2.9.2 Using the On-Board Relay
The CyberData 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
relay settings.
This relay can be used to trigger low current devices like strobes and security camera input signals
as 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
electronics.
We highly recommend that inductive load and high current devices use our Door Strike Intermediate
Relay product (CD# 011269) (see
Module").
This relay interface also has a general purpose input port that can be used to monitor an external
switch and generate an event.
For more information on the sensor options, see the
interface.
