Proxima, Libra firmware ver. 2.12.xx
rev. 2.12.01
4.4.6 External devices control (I/O)
Apart from typical connection-related functions, Proxima / Libra PBX Server may
control other systems and external devices, thus becoming an important part of the
intelligent building system. It can control gates, furnace, lighting, sprinklers,
electric shutters, schoolbells etc. Privileged users may call the defined server
number(s), and after entering a special code, activate or deactivate previously
programmed device(s).
External devices may be also controlled according to the programmed schedule
(see: Common settings → External devices control (I/O) → Time control). For
example, the light can be periodically switched on and off in one or several rooms
to simulate someone’s presence in the building. If an external alarm system is
connected to the server, it may be also remotely activated or deactivated.
The full programming of external devices control is done in the computer program
(see: Common settings → External devices control (I/O)). You have 8 relays at
disposal in Proxima and Libra servers. The relays are located on the external
adapter, which is an optional equipment. The adapter serves to connect external
devices to Proxima IP PBX Server / Libra PBX Server.
The devices may be controlled by an extension user having relay access number
and activation/deactivation codes. If a trunk line works in DISA mode, the external
devices control is also available for external users, whose numbers have been
defined in the server as privileged to control external devices. A privileged user,
calling to the server from oustide, may dial the given relay access number during
the announcement. After hearing a confirmation tone – they activate or deactivate
the device by entering the required code on the phone keypad. For every command
separate codes may be defined in the computer program.
The external devices control may be also done by text messages sent from the
mobile phone numbers defined in the computer program. In order to control the
external device with a text message, send a following text message:
STERxy
where:
x: 1-8 output number,
y: 0-deactivation, 1-activation, 2-temporary activation.
Additionally, 8 automatic external devices activation/deactivation settings can be
defined in the server, e.g. a device may be activated on a defined hour on a selected
day(s) and deactivated on another.
