Bases are used for MLINE beacons, sounders, or both in combination.
Multiple mounting options are available for M-LINE bases due to its unique modular concept, which allows various audio and/or signalling devices to be mounted in the most efficient manner.
Different DOMES (visual, audio, or both) can be installed on any of six different bases, which determine the unit's supply voltage (12–24 VAC/DC or 90–240 VAC).
