Besides the above delays the alarm status is generated following an algorithm granting the filtering of false
alarms caused by any interference, air agent or casual short lasting flame.
The fourth jumper (MODE jumper) selects the functioning mode in accordance with the following table:
MODE FUNCTIONING MODE
yes with alarm storing (normal)
no without alarm storing (ON-OFF)
With the detector set on the normal functioning mode, the dector must be connected to a conventional
detection control panel.
When an alarm is detected, it will pulse. The supervided output line and always will activate the alarm relay to
reset the detector, operate a reset on the connected control panel
Resetting the corresponding detection board will reset the detector.
Setting the ON-OFF functioning mode the supervised output line is never activated (terminal block 3-4-5-6) and
when an alarm is detected the relay output is activated until the alarm condition is cleared.
When the alarm condition is cleared the detector will reset automatically until the next event. With this
functioning mode the iterated alarm output follows the detector status in an ON-OFF fashion.
When installing in non protected areas, given the high impendance of the sensitive device, the box must be
waterproof by waterproof wire pressing and a grommet under the front panel.
