1.15 Optional Device Features114 Feature Guide• After a sensor has been activated, the PBX will ignore any further alerts from the same sensor for theduration 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 areignored.• The assigned sensor name and/or number are shown on the display of PTs and PSs when a sensorcall is received.• If the destination of a sensor call has set FWD, the sensor call will be redirected to the FWD destination.However, if the FWD destination is not supported as the destination of a sensor call (e.g., an outsideparty), the call will be received at the original destination. (→ 1.3.1.2 Call Forwarding (FWD))• The following features cannot be used when a sensor call is received:– Alternate Receiving—Voice (→ 1.5.3 Intercom Call)– Hands-free Answerback (→ 1.4.1.4 Hands-free Answerback)– Consultation Hold/Call Hold (→ 1.12.1 Call Hold)– Call Transfer (→ 1.11.1 Call Transfer)– Executive Busy Override (→ 1.7.2 Executive Busy Override)– Remote Extension Control by User (→ 1.23.5 Remote Extension Control by User)• Sensor call information is output on SMDR.Installation Manual References2.5.1 DPH4 Card2.8.1 Connection of Doorphones, Door Openers, External Sensors, and External Relays1.15.9 External Relay ControlDescriptionBy turning external device relays on and off, the PBX can control external devices such as alarms.When an extension user enters the External Relay Control feature number, the specified relay turns on fora preprogrammed length of time. When this timer expires, the relay turns off automatically. This gives thePBX simple control over other equipment, allowing an extension user to, for example, activate an alarm fromhis extension.If the relay cannot be accessed (for example, because use is not permitted by COS, or the port is not inservice), a reorder tone will be heard at the extension.Conditions• Hardware Requirement: An external relay device and the DPH card• The port of the DPH4 card to which the relay is connected must be assigned through systemprogramming as a relay port (not a door opener port).• Some devices may be unable to communicate correctly with the PBX. Confirm compatibility with themanufacturer of a device before installing it.• Each external relay port has a COS assigned. This and the COS of an extension determine theextension users who can use External Relay Control.• The length of time that a relay is turned on can be specified separately for each relay through systemprogramming.• If the same or another extension tries to access an external relay that has already been switched on,the timer for that relay is reset.
