Abstract
The utility model relates to a fire alarm control system, which comprises a control host, a plurality of fire detectors and an alarm. The alarm is connected with the control host, the fire detectors are serially connected, both the first fire detector and the last fire detector are connected with the control host, and an annular circuit is formed among the control host and the fire detectors which are serially connected. If the circuit has a breakpoint, detection signals of each fire detector can be assuredly fed back to the control host timely, and accordingly safety level of the integral fire alarm control system is improved.
Description
Technical field
The utility model relates to a kind of fire alarm control system, belongs to the automatic fire alarm equipment technical field.
Background technology
In structural fire protection system and rail vehicle fire system, automatic fire alarm system is the important leverage of prevention and fire containment.In the prior art, fire alarm control system has generally comprised main control system, a plurality of fire detector and alarm, in each space that need survey, all places at least one fire detector; Main control system is connected with first fire detector; Be connected in series again between each fire detector, after one of them fire detector detects fire signal, can be with signal feedback to main control system; Send signal by main control system and give alarm, alarm equipment alarm.This Linear Control loop that prior art adopts exists not enough; Promptly when breakpoint occurring in the linear loop, the fire detector behind the breakpoint will be lost, and can't again fire signal be fed back to main control system; Thereby can't forecast fire alarm again, make whole automatic fire alarm system have potential safety hazard.
Summary of the invention
The utility model fundamental purpose is to address the above problem, and a kind of fire alarm control system is provided, and this system can guarantee that the detectable signal of each fire detector can both in time feed back, and then improves the safe class of whole fire alarm control system.
For realizing above-mentioned purpose, the technical scheme of the utility model is:
A kind of fire alarm control system; Form by main control system, a plurality of fire detector and alarm; Said alarm is connected with said main control system; Be connected in series between said a plurality of fire detector, first said fire detector all is connected with said main control system with last said fire detector, forms loop checking installation between said main control system and a plurality of said fire detector.
Further, said fire probe is smoke detector, heat detector or cigarette/temperature compound detection device.
Further, said alarm is display, phonetic alarm, hummer or acoustic-optic alarm.
Content to sum up; The described a kind of fire alarm control system of the utility model; With forming loop checking installation between main control system and a plurality of fire detector; If occur breakpoint in the loop, can guarantee that still the detectable signal of each fire detector can both in time feed back to main control system, and then improve the safe class of whole fire alarm control system.
Description of drawings
Fig. 1 is the utility model structural representation.
As shown in Figure 1, main control system 1, alarm 2, fire detector 3.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As shown in Figure 1, a kind of fire alarm control system is made up of main control system 1, a plurality of fire detector 3 and alarm 2.In buildings or rail vehicle, at least one fire detector 3 is all placed in each space that need survey, to guarantee not having safe dead angle.Fire probe 3 can or be cigarette/temperature compound detection device for smoke detector, heat detector.
Wherein, Link together through a pair of cable between a plurality of fire detectors 3; First fire probe 3 all is connected with main control system 1 with last fire detector 3 in a plurality of fire detectors that are connected in series each other; Be equivalent to, form loop checking installation between main control system 1 and a plurality of fire detectors 3 of connecting.If breakpoint occurs in a certain place in the loop; Can guarantee that still the fire detector 3 behind the breakpoint do not lose; Detector 3 states of opposite side through loop checking installation after with breakpoint flow to main control system 1; And then the level of security of detector 3 hard-wired returns brought up to SIL 2 by SIL 1, reliability has improved about 10 times.
As stated, in conjunction with the given scheme content of accompanying drawing, can derive the similar techniques scheme.In every case be the content that does not break away from the utility model technical scheme, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of the utility model technical scheme according to the technical spirit of the utility model.
Claims (3)
1. fire alarm control system; Form by main control system, a plurality of fire detector and alarm; Said alarm is connected with said main control system; Be connected in series between said a plurality of fire detector, it is characterized in that: first said fire detector all is connected with said main control system with last said fire detector, forms loop checking installation between said main control system and a plurality of said fire detector of connecting.
