The ANSREM is a supervised remote microphone for use with the ANS voice evacuation system. The microphone provides crystal-clear live voice messages over the system speakers. Up to five ANSREM panels may be connected to a single ANSREMSUP supervisory card. This provides supervision of the wires to the AN-SREM and supports wiring distances of up to 5,000 feet (1,524 meters). The ANSREM is housed in an attractive surface or semi-flush mounted enclosure, with a hinged locking door. It features deadfront construction, a microphone with a “Press-to-Talk” button, and discreet LEDs that indicate In-Use and Fault status.

The ANSBKUP switching card continually monitors the primary amplifier for signs of failure. Should the amplifier fail, the ANSBKUP automatically activates a backup amplifier. A single amplifier can be used to back up one or more amplifiers of equal or lesser wattage. One ANSBKUP is required for each amplifier being backed up. The backup amplifier does not require its own microphone and digital message repeater unless a fully redundant voice evacuation system is required
