ZX Fire Alarm Control Panels
•
These alternative thresholds are programmed to operate only at certain times of the day and at all
other times the thresholds will return to normal.
This facility is very flexible. It should only be used in certain specialized applications and
with great care. The default mode is for all detectors to default to the manufacturer's
recommended alarm level.

•
Press 'Yes' to accept and step on. Press 'No' to change and then enter the required end time using
the number buttons.
There is no restriction on the range of times entered. Any special pre-alarm and fire alarm
values entered for the devices will then be used within the specified period.
11.4 Verification Mode
•
Alarm verification can be used to reduce false alarms by placing a delay on a transient alarm signal
received from a smoke detector. This delay time can be set when commissioning the panel.
•
When an alarm is first received from a smoke detector the panel will start an internal timer and attempt to
reset the detector. If the detector is still in alarm after the verification timer has expired the control panel will
go into alarm. If the detector is not in alarm at this point, the panel will enter a 60-second Confirmation
period. Any alarm received during the confirmation period will then be deemed a genuine fire alarm.
