Sensitivity is too low
Increase the sensitivity setting
In order to ensure reliable operation, use “Glass checker EG-2000” (sold separately), and check operation and sensitivity according to the following
description. *Follow the instruction manual of the glass checker.
(4) If you activate the checker from the glass surface most distant to the
sensor unit, and only the environmental indicator lights up, the sensitivity
is normal. If the environmental indicator does not light up, the sensitivity
is too low. On the contrary, if it lights up and the alarm indicator also
lights up, the sensitivity is too high. If there are positions where the
sensitivity is not appropriate, check the operation area again, or adjust the
sensor sensitivity.
SENSITIVITY CHECK
Check the extension of the detection area, and the most appropriate sensitivity while checking that the environmental indicator on the sensor unit
lights up.
Set the sensitivity setting inside the EG-2000 to “L” side, and use the checker.
Check operation of the installed sensor unit.
Use this function only for the daily operation check of the sensor, or during
inspection.
Set the output switch inside the EG-2000 to “H” side, and use the checker.
(1) Turn on the sensor power. Press the check mode switch to
activate “Check mode” for approximately five minutes,
and the alarm indicator blinks. “Check mode” is extended
by approximately five minutes for every detection
operation (alarm indicator lights up). Refer to “8.
Function”
(2) First, press the send button on the glass checker to
activate near the sensor unit. Check that both the alarm
indicator (red) and environmental indicator (orange) light
up.
(3) Activate the glass checker by pointing its transmission
section toward the sensor unit from the glass surface to
be protected, and check the sensitivity. Check it from all
the positions of the glass surface to be protected.
Note: Reliable use of the glass checker is difficult under
the influence of adverse reflection from ceilings,
walls, and/or floors. If this is the case, move the
glass checker position slightly to the left or right,
and check again. If only the environmental indicator
on the sensor unit lights up, the sensitivity is
normal.
Activate the glass checker by pointing its transmission section toward
the sensor unit from the sensor’s operation area, by pressing the send
button.
If the alarm indicator lights up, and a device connected to the alarm
output activates, the alarm operation of the sensor is normal.
If there is a possibility of sound and/or noise in the same space as the glass to be protected, generate actual sound and/or noise as a test, and
check that the environment indicator does not light up. Refer to “8. Function”
If the environmental indicator lights up by sound or noise, change the installation location, or decrease the sensor sensitivity by increasing the
number of the sensor units to be installed and by reducing the detection area per unit.
(5) If detection operation has not been performed for approximately five minutes
after the sensitivity check finishes, the mode automatically switches to
“Operation mode”. Check that the alarm indicator is not blinking before
operation.
