Connecting a Device to an Auxiliary Relay
The FT100C-V Telephone incorporates one on-board relay located on the PCBA, which enables users to control a low
current external relay or device. An external relay can control a ringer, strobe light, door lock or any other apparatus.
The on-board relay is protected by a 1 A, non-replaceable fuse. Power switched by the relay should not exceed 0.5 A at
30 Vdc. The PCBA is not designed to handle AC voltages.
The relay circuitry contains a non-replaceable 250 VAC 1 A fuse. If the fuse blows, the board must be returned to
Federal Signal or an approved service center for repair.
The telephone relay activation time is selectable through the web interface. The relay is controlled by DTMF tones
generated from the phone to which the VoIP phone is connected no matter which one initiated the call. The DTMF tones
are selectable from the web interface as well.
NOTE:
The three-digit code for the auxiliary relay must be sent in conformance with RFC2833 DTMF generation.
