The IMPAQ Glass Break detector can be used for the detection of breaking glass; it is manufactured by the TEXECOM. It is a digital acoustic glass break detector with digital sound processing, designed for sheet, laminated, hardened, tempered, wired glass with a thickness from 2.4 to 6.4 mm.

The sensor analyzes four different frequency ranges (frequency, amplitude, time sequence), which ensures high resistance to false alarms.

The false alarm immunity is enhanced by using the Flex technology, which represents an analysis of low frequencies caused by bending the glass sheet at the beginning of the destruction. An alarm is only triggered when an evaluated bending is immediately followed by the sound of shattering glass. This eliminates false alarms, e.g. when a glass object is broken in the interion (such as a glass).

Exact information on the assembly, correct setting and the parameters is stated in the product operating instructions.

Notes:

  1. The example shows the connection of the detectors loop as double balanced; the ALARM and TAMPER outputs in the detectors must be correctly connected with 1 k resistors (see the general description of double balancing in Chap. 8.1.1).

  2. Correct installation of the detector is specified in the product operating instructions.

  3. The detector's power consumption from the 12 V supply is typically 11 mA.

  4. A cable with the wire diameter of at least 0.3 mm can be used for the connection, e.g. the SYKFY cable; its length can be up to dozens of meters.
