Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a security monitoring system having a wireless test function, and more specifically, an operation test of a security monitoring system can be performed by transmitting a wireless signal. It particularly relates to one having a feature.

[Prior art] A security sensor such as a disaster prevention sensor or a security sensor provided in a dwelling unit is connected to a dwelling unit information panel, and when these security sensors issue an alarm, an alarm is issued from the dwelling unit information panel or a door phone handset. At the same time, a security monitoring system has been developed in which an alarm is transmitted from a house information panel to a centrally installed alarm monitoring panel.

FIG. 6 shows an example of such a system. The fire sensor S100 and the gas leak sensor S101 provided inside the dwelling unit H are connected to the house information panel 100 via signal lines l101 and l102, respectively. , The housing information panel 100 and the doorphone slave device 101 provided at the entrance are connected by a signal line l103,
Further, a signal line l104 derived from the house information panel 100 is connected to an alarm monitoring panel (not shown) provided at the center.

In such a security monitoring system,
For example, when a fire occurs and the fire sensor S100 issues an alarm, an alarm signal is transmitted to the house information panel 100 via the signal line l101, and the house information panel 100 receives the alarm signal and receives a signal from a speaker (not shown). Outputs an alarm sound and signal line l1
An alarm signal is transmitted to the doorphone slave device 101 via 03, and the doorphone slave device 101 receives the transmitted alarm signal and sounds and outputs an alarm sound from the speaker 101b. At the same time, an alarm signal is transmitted from the housing information panel 100 to the alarm monitoring panel side via the signal line l104, so that even if a resident is away, appropriate measures can be taken simultaneously with the occurrence of a fire. ing.

By the way, in such a system, when performing an operation test of the system, smoke or heat is added to emit a fire sensor S100, or gas is injected to emit a gas leak sensor S101. Although the method of confirming whether or not the warning notification is performed normally has been adopted, it is troublesome to add smoke, heat, or gas to the sensor, and depending on the environment in which the sensor is installed. Recently, test switches such as a micro switch and a magnet switch are installed inside each sensor because of danger, and these sensors are manually operated to perform a pseudo-alarm of each sensor to perform an operation test. An operation test has been developed to simplify the operation test.

In addition, in such a system, a test switch that can be operated by a tool such as a driver or a magnet on the door phone slave unit 101 so that the tester can perform an operation test from outside the house without entering the house. In addition to providing 101a, a signal line l100 is laid between the door phone handset 101 and the fire sensor S100 so that the fire sensor S100 can be simulated by operating the test switch 101a from outside the dwelling. In some cases, it is confirmed that an alarm sound is output to the doorphone slave device 101 via the house information panel 100, and the operation of the fire sensor S100 system and the wiring connection test can be performed.

However, in such a system, the fire sensor S100, the gas leak sensor S101 or the door phone slave 10
