Product description

In recent years, various types of fire equipment can not fire normal operation of the fire cases are not uncommon, the fire department in the daily fire inspection found in the absence of fire equipment are also numerous, many experiences and lessons have proved that the fire alarm is timely and accurate and One of the important prerequisites is whether the fire fighting equipment can play a role, and the fire fighting equipment power supply is a fundamental problem to ensure the normal work of the fire equipment.

Building fire safety depends largely on the quality of fire equipment, and whether the fire equipment can work properly depends on the work of the power supply status. Because the fire fighting equipment power does not work: fire pump does not start, resulting in fire water, can not put out the fire; fire partition led to fire shutter and fire door can not in place, can not control the spread of fire; exhaust fan does not start smoke, smoke The elevator can not work; evacuation instructions and emergency lighting can not be assisted evacuation, so that the safe evacuation of the fire can not be carried out, leading to serious disastrous consequences. If there is no reliable fire power equipment, put a lot of money building fire facilities in the fire in name only, it must pay attention to the continuous supply of fire power equipment.

Design of fire equipment power supply monitoring system can effectively reduce the failure rate of fire power supply equipment to ensure the normal work of fire equipment in order to fire in the fire equipment under normal operation, evacuation and rescue personnel to provide strong technical support, fire equipment Power monitoring system will become the "patron saint" of fire protection equipment to play an effective role in safeguarding people's lives and national property security.

System components 

System by the state of the fire control equipment power supply, voltage and current signal sensors, power signal relay box, system bus assembly.

system applications:

By the signal sensor to collect line signal, sent to the fire equipment power status monitor. Voltage, current and working status of the main and standby power supply of the fire-fighting equipment and judge whether the power supply of the fire-fighting equipment is interrupted, overvoltage, undervoltage, overcurrent, short circuit, phase or fault.

SMGDY-Z power signal relay box product overview

Power signal relay box is the main component of the fire control equipment power monitoring system, when the number of power supply sensors more than 64 or more than 500 meters away from the power supply for the subsequent power supply sensor. Relay power box timing automatic power supply status and real-time display, you can work through the two bus to upload the power monitor or monitor the host, easy to manage.
