Abstract
The utility model discloses an alarm apparatus, comprising an alarm main body, a power switch, a power light, a cancel switch, an alarm relay, a cancel relay, an alarm button, an alarm light, and an alarm sound. A housing of the alarm main body is provided with the power switch, the power light, and the cancel switch. The alarm relay and the cancel relay are disposed in the housing of the alarm main body. The alarm button, the alarm light, and the alarm sound are disposed outside the housing of the alarm main body. The alarm apparatus is advantaged by simple structure, reliable operation, and timely alarm, and is suitable to be used in independent small-size places (for example, a small-size store, etc.).
Description
Technical field:
The utility model relates to a kind of alarm, belongs to the burglar alarm technical field.
Background technology:
At present, the shortcoming of common alarm on market: principle of work, product structure complexity; Price is high; Poor reliability, easily misoperation, small-sized shop front shop have the position independently, and the staff is few in the shop, the characteristics that the business hours are long, if adopt at present some large-scale alarms, cost is too high, is not suitable for independent small-sized place use.
The utility model content:
The purpose of this utility model be to provide a kind of principle of work reliable, simple in structure, easy to use, flexibly safely, be convenient to promote alarm.
The utility model is implemented by following technical scheme: a kind of alarm, and it comprises alarm body, power switch, power light, cancel switch, alarm relay, releasing relay, alarm button, alarm lamp and alarm sound; Wherein, be provided with described power switch, described power light and described cancel switch at described alarm body housing; Be provided with described alarm relay and described releasing relay in described alarm body enclosure interior; Be provided with described alarm button, described alarm lamp and described alarm sound in described alarm body outside; Described alarm button in parallel and one group of normally opened contact and one group of normally closed contact of described releasing relay, the coil of described alarm relay of described alarm relay are composed in series warning circuit; Another group normally closed contact of another group normally opened contact of described alarm lamp in parallel and described alarm sound and described alarm relay, described releasing relay is composed in series the chimes of doom optical circuit; The coil of described cancel switch and described releasing relay is composed in series relieving circuit; Described power light, described warning circuit, described chimes of doom optical circuit and described relieving circuit in parallel are connected with described power switch.
It also comprises test switch and test relay, and the normally opened contact of described test relay is in parallel with another group normally opened contact of the described alarm relay of described chimes of doom optical circuit; The coil of described test switch and described test relay is composed in series hookup; Described hookup is in parallel with described power light, described warning circuit, described chimes of doom optical circuit and described relieving circuit.
Described cancel switch is key switch.
Advantage of the present utility model: simple in structure, reliable operation, product price be low, be convenient to promote; Installation, easy to use, alarm body, alarm button, alarm lamp and alarm sound can be distinguished hidden layout, have dirigibility, security; Report to the police reliable, behind the button that pushes for emergency, even alarm button is damaged, alarm is Normal Alarm still; Have test function, but the running check alarm guarantees the normal duty of alarm; Alarm release need could be removed by key switch, has guaranteed the reliability of reporting to the police; Report to the police in time, be applicable to independent small-sized place (such as small-sized shop front shop etc.) and use.
