SST F120 - 8 Set the Time Delay for the Delayed Alarm Output; 9 Set the Latching Mode for the Delayed Alarm

120-32 January, 2016
Model F120 UV/IR Flame Detector
8. Set the Time Delay for the Delayed Alarm Output
The Model F120’s standard conguration requires at least two of its three sensors to be
activated to signal an alarm. When ame radiation is initially detected, the Alarm outputs,
both relay contact and current loop, are instantly activated. A red LED alarm light behind the
viewing window in the detector is also activated.
The detector has a default Delayed Alarm setting of 3 seconds to conrm a ame has been
detected. Should this ame persist for this period of time, the Delayed Alarm output (relay
and current loop) will be activated. The Delayed Alarm setting can also be changed from 3
seconds to 6 seconds to provide a rapid response time.
Default Setting
The factory default setting for the Time Delay for the Delayed Alarm Output is 3 seconds.
Switch # 3 Description
DOWN Sets the Delayed Alarm at 3 seconds
Changing the Time Delay for the Delayed Alarm Output
To change the Time Delay for the Delayed Alarm Output, follow the table below to adjust
the DIP Switch settings.
Switch # 3 Description
DOWN Sets the Delayed Alarm at 3 seconds (Default Setting)
UP Sets the Delayed Alarm at 6 seconds
9. Set the Latching Mode for the Delayed Alarm
The ame detector’s Delayed Alarm latching mode can be set as non-latching or latching.
Default Setting
The factory default setting for the Delayed Alarm is NON-LATCHING. This means that
when the detector no longer detects any re, the Delayed Alarm contacts will reset
automatically.
Switch # 4 Description
DOWN Sets the Delayed Alarm to NON-LATCHING. The Delayed Alarm
contacts will reset automatically when the ame detector no longer
sees any re.
