PRE-TESTING THE TRI-GARD 555LS/557LS
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 517 Glass Break Simulator is required to perform
this test.
WARNING:
The 555LS/557LS detector has been designed to detect
glass break within a specified range from the glass–(25' for
plate, tempered,and wired glass glass and 20' for laminated
glass).You should not extend past these rated ranges for any
reason. Acoustics of different areas can artificially extend the
range of the tester.
1) Connect a 9Volt DC alkaline battery or 12 VDC power
source.
2) Proceed to section: Testing the 555LS/557LS
NOTE: the red LED will flash slowly indicating low voltage
(input voltage <10VDC) and also the relay will not be ener-
gized (common and normally closed will be open).
