3.3.4.2 Setting of Delay Time
The flame detectors are equipped with Alarm delay option, which provides programmable
time delays by settings. The Alarm signal will be activated if the fire still exists after
programmed delay time. But the fire disappears within programmed delay time, the
detector will return to its standby state again.
The Alarm delay option affects the output relays and the 0-20mA. The LEDs and outputs
indicate warning levels during the delay time only if the fire condition exists.
