FFT-HSC Installation 
Instructions
The FFT-HSC Fire Fighter Handset Cabinet is 
used to store FFT-FHS handsets.
Compatibility
The FFT-HSC is compatible with the Silent 
Knight FFT series Fire Fighters Telephone. For 
more information refer to the IFP-FFT 
installation manual 54708 or the SK-FFT 
installation manual 54711.
Mounting
Mount the FFT-HSC cabinet so it is firmly 
secured to the wall surface. When mounting on 
concrete, especially when moisture is expected, 
attach a piece of 3/4 inch plywood to the 
concrete surface and then attach the cabinet to 
the plywood. 
The cabinet can be surface or flush mount. If you 
will flush mount the cabinet, the hole for the 
enclosure should be 14.75" W x 25" H x 4" D. 
Do NOT flush mount in a wall designated as a 
firebreak.
