A fire alarm device with a safety lock

Abstract

The invention provides a fire alarm device with a safety lock, which includes a box body, a bracket and a warning light. One side of the box body is welded with an outer plate, and both sides of the box body are provided with mesh holes. The bottom of the box body is bonded with a lens, the inner side of the box body is installed with a smoke alarm through bolts, the inner side of the outer plate is clamped with an inner plate, and one side of the inner plate is clamped with a fan tube, and the fan tube A fan is installed on the inner side of the inner plate through bolts, a motor is installed on one side of the inner plate, and a main shaft is installed on one side of the motor. The fire alarm device with a safety lock can prevent false alarms and increase the smoke The sensitivity of the alarm can avoid the decline in the sensitivity of the smoke sensor, improve the reliability and sensitivity of the alarm, prevent the flame from entering the box, and avoid the smoke alarm being burned out by the flame when a small fire occurs, so as to ensure the safety of the smoke alarm. Safety, to ensure that the alarm mechanism can be reused, and it is suitable for fire alarms in building interiors.

Description

technical field [0001] The invention relates to the technical field of fire alarm equipment, in particular to a fire alarm device with a safety lock. Background technique [0002] In order to ensure the safety of personnel and property in the building, it is often necessary to install fire alarm equipment in the building, which can quickly carry out alarm work in the event of a fire. The existing fire alarm equipment is basically light in weight, small in size and easy to install. , high working stability, low working energy consumption, high sensitivity to fire triggering, long service life, etc., can meet the needs of rapid alarm for fires in the building. However, for the existing fire alarm equipment, On the one hand, dust and smoke cannot be effectively distinguished when alarming, making the smoke alarm easy to cause false alarms due to dust accumulation, reducing the reliability of the alarm; on the other hand, when a fire occurs, it is easy to cause fire hazards The...

[0002] In order to ensure the safety of personnel and property in the building, it is often necessary to install fire alarm equipment in the building, which can quickly carry out alarm work in the event of a fire. The existing fire alarm equipment is basically light in weight, small in size and easy to install. , high working stability, low working energy consumption, high sensitivity to fire triggering, long service life, etc., can meet the needs of rapid alarm for fires in the building. However, for the existing fire alarm equipment, On the one hand, dust and smoke cannot be effectively distinguished when alarming, making the smoke alarm easy to cause false alarms due to dust accumulation, reducing the reliability of the alarm; on the other hand, when a fire occurs, it is easy to cause fire hazards The alarm equipment is burnt out by the heat absorbed, which is not conducive to ensuring the safety of the fire alarm equipment when the fire is small. On the other hand, when the personnel alarm through the manual alarm device, it is often necessary to break the safety lock and then open the alarm switch to ensure safety. are destroyed, which is not conducive to reuse and alarm elimination
