SSJ-FT 904 A Fire Fighter Telephone Jack
A brushed stainless steel jack plate that gives firefighters a fixed, supervised plug-in point on every floor. Plug in an FFTH-901 handset and you are speaking to the fire control room over the Agni FFTS-900 Series EVCS.
Firefighter Communication, on a line that never depends on radio coverage
The AGNI-SSJ-FT-904-A is a dedicated emergency fire phone jack. Where a fire telephone system needs handset points beyond the control room, this jack plate provides them: in corridors, staircases, lift lobbies and service areas of high-rise buildings, shopping malls, offices, hospitals, and industrial or commercial complexes.
The plate is made from heavy brushed 304 grade corrosion-resistant stainless steel, so it stays legible and highly visible on the wall. It works asa firefighter telephone socket for the portable FFTH-901 handset, and it links to the central control room throught the FFT-900 Searies EVCS. That gives the fireman communication system a reliable two-way voice path in an emergency.
Because the jack wires into a monitor module rater than a proprietary bus, the datasheet states it is compatible with and brand of addressable monitor module. Fire fighter communication system designers can add jack points without changing their panel platform.

Choose The Ideal Fire Fighter Telephone Jack
Each jack is a remote firefighter phone jack point: a socket on the wall that leads back to the control room. Around it sit the other parts a firefighter needs: the handset, and the jack plate in the material and size your project calls for. All three jack plates share the same electrical specification, so you choose between them by material, plate size and finish.
