Fire hazard safety warning device

The utility model relates to a fire hazard safety warning device, in particular to a safety warning device installed in a building and provided with photoelectric marks. Tri-phosphor lighting tapes are installed at positions from all passages for entering indoors to entries, and thermal radiation switches are installed at two ends of each passage and connected with the input ends of a programmable controller through couplers and interface circuits. Air-sensitive sensors are also connected with the input ends of the programmable controller through amplifying circuits and driving circuits, and all output ends of the programmable controller are correspondingly connected with the tri-phosphor lighting tapes, a sound warning device and a wireless global system for mobile (GSM) remote warning device. The fire hazard safety warning device can supply human traffic indication of all emergency exits and fire fighting accesses through colors of flashing marks of the tri-phosphor lighting tapes and flash frequency change, sends sound warning and is accessed into a communication base station in wireless mode to give alarms to fire departments.
