ACR/ACT-VoIP Series Telephones
8.2. Connecting a Device to the Auxiliary Relay
The ACR/ACT-VoIP 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 could control a
ringer, strobe light, door lock or any other apparatus.
The on board relay is protected by a 1
Amp, non-replaceable fuse.
Power switched by the relay should not exceed 0.5
Amps @ 30VDC.
The PCBA is not designed to handle AC voltages
.
See: Figure 6 - Auxiliary
Relay Wiring Diagram
Warning: The relay circuitry contains a non-replaceable 250VAC 1A fuse. If the
fuse blows the board must be returned to Guardian 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 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.
See: Manual P007402
Setup and Configuration
Note:
The three digit code for the auxiliary relay must be sent in conformance with RFC2833
DTMF generation.
