External Relay Control - Panasonic KX-NS700 Feature Manual

2.18.4 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 and a DPH2 card
•
The port of the DPH2 card to which the relay is connected must be assigned through system programming
as a relay port (not a door opener port).
•
Some devices may be unable to communicate correctly with the PBX. Confirm compatibility with the
manufacturer of a device before installing it.
•
Each external relay port has a COS assigned. This and the COS of an extension determine the extension
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 system
programming.
•
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.
