Autonominis smūgio jutiklis UTC Fire & Security GS620N

The GS620N shock sensor offers a versatile solution for detection of forced entry through windows or doors. It can be mounted throughout a 360 degrees axis, vertically and horizontally, by ensuring that the brand logo is readable from left to right.

The GS620N is a latching and LED indicating stand-alone shock sensor which includes adjustable gross attack and pulse count sensitivity. It also features first-to-alarm and second-to-alarm LED indication and provides a selectable walk-test facility.

Its unique design enables the shock sensor to discriminate between a real break-in attempt and everyday background noise by measuring the shock frequency caused by the displacement in the protected structure.

The sensor is designed to activate (contact will open) when an acceleration greater than 1G is detected. This could be caused, for example by a strong blow, a high speed drill or sawing because the frequencies of these shocks fall within the sensors range of detection.

The analysing capability has two separate detection criteria: gross attack and pulse count. The gross attack threshold is designed to react to a single blow, while pulse count alarms when a pre-selected number of smaller shocks, occuring within a 30 second timing interval is reached. Both detection levels can be adjusted so that the installlation can be fine tuned to the environment and fully tested using the walk test facility. This digital signal processing is designed to eliminate false alarms and assure reliable detection of all types of attacks.
