Shenyang emergency fire lighting Sometimes it is always on and cannot be turned off. There are many reasons for this phenomenon. The following are some possible reasons.
1. A capacitor in the fire emergency lamp was broken down, resulting in a short circuit. The solution is to repeatedly press the analog button on the emergency light panel. If it cannot be turned off, pull out the tripod socket of the double head emergency light.
2. There is a battery in the fire emergency lamp. When the circuit is faulty but the battery is not, the emergency lamp will be lit and discharged until the power is exhausted after the power supply of the lamp is unplugged.
3. When the mains voltage is very unstable, the electronic components of the lamps may be subject to strong high-voltage impact, resulting in the instantaneous high temperature of the electronic components and breakdown of the circuit. This phenomenon occurs mostly in the old national standard fire emergency lamps. The current fire emergency lamps and lanterns require new national standards, which is rare.
4. In case of failure of fire emergency lamps, professional personnel shall be available for maintenance, so as to prevent the fire emergency lamps from working normally in case of emergency.
The installation position of evacuation signs is proposed according to the building practices at home and abroad and the behavior habits of people in fire. The specific design can also be combined with the actual situation to reasonably select the installation location within the scope specified in the specification, for example, it can also be set on the ground. In a word, the signs set up should be easy for people to identify, conform to the habit of ordinary people to look ahead when walking, and can play a guiding role, but should be prevented from being blocked by smoke. For example, the evacuation signs set under the ceiling should consider a certain height from the ceiling.
At present, signs set in some places do not comply with the provisions of the current standard Fire Safety Signs GB13495, such as marking "evacuation door" as "emergency exit", "emergency exit" as "emergency exit" or "evacuation exit", and the direction of evacuation indication is confused. Therefore, it is necessary to clarify the setting requirements of these signs in the building.
