1.16 Optional Device Features186 Feature Guide1.16.10 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:KX-TDA30: An external relay device and DPH cardKX-TDA100/KX-TDA200/KX-TDA600: An external relay device, OPB card and EIO card• KX-TDA30 onlyThe 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.Installation Manual ReferencesKX-TDA302.5.1 DPH4 Card2.5.2 DPH2 Card2.9.1 Connection of Doorphones, Door Openers, External Sensors, and External RelaysKX-TDA100/KX-TDA2002.6.1 OPB3 Card (KX-TDA0190)2.6.4 EIO4 Card (KX-TDA0164)2.10.1 Connection of Doorphones, Door Openers, External Sensors, and External RelaysKX-TDA6002.8.1 OPB3 Card (KX-TDA0190)2.8.4 EIO4 Card (KX-TDA0164)2.12.1 Connection of Doorphones, Door Openers, External Sensors, and External RelaysPT Programming Manual ReferencesNone
