TRI-GARD 550/552LS SIGNATURE SERIES

The Signature Series

™

Tri-Gard is the first audio glassbreak

detector with microprocessor based, multiple signature

analysis. The detector filters amplitude components of sound

so that it can process all sounds at the same volume and

eliminate the need for sensitivity adjustments. This gives

maximum detection accuracy even in muffled (i.e.curtains,

shades, blinds, small glass sizes) glassbreak applications.

Through advanced signature analysis, common false alarm

sources are filtered out, while providing for the best

glassbreak detection.

TRI-GARD 550/552LS FEATURES

• Specified for plate, wired, tempered & laminated glass

• Microprocessor-based for better discrimination

• Multiple Signature Analysis

• Signature Supervision

• Omnidirectional sensitivity

• No sensitivity adjustments

• Environmental switch feature

TRI-GARD 550/552LS APPLICATIONS

• Glassbreak protection in residential, commercial

and industrial areas

• Protects plate, wired, tempered & laminated glass

• Omni direction detection to protect multiple windows

• Areas with closed drapes or blinds will reduce range.

Test with 515 tester for specific range

• Wall or ceiling mount installations

range of the detector by 50%. Since room acoustics and window coverings can

vary considerably, all detector installations should be checked with the 515 tester.

PAGE 2
MOUNTING LOCATIONS The Tri-Gard can be mounted on any type of ceiling or wall. For best false alarm immunity the detector should be mounted at least 4’ from the glass to be protected and from noise sources such as kitchen sinks, stereos, television, etc. For maximum performance install the detector in direct line of sight to all glass that you are protecting. CEILING MOUNTING Mount the 550/552LS in any location on the ceiling which is in direct line of sight of the glass to be protected.

550LS CIRCUIT BOARD NOTE: Tamper spring is in hardware package with screws 552LS CIRCUIT BOARD SIGNATURE SUPERVISION™ Using a microprocessor enables the detector to process more data to make better decisions in determining a glass break event and also provide more information back to the user regarding the operating status of the device. A glass break event occurs over a broad frequency range. There are frequencies present from 10 to 10,000 cycles during a glass break event.

PRE-TESTING THE TRI-GARD 550/552LS FOR DESIRED LOCATION Pre-testing of the detector prior to final installation can be performed to ensure that the detector is installed in the proper location with respect to all glass being protected. The IEI 515 Glass Break Simulator is required to perform this test. WARNING: The 550/552LS detector has been designed to detect glass break within a specified range from the glass–(30' for plate glass and 25' for tempered, laminated and wired glass).
