Chapter1Glassbreak/shock sensors 29 Application.
Retail shops in high-risk areas will often have roll-up metal shutters to protect glass windows at night. The clanging and banging sounds of these shutters can cause acoustic sensors to have false alarms. False alarms can also be caused by people rattling the shutters by or other sources of vibration.
Installation.
GS600 or 5150 shock sensors provide the best false alarm immunity on windows with roll-up shutters. The sensors mount on the glass ( Figure24 ) and are easily visible from the outside to deter break-ins. See Shock sensor testing on page8.If acoustic sensors are preferred, use the 5812, 2000, or 5820A sensors. Mount the sensor away from the street and roll-up shutters and within specified range limits. See Acousticsensor testing with the 5709C on page6.
