The red light flashes in the hotel exhaust fan.
This is a fire sprinkler.
The flashing red light in the hotel exhaust fan is generally not a sneak shot device, but a fire-fighting device: a fire sprinkler. A flashing red light indicates normal operation.
The fire sprinkler used in the fire sprinkler is started by itself under the action of heat according to the preset temperature range, or by the control equipment according to the fire signal. If the temperature exceeds the preset temperature, the sprinkler begins to spray water, which is part of the sprinkler system.
