EST Edwards M501MF Fire Alarm Mini Monitor Module - This compact addressable device provides a reliable interface for monitoring normally open dry contact initiators in life-safety systems. - Operating voltage range of 15.2 to 19.9 VDC - Maximum standby current of 450 microamps - Alarm current draw of 550 microamps - Operating temperature capacity between 32°F and 120°F - Compact form factor designed for easy integration into standard electrical boxes

Compared to previous generations of monitor modules, the M501MF offers a significantly reduced physical footprint, facilitating installation in tight spaces where standard-sized components cannot fit. This unit upholds the industry-standard protocols required for modern addressable fire alarm networks, ensuring seamless compatibility and consistent data reporting during emergency events.

Advanced Circuitry and Reliability

The M501MF utilizes high-precision internal circuitry to ensure rapid response times when a connected contact is closed. By maintaining an extremely low power profile during standby, this module supports extended system capacity without compromising the stability or speed of the fire alarm loop communication.
