ES2545519T3 - Alarm trigger device for a security system - Google Patents

Abstract

Alarm trigger device (200) for a security system (10), comprising an interface (210) arranged to connect the alarm trigger device (200) to a management device (100) of the security system by means of of at least one wireless connection (50); trigger means (220) to trigger an alarm in case of predetermined event; power means (230) to allow the power supply of the alarm trigger device from a power source; communication control means (240) for detecting the absence of communication from the management device for a predetermined duration; and signaling means (250) for signaling said lack of communication at the level of the alarm trigger device.

These measures allow the manual trigger 200 to send information concerning its operating status to the monitoring center 100 in response to the interrogation signal sent by the monitoring center 100.

In a particular embodiment of the invention, the manual trigger 200 is equipped with a presence detector 260. The presence detector 260 is configured to emit a command signal to the mode signaling device signaling means 250 only they act in the presence of at least one person in the vicinity of the manual trigger 200. Such collaboration between the presence detector and the signaling means 250 makes it possible to prevent the implementation of the signaling means in the absence of a person in its vicinity, that could consume the little energy remaining in the power cell.

In this embodiment, in a first variant, presence detector 260 comprises an infrared ray detector to detect infrared rays from an associated infrared ray emitter. The absence or decrease of reception of the infrared rays coming from the emitter of the infrared rays would indicate the presence of one or several persons in the proximity of the manual trigger. In a second variant, presence detector 260 comprises an infrared ray detector to detect infrared rays from one or more persons in the vicinity of the manual trigger. The appearance of these infrared rays would indicate the presence of one or several people in the vicinity of the manual trigger.

The presence detector 260 may be integrated in the alarm triggering device 200 or it may be a device other than the alarm triggering device and associated with the alarm triggering device 200.

In a particular embodiment, the control processor may be configured to send a test signal to the monitoring center 100 and wait for a response signal from the monitoring center 100 in order to verify the wireless connection 50. A absence of response or reception of a response signal of a small intensity may indicate a wireless connection defect.

In another embodiment, the signaling means 250 may be configured to generate different signals based on a malfunction of the alarm triggering device 200. For example, the signaling means 250 may comprise a first warning indicator dedicated to a communication defect with the central monitoring and a second warning indicator dedicated to a power defect. Thus, the emission of a visible signal from the first indicator indicates a communication defect and the emission of a visible signal from the second indicator indicates a power defect. In variants, a single indicator can be configured to emit different colors depending on the malfunction or to flash with different frequencies depending on the malfunction. In other variants, the signaling means can emit a sound signal to warn of a malfunction. Different sounds may be emitted depending on the detected malfunction or the frequency of emission of these sounds may vary depending on the malfunction or these sounds may also be emitted in the form of pulses with repetition frequencies dependent on the malfunction.

As is evident and as on the other hand it is already apparent from the foregoing, the invention is not limited in any way to those of the modes of applications and especially considered embodiments; on the contrary, it encompasses all its variants without thereby departing from the scope of the invention as defined by the claims.

For example, although the embodiments have been described with a manual trigger, it is understood that in other embodiments of the invention, automatic fire detectors may be used.

In a variant and to avoid the implementation of the signaling device in the absence of a person in these surroundings, which could consume the little energy remaining in the battery, in the case where the person wanted to fire a fire alarm this would be informed that the trigger does not work and then could trigger the alarm through another manual trigger or otherwise.

In another variant of the invention, the radio connection between a trigger and the control panel can be made using intermediate triggers, which may allow the radio connection even if the distance between the triggered trigger and the control panel is too large to allow a direct connection. .
