Connecting a Device to an Auxiliary Relay
The FT200C-VoIP Telephone incorporates a 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 the rating
of the fuse. Consideration of a safety factor is recommended.
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 on the Device Configuration Page. The relay
can be controlled by DTMF tones generated from the monitoring phone to which the VoIP phone is connected or by other
methods. Refer to VoIP Configuration Guide – Part Number 25500857.
NOTES:
•
The three-digit code for the auxiliary relay must be sent in conformance with RFC2833 DTMF generation.
•
Firmware version 3.4.0 or later requires a “#” to execute the DTMF command.
Example: 321# - activate relay.
