INSTALLATION INSTRUCTIONS FOR M302(A)

TWO-WIRE CONVENTIONAL DETECTOR MONITOR MODULE

This information is included with the modules as a quick reference installation guide. Refer to the appropriate Fire-Lite product manual for detailed system information. If the modules will be installed in an existing operational system, inform the operator and local authority that the system will be temporarily out of service. Disconnect power to the control panel before installing the modules.

GENERAL DESCRIPTION

The M302(A) monitor module allows addressable panels to interface and monitor two-wire conventional smoke detectors. All two-wire detectors being monitored must be UL compatible with the module.

The module is addressed through the communication line (SLC) of addressable systems. When the module is interrogated, it transmits the status of one zone of two-wire detectors to an addressable control panel. Status conditions are reported as NORMAL, OPEN, or ALARM. The monitor module supervises the zone of detectors and the connection of a power source.

STATUS LED

ROTARY DECADE ADDRESS SWITCHES

MAGNET TEST POSITION

Two rotary decade switches allow setting module addresses from 00–99. A status LED indicator is provided and is controlled by code command from the control panel. The module provides a magnetically activated test switch for testing the module’s electronics and connections to the control panel (see Fig-

MODULE CONTROLS AND INDICATORS

ure 1).

COMPATIBILITY REQUIREMENTS

To insure proper operation, this module shall be connected to compatible Fire-Lite addressable control panels only. Conventional two-wire smoke detectors must be UL compatible with the UL

listed monitor module. For the ULC listed monitor module, the conventional 2wire smoke detectors must be ULC compatible with the monitor module. A list of compatible two-wire conventional detectors is available from Fire-Lite (P/N

15384).

PACKAGE CONTENTS

(1) Two-wire monitor module, P/N M302 (1) 3.9K ohm end-of-line resistor (A2143-10) (1) Off-white cover plate (1) Screw pack for cover plate

MOUNTING

The M302(A) monitor module mounts directly to a 4 inch square electrical box as shown in Figure 2. The box must have a minimum depth of 2-1/8 inches.

WIRING

NOTE: All wiring must conform to applicable local codes, ordinances and reg-

ulations.

1. Install module wiring in accordance with the job drawings and appropriate wiring diagrams (Figures 3 – 5).

2. Set the address on the module per job drawings.

3. Secure the module to the electrical box (supplied by installer), as shown in Figure 2.

4. Perform steps one, two, and three for all modules.

TESTING

The M302(A) monitor module can be tested with a test magnet available from Fire-Lite (M02-04-00, see Figure 1). The magnet test checks the module’s electronics and connections to the control panel. Interfaced two-wire detectors must be tested independently. Test two-wire detectors per manufacturer’s installation instructions.
