HW-F220 HaiWang Direct-insert civilian fire alarm

I. Fire Alarm User Manual

TheHW-F-220 is a 220V plug-in civilian fire alarm. It uses a dual-band infrared 2-in-1 flame sensor with a Curie temperature detection method, employing lithium tantalum crystal material. It detects combustion of materials with flame temperatures exceeding 250-4000℃, exhibiting a significant temperature difference and high-contrast polarity change, triggering an alarm signal. The detector is stable; when a fire occurs in the detection area, the alarm can quickly detect and respond within 10 seconds, triggering an audio alarm. It is used for fire detection in small indoor spaces and for various open flame detection fire warnings: fire alarms, chemical combustible material alarms, residential fire detection, equipment and machinery fire detection, etc.

II. User Manual

1. 220V switching power supply transformer plug-in power supply.

2. Wait for the fire alarm to self-test and power on: Welcome to HaiWang Fire Alarm. This product is for fire detection; please place it in a socket for wall-mounted installation.

3. After the power-on voice announcement, it enters fire detection mode.

After the power-on voice announcement ends, the blue breathing light indicates Sentinel mode, which is the fire alarm detection time. When the trigger condition is met, the system will continuously output a trigger signal as long as the fire persists, indicated by a constantly lit red LED. When the flame disappears, the flame sensor source will reset in approximately 30 seconds, returning to Sentinel detection mode. This sensing time is determined by the occurrence of a fire.

1. Avoid installation in areas with heavy steam/oil fumes, such as kitchens and bathrooms, and keep away from air conditioner vents and dust accumulation areas to prevent false alarms.

2. Clean the optical sensor's sensing surface with a soft brush quarterly to prevent dust from obstructing detection accuracy.

3. Monthly, press the ignition test button to check the audible and visual alarms and power connection to ensure timely response in case of fire.
