Warning
Electrical Hazard:
The SIP Weatherproof Keypad Phone incorporates one on-board relay located on the PCBA, which
enables users to control a low current external relay or device (see
). 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.
The device relay activation time is selectable through the web interface on the Device Configuration
Page (see
Section 2.3.11, "Configure the Device"
). 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 device has a built-in relay that can be activated by a web configurable DTMF string that can be
received from a VoIP phone supporting out of band (RFC2833) DTMF as well as a number of other
triggering events. See the
on the web interface for relay settings.
This relay can be used to trigger low current devices like LED strobes and security camera input.
This product should be installed by a licensed electrician
according to all local electrical and building codes.
The relay contacts are dry and provided for a normally open
and momentarily closed configuration. Neither the alternate power input nor PoE
power can be used to drive a door strike.
The relay does not support AC powered door strikes.
Any use of this relay beyond its normal operating range can cause damage to the
product and is not covered under our warranty policy.
Warning
Equipment Hazard:
The relay circuitry contains a non-replaceable 250VAC 1A
fuse. If the fuse blows, the board must be returned to CyberData or an approved
service center for repair.
