2.18.3 External Sensor
Description
External sensing devices, such as security alarms or smoke detectors, can be connected to the PBX. When
the PBX receives input from a sensor, a call is made to the preset destination, alerting the extension user.
The available destinations of a sensor call are as follows:

When the call is answered, if distinctive dial tones are enabled, dial tone 3 is heard, and continues until the
user goes on-hook. If the sensor call is not answered within a specified time, the call will be cancelled. It is
possible to set a different ring tone pattern for calls received from each external sensor, to distinguish between
them.
Conditions
• Hardware Requirement:
An external sensor and a DOORPHONE card
To connect an external sensor to a legacy gateway (® 5.3.1 Stacking Connection), refer to the
documentation of the legacy gateway.
• Some devices may be unable to communicate correctly with the PBX. Confirm compatibility with the
manufacturer of a device before installing it.
• After a sensor has been activated, the PBX will ignore any further alerts from the same sensor for the
duration specified by a timer. This timer can be set separately for each sensor.
• As long as the previous sensor call is still being performed, any further alerts from the same sensor are
ignored.
• The assigned sensor name and/or number are shown on the display of PTs and PSs when a sensor call
is received.
