Fire telephone and stadium marshal systems use ‘Type A’ telephone-style outstations. Sig-Com CH/EV301RLK Type A Outstations comprise a telephone handset in a lockable red steel cabinet. They are typically located at entrances and fire-fighting lobbies to allow fire marshals to communicate with building control during an emergency.
Their housings have openings which allow the phones to be heard and they are designed to be surface or semiflush mounted using the CH/T-BEZ Bezel. A Type A outstation with ‘push-to-open’ access (the CH/EVC301RPO) is also available.
