Abstract
The utility model belongs to a fire monitoring device, which is composed of a junction box, temperature sensitive wires, and a terminal box. The temperature sensitive wires are two zinc coated steel wires whose surface is covered with insulation material of low-melting-point and is hinged with each other. The tail end of the temperature sensitive wire is connected with the terminal box, and the head end of the temperature sensitive wire is connected with the alarm by the junction box. The fire monitoring device can realize monitoring of long range and large area to fire scenario. The utility model has the advantages of high sensitivity, safety, low cost, humidity proof, and corrosion resistant.
Description
The utility model belongs to the fire monitoring device.
For departments such as some power stations, warehouses because site environment, be easy to produce the overheated fire that causes, and still do not have so far a kind of highly sensitive, dependable performance, the protection area is big, can be along very long temperature sensing fire pick-up unit apart from continuous probe.
The purpose of this utility model provides a kind of highly sensitive, can grow the fire detecting arrangement of the range surveillance condition of a fire.
Technical essential of the present utility model is: it is made up of terminal box, heat-sensitive line, termination box three parts, heat-sensitive line is that the surface is surrounded by the low melting point insulating material, and line is incorporated into two galvanized steel wires together, its pitch is 25～55mm, the end of heat-sensitive line connects termination box, manual examination (check) button and light emitting diode are arranged on the termination box, can whether normally check that the head end of heat-sensitive line links to each other with alarm through terminal box detector operation.When condition of a fire danger occurring, two steel wires contacts of heat-sensitive line, 24 volts of level that alarm provides directly send terminal box, make the interior stabilivolt of its box puncture, the bright warning of light emitting diode, the device of simultaneously electric signal being delivered newspaper sends sound and light alarm.
The utility model is applicable to place and open-air installation that environment such as power station, cable tunnel, warehouse, stacking are comparatively abominable, can realize the large-area monitoring of long distance to the condition of a fire.Have highly sensitively, safe and reliable, cost is low, humidity, advantage such as anticorrosive.Its advanced design, reasonable, easy to utilize.
