Alarm - Tait TB8100 User Manual

IF Counter at maximum (LightTrigger) THEN Activate Digital
Output 2.
See "Base Station that Controls Landing Lights" on page 195.
Deactivate Digital Output n
The Deactivate Digital Output n action makes the Digital Out n line on
the system interface inactive. If this line does not exist on the current user
interface, the action has no effect.
In base stations with a complex set of Task Manager tasks, you need to
understand exactly how this action works. The actual deactivation of the digital
output doesn't happen till the end of a processing cycle. So the task list can
activate and deactivate a digital output many times, but the output line will only
ever be deactivated if the last action for that digital output is to deactivate it.
Tx Relay actions
Tx relay override actions can enable, disable, or toggle the Tx Relay system
flag. This gives you an additional layer of control over the Tx Relay Driver line
on the system interface. When the base station enters Run mode, the flag is
enabled.
When the Tx Relay system flag is disabled, the Tx Relay Driver line cannot go
active.
When the Tx Relay system flag is enabled, the base station can control an
antenna relay using the Tx Relay Driver line, switching the relay before
powering its transmitter up.
If the base station is not fitted with a system interface board that provides a Tx
Relay Driver line, the Tx Key system flag has no effect.
