2.2.1.1 Calling with the The Call Button
You may initiate a call by pressing the Call button.
An active call is indicated by the Call Button LED blinking at one second intervals.
The Intercom can automatically answer an incoming call.
You can press the Call button to terminate an active call whether the call was an incoming call or a call that was initiated by you.
2.2.1.2 Call Button LED Function
Upon initial power or reset, the Call Button LED will illuminate.
When the software has finished initialization, the Call Button LED will blink twice.
When a call is established (not just ringing), the Call Button LED will blink.
On the Device Configuration Page, there is an option called Button Lit When Idle. This option sets the normal state for the indicator light. The Call Button LED will still blink during initialization and calls.
The Call Button LED flashes briefly at the beginning of RTFM mode.

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 a
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 e
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, "Door Strike Intermediate Relay").
This relay interface also has a general purpose input port that can be used to monitor an external s
witch and generate an event.
For more information on the sensor options, see the Sensor Configuration Page on the web interface.

To announce a device’s current IP address:
1. Press and release the RTFM button (see Figure 2-10) within a five second window.
Note The device will use DHCP to obtain the new IP address (DHCP-assigned address or default
to 10.10.10.10 if a DHCP server is not present).
Note Pressing and holding the RTFM button for longer than five seconds will restore the device to
the factory default settings.

When troubleshooting configuration problems, it is sometimes convenient to restore the device to a known state.
Note Each Intercom is delivered with factory set default values.
To restore the factory default settings:
1. Press and hold the RTFM button (see SW1 in Figure 2-11) for more than five seconds.
2. The device announces that it is restoring the factory default settings.
Note The device will use DHCP to obtain the new IP address (DHCP-assigned address or default
