Simplex 2081-9028 5 A Isolated Loop Circuit Protector (ILCP) (B) (C) (D)

ULC CSFM Listed Loop Circuit Protector ILCP for up to A of DC or audio current Low impedance design minimizes voltage drop For internal or external applications refer to page 2 for wiring requirements Refer to specific panel field wiring diagrams for application information Listed as an Isolated Loop Circuit Protector to UL 497B for Data Communications and Fire Alarm Listed as a Surge Suppressor to ULC S527 Control for Fire Alarm Systems See Note 1 below for additional application reference For lower current ILCP applications up to 200 mA to Model 2081 9027 on data sheet S2081 0007 SLCs IDNAC SLCs and TrueAlert SLCs is compatible with DC notification appliance circuits NACs Speaker circuit NACs 25 VRMS Other circuit types see Note 2 below stages of protection for DC and audio Line to Line Protection Line to Earth protection epoxy encapsulated package transients caused by lightning or by on high voltage power lines are conditions that low voltage wiring circuits to be adequately This protection is most effective when placed at location where such circuits leave or enter the building Protection The 2081 9028 Isolated Loop Protector ILCP is designed to protect Simplex Alarm circuits from those electrical transients induced wire runs that are routed external to the building of its small package size it can be easily mounted the location that achieves maximum protection 1 Overvoltage Protector Applications Model is for use as an Isolated Loop Circuit Protector is different from operation as an Overvoltage For Overvoltage Protector applications refer to Protector model 2081 9044 which is listed to 864 rated for up to 200 mA and documented on data S2081 0016 2 Operation with other Circuit Types of the 2081 9028 ILCP has been quantified use with other circuit types

individual system installation instructions including properly twisted and shielded pairs and observance of following precautions To ensure optimized protection the ILCPs shall be located as close as possible to point at which the circuits leave or enter the buildings installed in dedicated metallic electrical boxes Distance Wiring is limited to one contiguous The total maximum wire length is determined the individual application allowable limit as with ILCPs but must not exceed 3270 ft 1 km Wiring Wiring must be in a wiring that is separate from commercial power wiring Wiring Wiring must be run on poles separate from those any commercial power distribution Wiring shall be run in parallel with the commercial distribution wiring and be separated by a distance of either 100 ft 30 m or the span between any two adjacent poles of the system circuit or the commercial power circuit Conductor The grounding conductor shall be AWG 3.31 mm2 with a maximum length of 28 ft m run in as
