Siemens HLIM-Z Loop Isolator Module, Installation Instructions

Installation Instructions HLIM Z Isolator Module 1 Module RATINGS Model HLIM Z Loop Isolator Module from Siemens Industry Inc isolates short on FireFinder XLS or FS 250 analog loops By placing devices between HLIM during 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 Z in both Class A and Class B circuits yellow LED flashes when a device detects a short circuit The HLIM Z then isolates part of the loop When the short is removed the HLIM Z automatically restores loop to normal operation The HLIM Z does not have a loop address and there does not require address programming nor does it reduce the loop capacity 252 devices all system power before installation first the battery and then the AC HLIM Z 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 FS DLC Loop Current 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 Z 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 Z HLIM Z may be used in two circuit configurations as follows Figure 3 In Class B wiring each HLIM Z isolates a branch on the circuit Note a short on the main branch causes the entire loop to fail To prevent this mount HLIM Zs 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 HLIM Zs 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 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 Z 18 AWG minimum 14 AWG The total wire resistance wires between HLIM cannot exceed 20 ohms Do not install more than 15 per DLC FS DLC All circuits are supervised Refer to DLC Installation P N 315 or the FS 250 P N 315 049353 for list of compatible as applicable 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 Z 18 AWG minimum 14 AWG The total wire resistance wires between HLIM cannot exceed 20 ohms Do not install more than 15 per DLC FS DLC All circuits are supervised Refer to DLC Installation P N 315 or the FS 250 P N 315 049353 for list of compatible as applicable All terminals are power Industry Inc Technologies Division security disclaimer products and solutions provide security functions to ensure the secure operation of comfort fire safety security management and physical security systems The security on these products and solutions are important components of a comprehensive security is however necessary to implement and maintain a comprehensive state of the art security that is customized to individual security needs Such a security concept may result in site specific preventive action to ensure that the building comfort fire safety security or physical security system for your site are operated in a secure manner These may include but are not limited to separating networks physically protecting system user awareness programs defense in depth etc additional information on building technology security and our offerings contact your Siemens or project department We strongly recommend customers to follow our security advisories provide information on the latest security threats patches and other mitigation measures http www siemens com cert en cert security advisories htm Industry Inc Technologies Division PAGE HAS BEEN LEFT INTENTIONALLY BLANK Industry Inc Technologies Division Park NJ Canada Ltd North Service Road East Ontario 0H6 Canada A5Q00072132 ID A6V11208376 en a
