Adds up to 3 zones of two way listen-in to M1 Control Panels.
The M1TWI Interface allows microphones to be connected to the M1 for two way voice verification and listen-in. It features 3 separate microphone zones with up to 4 microphones per zone (up to 12 microphones (M1TWS) may be connected). Programming options and operation procedures are already built into the M1 control.
This can be used by the central station to verify an alarm, or by a user from the telephone remote control to check on elderly parents, children, etc.
