Before Installing

This information is included as a quick reference installation guide. Refer to the control panel installation 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.

NOTICE: This manual should be left with the owner/user of this equipment.

General Description

The M502M Interface Module is intended for use in intelligent, two-wire systems, where the individual address of each module is selected using the built-in rotary decade switches. This module allows intelligent panels to interface and monitor two-wire conventional smoke detectors. It transmits the status (normal, open, or alarm) of one full zone of conventional detectors back to the control panel. All two-wire detectors being monitored must be UL compatible with this module. The M502M has a panel controlled LED indicator.

Compatibility Requirements

To ensure proper operation, these modules shall be connected to listed compatible system control panels only.

Mounting

The M502M mounts directly to 4˝ square electrical boxes (see Figure 2A). The box must have a minimum depth of 2 electrical boxes (SMB500) are available from System Sensor.

⁄2˝ H x 4˝ W x 11⁄4˝ D (Mounts to a 4˝ square by 21⁄8˝ deep box.)

Wiring

NOTE: All wiring must conform to applicable local codes, ordinances, and regulations. This module is intended for power-limited wiring only.

1. Install module wiring in accordance with the job drawings and appropriate wiring diagrams.

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

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