Problems solved by technology

[0002] The fire emergency lighting lamps are controlled by ordinary single-control switches. Even if the reliability of the power supply of the power distribution system is guaranteed, when the switch is turned off, the lamps are extinguished.
At this time, once a fire accident occurs, the emergency lighting system lamps cannot be normally lit, and the emergency evacuation of personnel in the event of a fire and the normal use of backup lighting for firefighters and places that need to continue working in the building cannot be guaranteed.

Abstract

The invention discloses a fire emergency lighting control circuit. The fire emergency lighting control circuit comprises a fire alarm output linkage control contactor, wherein the fire alarm output linkage control contactor comprises a fire automatic alarm linkage output contact and an intermediate relay contact part; the fire automatic alarm linkage output contact is controlled by a control module and an intermediate relay; one end of the control module is connected with a loop bus and a power bus, and the other end of the control module is connected with the intermediate relay; and the intermediate relay contact part can be communicated with a plurality of alternating current contactors. According to the fire emergency lighting control circuit, when a fire occurs, an emergency lighting lamp can acquire power from an emergency lighting distribution box regardless of the state of an emergency lighting lamp control switch, so that the emergency lighting lamp can be instantly turned on for fire emergency. A requirement on illumination for people safe evacuation during the occurrence of the fire is met, and the working illumination of a working scene on which firefighters continuously perform rescue operation during the occurrence of the fire is ensured.

Description

technical field [0001] The invention relates to the technical field of control circuits, in particular to a fire emergency lighting control circuit suitable for starting emergency lighting in emergency situations. Background technique [0002] The fire emergency lighting lamps are controlled by ordinary single-control switches. Even if the reliability of the power supply of the power distribution system is guaranteed, when the switch is turned off, the lamps go out. At this time, once a fire accident occurs, the emergency lighting system lamps cannot be normally lit, and the emergency evacuation of personnel during a fire and the normal use of backup lighting for firefighters and places that need to continue working in the building cannot be guaranteed. Contents of the invention [0003] The purpose of the present invention is to provide a fire emergency lighting control circuit that can obtain power from the emergency lighting distribution box to ensure that the emergency...
