Simplex (2084-9017) Firefighter phone assembly, locked door, surface mounting, break-rod door with handle, armored cable phone, push-to-talk phone

The Simplex 2084-9017 is a surface-mount firefighter telephone assembly with a locked, break-rod door and an armored push-to-talk handset. Specifically, it is part of the Simplex 2084 series of remote firefighter telephones. Firefighter telephone systems give first responders a dedicated two-way voice channel inside a building.

Firefighters rely on these phones when radio communications inside a structure are unreliable. For example, large concrete buildings, parking decks, and high-rise stairwells often block portable radio signals. As a result, code requires a hardwired firefighter telephone system in many commercial buildings. Therefore, the 2084-9017 jack station is installed at strategic locations such as elevator lobbies and stairwell landings.

How the Simplex 2084-9017 break-rod door works

A glass break-rod sits behind the door handle. First, the responder pulls the handle. Then the rod breaks and the door swings open. As a result, the armored handset is immediately available for use. In addition, the locked door prevents tampering between events while leaving the phone accessible to authorized personnel during an alarm or test.

Common applications

The 2084-9017 typically installs in elevator lobbies, stairwell landings, mechanical rooms, and other locations identified on the building’s firefighter telephone riser. Also, the surface-mount form factor lets a contractor add the device to an existing structure without a recessed back-box rough-in. Furthermore, the armored cable resists hand-pulling damage during emergency use.
