Will the hotel fire hydrant light a red dot?

Hotel fire hydrants will be lit with red dots. A red light indicates an alarm. If there is smoke or dust in the house, the detector will give an alarm.

Fire sprinkler: a sprinkler that starts automatically within a predetermined temperature range under the action of heat, or is started by control equipment according to fire signals, and sprays water according to the designed sprinkler shape and flow. This is part of the sprinkler system.

The detectors of general manufacturers flash every few seconds during normal detection (red light and green light), and the indicator light will always be on in case of fire or pollution. Automatic fire alarm detectors are generally smoke detectors. Flashing is normal, and its status should be displayed on the main engine of the fire controller on the first floor.

Fire linkage control means that after the fire detector detects the fire signal, it can automatically cut off the relevant air conditioners in the alarm area, close the fire damper on the pipeline, stop the ventilator and open the smoke exhaust valve on the pipeline.

Automatically close the electric fire doors and fire shutter doors in the relevant parts, cut off the non-fire power supply in turn, turn on the emergency lighting and evacuation sign lights, stop all elevators except the fire elevators, and immediately start the fire extinguishing system to extinguish the fire automatically through the controller in the control center.
