MAM Y, Automatic siren control device (LSCM 1)

Global Fire Equipment MAM LSC Output Manually Addressed Module

Manually addressed interface module allowing connection and addressing of conventional sounders/beacons within an addressable fire alarm loop, enabling retrofit of conventional components into an addressable system.

Main Features:

• Loop-powered: 17 V to 30 V DC
• Quiescent loop current: ~1.1 mA
• Alarm loop current: ~12 mA when output active
• Address range: 1-125 for detectors/MCP/I/O or 94-125 for sounder/beacon devices
• Max cable size: up to 2.5 mm² conductors
• Operating temperature: ?10 °C to +50 °C; Maximum humidity: 95 % RH non-condensing
• Compact dimensions: 48 mm × 24 mm × 12 mm; Weight: ~18 g
• 8-way DIP switch for address and mode configuration (e.g., sounder vs beacon behaviour)

Notes:

• Ensure loop wiring meets specification and that module quiescent + alarm currents are included in loop load calculations.
• Switching between sounder and beacon modes can be achieved via DIP switch settings according to installation requirements.
• When used for retrofit, ensure conventional sounder/beacon connected to module is compatible with its output behaviour and that the system’s panel supports the module.
• Professional installation is recommended to ensure reliable integration and full system compliance.
