2. If wall mounting is desired, be sure the box screws are oriented to upper right and
lower left corners, FIGURE F. The volume of the box is determined by the number of
conductors entering and exiting the box. Use 1-3/4 cubic inches per conductor (#16
AWG).

INSTALL MOUNTING PLATE & CONNECT WIRES
1. Remove the plug and wire assembly from the shipping container and wire it in
junction box as follows:
2. Major Circuits (power in, power out, and alarm contacts) have two wires, one for the
incoming circuit and one for the outgoing circuit. Auxiliary relay contacts are single
wire circuits. Make connections as detailed on wiring diagrams, FIGURE G.
3. Lace the connector through the provided mounting plate and secure the plate to the
junction box.
NOTICE: FOR TROUBLE AREAS WHERE THERE CAN BE A LARGE VOLUME OF
AIR BLOWING OUT THROUGH THE ELECTRICAL JUNCTION BOX. YOU MUST
FIRST INSERT THE CARDBOARD SHIELD PACKAGED WITH YOUR SMOKE
DETECTOR TO THE BACKSIDE OF THE SMOKE DETECTOR BEFORE SECURING
IT TO MOUNTING PLATE.

SECURE SMOKE DETECTOR TO MOUNTING PLATE
1. Plug the wire connector into the detector base.
2. Place the smoke detector up to the mounting plate, rotating it clockwise until smoke
detector firmly snap locks into place. Keep the smoke detector parallel to the
mounting plate so upper and lower tabs on plate seat correctly into detector,

CHECKOUT & TROUBLESHOOTING
1. Turn test knob on each unit to the NORMAL position and supply power to the system
Control Unit.
a. If the fire alarm sounds, one or more smoke detector connections to the fire
detection circuit may be reversed. Check wire color codes and trace.
b. If the trouble buzzer sounds, the fire detection circuit may be reversed or
disconnected at the Control Unit.
2. Testing with the Test Knob.
a. Rotate the test knob on the front of the unit to TEST 1 position (counter-
clockwise). See FIGURE I. The alarm should sound in less than 20 seconds.
b. To reset the system, return the knob to its NORMAL position and use the reset
switch on the system Control Panel. Hold in reset for 5 or more seconds.
c. To test smoke detector for high sensitivity, rotate test knob clockwise to the TEST
2 position. Alarm should remain silent. Return test knob to normal position. If
your smoke detector alarmed during TEST 2, the smoke detector's sensitivity has
become too high and may cause false alarms. This may mean your smoke
detector is dirty and should be cleaned as described in the below maintenance
procedure.
d. If your detector still alarms in TEST 2 position following washing and
recommended drying time, return it to Gentex Corporation for service. The test
knob actually tests the sensitivity of the unit by using the same principle involved
as when smoke enters the smoke detector. When you turn the test knob to the
TEST 1 position, you are scattering the detector's LED light to the equivalent of
3.4% actual smoke. TEST 2 position is equivalent to 0.85%.
