The System Sensor M500DM is a dual monitor module for intelligent, two-wire fire alarm systems. It provides two independent initiating device circuits at two consecutive addresses. As a result, a single module supervises two separate input circuits.
The module monitors normally open fire alarm and supervisory contacts. In addition, it can monitor normally open or normally closed security devices. Each circuit uses Class B supervised wiring.
System Sensor M500DM specifications
