Product Description
24V Relay Output LPCB Smoke Detectors 4 Wires Fire Sensor

24V Relay Output Lpcb Smoke Detectors 4 Wires Fire Sensor

AW-CSD381 is conventional photo-electronic smoke detector uses a state of-the-art optical sensing chamber. This detector is designed to provide open area protection and to be used with most conventional fire alarm panel.

The conventional rate of rise of rise heat detector uses thermal component to detect the temperature changing in the environment. It can enable fire alam when the temperature difference achieved the setting rate of rise temperature value reach the setting fixed ualue. It has a stable and reliable working performance.

Two LEDs on each detector provide local 360° visible alarm indication. They flash every six seconds indicating that power is applied and the detector is working properly. The LEDs latch on in alarm. LEDs will be off when a trouble condition exists indicating that the detector sensitivity is outside the listed limit. The alarm can be reset only by a momentary power interruption.

The detector that initiated the alarm condition will have its red LED and relays latched until reset by panel.
