8. ALARM ON/OFF SELECTOR
Switches alarm function on/off. NB alarm function is set to on position
upon activation of the monitor via power switch
DESCRIPTION OF THE ALARM FUNCTION
The alarm function is designed to automatically control picture
selection upon receipt of signals from alarm devices such as PIRS,
contacts or panic buttons, alert the operator and even trigger
additional equipment such as a time lapse VCR. Each camera
channel has an associated alarm trigger input. Irrespective of the
camera switching mode (ie Manual or Auto) the system will instantly
switch to the channel on which an alarm trigger has been received
and emit a warning sound for 15 secs. After this period allowing that
no further alarm triggers are received the system will automatically
revert to the mode in which it was originally set. Should additional
triggers be received during the 15 second period the system will
automatically switch to the relevant cameras and continue the
warning sound. At the time of trigger the system can also send an
output to external equipment such as a time lapse VCR in event
record mode or through an additional relay to lighting or alarm sound
etc. The alarm trigger device should be normally open. The alarm
output can be either normally open or normally closed.
