TESTING THE 555LS/557LS
DIP SWITCH 1– (Test Mode Enable)
Test mode allows the installer to properly test the 555LS/557LS
with the IEI 515
OR
517 G
LASS
B
REAK
S
IMULATOR
.
NOTE:
The 515 tester will test for basic operation of detector,
such as microphone response and proper alarm relay operation
, but it will not test for proper range. The 517 tester is required for
proper range verification.
Manual Test Mode with 515 or 517 Tester:
To enable test mode momentarily move DIP switch 1 from the
off position to the on position and then return it back to the off
position. The green LED will blink slowly. You have two
minutes to test the detector. Each time you trip the detector, indi-
cated by the green LED turning off and the red LED turning on
for three seconds, you will re-start the two minute test time
(
NOTE:
the red LED will not latch during test mode even if you
have DIP switch 2: alarm memory on). If you do not trip the
detector within the two minute test period, the detector will return
to normal glass break mode, indicated by the solid green LED.
To immediately return to normal glass break mode after the
detector is tested correctly, simply interrupt power for one sec-
ond.
Remote Test Mode with 517 Tester:
To test remotely with 517 tester move DIP switch 1 to the on
position. Step back about 10 feet from the detector and press
the tester “To Test” button. The detector should now enter test
mode indicated by the slowly blinking green LED. Position the
517 near the farthest point of the protected glass and point the
tester directly toward the detector. Close any curtains, drapes
or blinds and hold tester behind window covering to ensure
proper location of detector. Select the specific glass type and
size and push the appropriate key on the tester. Observe that
the unit trips consistently. When finished you can exit test mode
by pressing the tester “Test Off” button, interrupt power momen-
tarily or simply let the 2 minute test window expire.
NOTE:
With DIP switch 1 in the on position, test mode can
be entered remotely at any time with the 517 tester
NOTE:
Test mode does not prevent the 555LS/557LS from
detecting breaking glass.
INSTALLATION OPTIONS
DIP SWITCH 2– (Alarm LED Latch Mode)
• OFF–Red LED lights for 3 seconds on alarm and then
turns off.
• ON– Red LED will latch in memory upon an alarm.
Interrupt power or turn dip switch 2 off & on to reset.
DIP SWITCH 3– (Signature Supervision)
• OFF– Normal operation- without “Signature Supervision”.
• ON– Enables “Signature Supervision” processing.
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 frequen-
cies present from10 to40,000 cycles during a glass break
event. Signature Supervision monitors the input from the micro-
phone and the associated circuitry to insure that the unit contin-
ues to “hear” across the frequency spectrum. If, after120 hours
(5 days), the sensor has not heard the individual frequency ele-
ments associated with the signature frequencies within glass
break the amber LED will come on and stay latched to indicate
a potential trouble situation (
NOTE:
this does not trip the alarm
relay).When the detector has heard those particular frequen-
cies associated with glass break, the amber LED will reset.
Clapping, for example, will often produce the range of frequen-
