Edwards E-ISO Analog SLC Fault Isolator Module Installation Sheet

Analog SLC Fault Isolator Module Sheet module is an analog addressable device used to protect a A SLC from total collapse due to wire to wire short The module monitors line voltages and opens the SLC a short is detected A short is isolated between the two located electrically closest to the short device address is set using the two rotary switches located the front of the module One device address is required operation module provides a bicolor LED that shows its status Green LED flashes Red LED flashes module will not operate without electrical power As frequently cause power interruption you should further safeguards with your local fire protection module does not support conventional smoke The module is shipped from the factory as an assembled it contains no user serviceable parts and should not be install the module Verify that all field wiring is free of opens shorts and faults Make all wiring connections as shown in Set the module address as follows a screwdriver to adjust the two rotary switches on the of the module Set the TENS rotary switch 0 through for the 10s and 100s digit and the ONES rotary switch the 0 through 9 digit For example device address 21 TENS rotary switch to 2 and set the ONES rotary to 1 to for available address numbers Mount the module on the electrical box using screws with the electrical box Mount the wall plate on the module using 4 24 x 1 2 in mm self tapping screws 1 Module address 2 Module installation box plate 2013 UTC Fire Security All rights reserved 2 3101197 REV 02 REB 28JAN13 in accordance with NFPA 72 and CAN ULC S524 Be to observe the polarity of the wires as shown in the 3 Module wiring next OUT IN 4 maximum wire resistance refer to the appropriate manufacturer s documentation Maximum 12 AWG 2.5 mm2 wire Refer to the control panel technical reference manual for wiring specifications This module should be used only with Class A wiring Maximum circuit resistance between isolators is 6 wiring is power limited and supervised 20.6 V peak to peak k to 120 F 0 to 49 C to 93 RH noncondensing at F 32 C to 140 F to 60 C American 4 inch square x in 64 mm deep 2 gang box 4 in square box 1 1 2 in mm deep 14 16 or 18 AWG wire 2.5 1.5 or 0.75 mm2 Sizes 16 and 18 are preferred to 64 64 point control panel to 127 127 point control panel line voltage fault impedance circuit resistance isolators environment temperature range electrical boxes size address 2 3101197 REV 02 REB 28JAN13
