Function:

Self check: Press the detection button,detectorLEDAlways on, while sending out a report

Police sound system(Note: Self inspection only tests the internal functions of the detector itself,

Relay signal output during self check).

APayment work: Under normal circumstances,The detector is approximately every 6 The second indicator light will flash once. The detector automatically detects the smoke concentration in the surrounding environment,And automatically compensate for sensitivity based on the usage environment conditions. When the smoke concentration approaches the alarm value, the detector accelerates the intelligent calculation of the smoke concentration trend,At the same time, the alarm indicator light starts flashing. If the calculation result reaches or exceeds the alarm value,The detector begins to sound and light an alarm. When the smoke concentration in the surrounding environment drops below the alarm value,The detector automatically returns to normal working condition. When the on-site temperature of the detector reaches 57 After the temperature drops, the detector indicator light starts flashing when the temperature on site is below 57 The synchronous detector automatically returns to normal working condition

BWork: Under normal circumstances, the detector operates approximately every6The second indicator light will flash once, and the detector will automatically detect the smoke concentration in the surrounding environment and compensate for sensitivity based on the usage environment status. When the smoke concentration receives the alarm value, the detector will accelerate the intelligent calculation of smoke and at the same time adjust the temperature of the on-site environment

Degree detection, when the smoke concentration and temperature on site reach57After the temperature is reached, the detector indicator light begins to flash and an alarm signal is output. Output: Passive Contact Output: Contact Capacity24V/1A, can be set to normally open or learn point closed contact output by detecting the internal route along the way. The route is set to normally open by default when leaving the factory
