It is of practical significance to prevent family fires and reduce fire losses. In modern urban homes, many people are ignorant of family safety knowledge and cause fire accidents. This can cause well-being happy families to be destroyed in the blink of an eye. Fire, improper handling, and slow alarm are the main causes of casualties. Therefore, people should actively understand the main causes of home fires, master the knowledge to prevent fires, and protect themselves in the event of a fire, and eliminate them in time.
Smoke Alarms are suitable for fire alarms in homes, shops, dance halls, warehouses and other places. The fire process of fire is usually accompanied by three kinds of combustion products: smoke,
Heat and light. In the early stages of the fire, due to the low temperature, the substance is mostly in the smoldering stage, so a lot of smoke is generated. Smoke is one of the most important features of early fires. Smoke-sensing fire detectors are fire detectors developed using this feature and capable of responding to visible or invisible smoke particles. It is a device that converts the change in smoke concentration at the detection location into an electrical signal for alarm purposes.
How to buy:
(1) Install the
Smoke Alarm farther away from the cooking area. The smoke particles will become much weaker when they reach the alarm. If you choose this method, you should make clear the flow direction of the air. Otherwise, it will have no effect.
(2) Install a
Photoelectric Smoke Alarm. When a fire occurs that produces smaller particles, you may lose the opportunity for early warning, but you also save the hassle of multiple smoke alarms.
(3) Install an ion/opto-electric joint
Smoke Detector. If the two sensors are combined together, the sensitivity of the ion sensor can be set smaller, so that the device will reduce false alarms, and at the same time you can have a smoky fire that spreads quickly and a smoldering fire that spreads slowly. Larger sensitivity smoke alarm.
(4) Install an ion smoke alarm with mute function. In this way you can let the alarm reduce the sensitivity for 15 minutes, avoid harsh sounds when smoking or cooking.
Installation Precautions:
(1) The probe is mainly a detection element that contacts the combustion gas sensor. The platinum wire coil is coated with alumina and a binder to form a sphere. On the outer surface, platinum, palladium, and other rare metals are attached. Therefore, be careful when installing to avoid damaging the probe.
(2) The smoke alarm is a safety instrument, sound and light display function, and it should be installed in the place where the staff can easily see and hear, so as to eliminate the hidden trouble in time.
(3) The installation height should generally be 160-170cm, so that maintenance personnel can carry out routine maintenance.
(4) There must be no strong electromagnetic fields (such as high-power motors and transformers) that affect the operation of the instrument.
(5) The density of the gas to be measured is different, and the installation position of the indoor probe should also be different. When the measured gas density is less than the air density, the probe should be installed 30cm away from the roof and downward; otherwise, the probe should be installed 30cm away from the ground and upward.
