to Figure 14.
•
If DIP Switch 4 is ON, the OR condition is
selected. The upper or lower beam pairs must
be broken to cause an alarm.
•

3. Choose whether or not to bypass alarms by setting
DIP Switch 5 to ON or OFF when the EDC
activates. Refer to Section 1.3.7 Environmental
Discrimination Circuit (EDC) on page 4 for more
information.
The EDC is always on. DIP Switch 5 (BYPASS)
controls the alarm condition relative to the EDC
relay status. Refer to Figure 4 on page 4.
•
If DIP Switch 5 is ON, the system alarms only
if the EDC relay is not activated. If the EDC is
activated, the system does not indicate an
alarm.
•
If DIP Switch 5 is OFF, the system alarms
regardless of whether the EDC relay is
activated or not.
Connect the EDC to a trouble circuit, and
check the system any time the EDC relay
activates.
If the EDC remains activated for prolonged
periods when the beam path is clear, the
beam might be misaligned. Refer to
Section 4.2 Alignment on page 13 to re-
align the beam.
4. Use a Phillips head screwdriver to adjust the rotary
INTERRUPTION TIME switch according to how
sensitive you want the detector to be to movement
(catch performance). Refer to Figure 14 for the
location of the INTERRUPTION TIME switch.
Refer to Table 4 for interruption times and
corresponding catch performance examples.
For UL applications, the interrupt time
cannot be set above 75 ms.
For best performance when using the AND
mode, do not exceed 100 ms beam
interruption time.
