Product Overview

The Line Isolator Module (Model HLIM | HLIM-Z) provides protection of short circuits on the
signaling line circuits (SLC) via use with Siemens 50-point and 252/504-point addressable systems,
as well as the Class `X’ Device Loop Card (XDLC) for Modular panels {Model DLC for FireFinder
XLS/V.}

When a short circuit is detected, Model HLIM | HLIM-Z isolates the affected segment on the
circuit, allowing the remaining devices to continue functioning.

For Siemens Modular and FireFinder systems, up to 15 line-isolator modules (Model HLIM | HLIM-Z) may be wired on one (1) Model XDLC or DLC loop, respectively. For Siemens 50- point and 252/504-point addressable systems, up to 15 HLIM | HLIM-Z modules can be wired on one (1) SLC.

Model HLIM | HLIM-Z is self-restoring, and automatically reconnects to the circuit segment
when the fault is removed.

There is one (1) yellow LED, which indicates activation of the peripheral device. Model HLIM |
HLIM-Z can be wired in either a Style 4 or Style 6 configuration. Model HLIM | HLIM-Z does not
occupy a device address on any of the following: Model XLDC for Siemens’ Modular panels; {Model
DLC for FireFinder} or the SLC for the Siemens 50-point and 252/504-point addressable FACPs.

Model HLIM | HLIM-Z mounts to a 4" (10.2 cm.) square, 2-1/8" (5.4 cm.) deep or 3-1/2" (8.9 cm.)
deep, double-gang electrical box. A switch plate (with an opening for the LED) is included per order. There is no type of programming necessary for operation of each line-isolator module.
