Peak the voltage to ensure a stable and
trouble-free detector.
5. After completing the fine-tune alignment, remove
the test cable.
6. Replace and secure the receiver's cover.
7. Check the status of the receiver's green LED to
ensure it is still flashing.
8. With the meter still connected to the test cable,
reinstall this cable to P6. Route the test cable
through the opening in the cover (white lead towards
center of the receiver).
9. At this point, you can perform an Alarm Test.
Connect the D1005's white and black wires. Reset
the receiver by temporarily removing power.
10. Press the receiver's Setup button, located below the
P6 and test cable connection (refer to Figure 15).

1 - LEDs
Only press the Setup button if the covers
are on both the transmitter and receiver.
A 1-min to 2-min automatic internal setup process
begins. This setup ends in a reference voltage that is
used to measure beam blockages.
The red and yellow LEDs turn off and the green
LED turns steadily on. After some voltage
fluctuations, the meter sets to 5.0 VDC.
During this time, do not block the beam or
move the units.
11. At the end of the setup, the receiver's green LED
flashes and the voltage decreases to a range from
3.8 VDC to 4.2 VDC. Use this voltage as a
reference when you compare later readings to
determine the need for cleaning. If the voltage is not
within this range, press the Setup button.
12. After setup, remove the test cable.
13. Reconnect the D306 connector if used.
14. Replace and secure the access door.

Fire Alarm Reset

1. Reset the receiver after a fire alarm by removing
power from the receiver for at least 1 sec.
2. Reapply power (refer to Section 7.4 Power Outage).
7.2 Cleaning
1. Clean the outside of the covers a minimum of once
each year. Use a common window cleaner and a soft,
clean cloth. Under normal conditions, there is no
Trouble alarm if the beam is not continuously
blocked longer than 18 sec.
2. Recheck the reference voltage. If voltage is less than
3.8 VDC or greater than 4.2 VDC, calibrate the
receivers (refer to Section 7.3 Reference Voltage
Calibration).
Clean covers are necessary for proper
reference voltage readings.
7.3 Reference Voltage Calibration
1. Check the detector's reference voltage a minimum
of once each year. Check the voltage more often if
required by local regulations or AHJs.
2. Remove the receiver access door and measure the
reference voltage using the supplied test cable. You
can also measure the voltage at the D307 (if used).
3. If the voltage is less than 3.8 VDC, remove the
cover and use the Setup switch to perform a
fine-tune alignment.
If the voltage is greater than 4.2 VDC, press the
Setup button. You do not need to calibrate if the
voltage is between 3.8 VDC and 4.2 VDC.
7.4

Power Outage

When power is removed and reapplied to the receiver,
such as in a power outage or alarm reset, the original
reference voltage information is lost.
If the cover is on during powerup, the receiver
automatically restarts the internal setup process for a
new reference voltage when power is applied. If the
cover is off, reattach it and press the Setup button.
