GSA-RM1 and MRM1 Riser Monitor Modules are intelligent analog addressable devices that form part of Vigilant's Signature line of products. The actual operation of the GSA-RM1 and MRM1 is determined by the "personality code" selected by the installer, which is downloaded to the module from the Signature loop controller during system configuration.

Depending on their assigned personality, Riser Monitor Modules may be used to monitor telephone risers or 70 Vac audio, 25 Vac audio, or 12 Vdc to 24 Vdc risers.

Upon the loss of a signal, the fire alarm control panel indicates an alert status. The Riser Monitor Module requires one module address.
