GENERAL ALERT

Warning

Electrical Hazard:

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 Device Configuration Page on the web interface for relay settings.

This relay can be used to trigger low current devices like strobes and security camera input signals

s long as the load is not an inductive type and the relay is limited to a maximum of 

1 Amp @ 30 VDC. Inductive loads have caused excessive “hum” and can interfere with the unit’s

lectronics.

We highly recommend that inductive load and high current

devices use our Door Strike Intermediate

Relay product (CD# 011269) (see Section 2.3.3.2, "Connecting the Door Strike Intermediate Relay

Module").

This relay interface also has a general purpose input port that can be used to monitor an external

witch and generate an event.

For more information on the sensor options, see the Sensor Configuration Page on the web

interface.

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.
