External Relay Control - Panasonic KX-TDA100 Features Manual

When the call is answered, a special dial tone is heard, which continues until the user goes on-hook. If the
sensor call is not answered within a specified time, the call will be canceled. 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, the OPB card and EIO card
• 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.
• 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 outside
party), 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)

1.15.8 External Relay Control

Description
By 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 for
a preprogrammed length of time. When this timer expires, the relay turns off automatically. This gives the
PBX simple control over other equipment, allowing an extension user to, for example, activate an alarm from
his extension.
If the relay cannot be accessed (for example, because use is not permitted by COS, or the port is not in
service), a reorder tone will be heard at the extension.
Conditions
• Hardware Requirement: An external relay device, the OPB card and EIO card
