure and run each branch independently LOOP 1 2 OUT OUT EARTH OUT OUT OUT OUT 3 Wiring Diagram Class B Installation Figure 4 In Class A wiring the HLIMs are wired in series with the loop wiring results in a single continuous loop If any group in the loop has a short that is lost and a Class A circuit failure results FireFinder XLS displays communication errors for the devices and a A failure for the loop itself FS 250 displays the message Open and response for in the groups on the loop that follow the short ENCLOSURE ANALOG RETURN 2 1 1 2 ANALOG FEED IN OUT OUT IN OUT OUT EARTH IN OUT OUT EARTH 4 Wiring Diagram Class A Installation Single Loop Building Technologies Ltd Safety Security Products Kenview Boulevard Ontario 5E4 Canada 315 034904 4
