product description :

Alarms using photoelectric or ionic smoke sensors are stable and reliable, and their performance is far superior to fire alarms of gas-sensitive resistors. This alarm can be used to make timely alarms on the smoke from various early fires. The product is small and compact, and it can organically combine wireless transmission and fire smoke sensors. When used alone: first fix its installation base on the ceiling of the hall to be monitored, connect the battery to this alarm, and then screw it into the installation base. In the working state, once the smoke concentration and duration in the guard space reach the alarm value, the buzzer will sound immediately. When matching with the wireless anti-theft alarm system: the installation and use are the same as those used alone. When the alarm is alarming, it will also transmit a wireless signal to the wireless anti-theft alarm host at the same time. The alarm host will respond to the alarm whether it is in the armed or disarmed state (more The ringing siren sounds and automatically dials the preset phone alarm at the same time). With this method of use, the alarm range is wider, and when there is no one in the house, the fire alarm can be grasped in time, so that the alarm can be given at the first time.

Features:

◆ Photoelectric detection method ◆ Ceiling installation ◆ Optical Labyrinth ◆ Adopt low power consumption CMOS microprocessor ◆ Special moisture-proof design ◆ Independent/Wired network/Wireless output method (optional) ◆ With manual test function ◆ Stable and reliable working performance ◆Single-sided PCB process ◆Using ultra-thin structure design ◆ Unique structural design, dust-proof, insect-proof, and anti-interference from external light

Product installation:

1. Please connect the battery with the battery buckle, install it in the battery box of the product, keep the battery powered, and the product enters the normal working state. 2. When the power is turned on, the detector directly enters the normal monitoring state. The indicator light flashes once every 40 seconds. When in the alarm state, the indicator light flashes once every second. 3. Choose a suitable location, generally installed on the ceiling in the center of the detection space, use the installation screws to fix the base to the selected installation location, snap the detector in, rotate it and check whether it is firm. 4. After the product is installed, press the test button to test whether the product is working properly and whether the buzzer sounds.

Testing method:

First, after installing the battery, the first is to directly press the test button on the smoke sensor, and the alarm will be directly triggered. The second is to smoke, and then the hole facing the smoke sensor on the side is continuously sprayed into 3~4 mouths, and the smoke should not be too thin. After a while, the indicator light on the smoke detector will start flashing, and after a while, an alarm sound will sound.

Precautions:

1. This product should not be installed in an environment that is extremely cold and hot, with extremely high wind speeds, and where a lot of smoke and dust are often present. 2. The product should be tested once a month. 3. In order to ensure the smoke sensitivity of the product, the surface of the detector needs to be cleaned with a soft brush every 6 months, and the power must be disconnected before cleaning. 4. When the battery voltage is insufficient, the buzzer will emit a short beep every 40 seconds. To ensure the detection sensitivity of the detector, please replace the battery in time.
