Description
The alarm function allows detecting a non-desired opening maneuver of the garage
door (thief, etc.). This function uses the closing mechanical limit switch as a sensor to
detect this non-desired opening maneuver.
Configuration
To enable the alarm function it is needed to configure any of the available outputs as
“Alarm” by means a VERSUS-PROG programming tool. The
P78
to
P90
configuration
parameters are used to configure the control panel outputs and the
PA1
to
PB0
configuration parameter are used to configure the TL-CARD-V extra outputs.
The configured “Alarm” outputs will be activated in case of non-desired opening
maneuver. Therefore these outputs can be used to activate any kind of alarm system.
The output is “normally opened” and it changes to “normally closed” when it is
activated. It keeps active until the alarm condition is resolved.
To use the alarm function a closing mechanical limit switch input is compulsory as the
mechanical limit switch is used as security sensor. Therefore it is needed to configure
any of the available inputs as mechanical limit switch input.
In order to use the closing mechanical limit switch, it has to be detected on the control
panel programming sequence. After programming the sequence it is possible to check
the detection result by using the status configuration parameter
P0A
. If this parameter
is set to ON it means that the closing limit switch has been detected.
Operating
If any output is configured as “Alarm” and a closing mechanical limit switch has been
detected in programming sequence, the control panel checks the closing mechanical
limit switch when the door is on the CLOSED position.
If manual or forced openings maneuver starts (motor is not activated by the control
panel) the closing mechanical limit switch will be released. In this case as the control
panel is still on the CLOSED position it detects the closing mechanical limit switch
release and it activates the “Alarm” outputs to inform about a non-desired maneuver.
