Edwards Signaling 2302 SERIES - Manual

Mounting / Installation
Close the door. Adjust the interlocking bracket into the appropriate
slot in the switch housing to fit the specific curtain door channel.
Place the unit on the channel, making sure the outer lip of the switch
housing is positioned so it overlaps the edge of the channel. See
Figure 1 for proper mounting.

Move the switch and bracket assembly so that it is no more than 48"
from the surface of the floor. This will allow the magnet to roll up with
the door without interference.
Tighten down the mounting bolt enough to hold the unit in place.
For ease of adjustment place a #8 self-tapping screw (provided) in the
appropriate mounting hole to lock switch and bracket housings
together.
Position the magnet so that the word TOP is reading in the same
direction as the Sentrol label on the switch housing, and the center
line of the magnet is aligned with the Sentrol label on the switch
housing. The magnet end should be within 1/4" to 1/2" from the edge
of the switch housing for reliable actuation on heavy steel surfaces.
Make sure the magnet housing is centered within the channel or slat
of the door.
Connect the switch to the multimeter to verify functioning. Push firmly
on the door so that the area the magnet occupies is moved to its
farthest position away from the switch in all directions. If the circuit is
interrupted slide the magnet closer to the switch assembly. Repeat the
above procedures to ensure proper operation. Mark this position on
the door.
Once the correct positioning is established, tighten the mounting bolt
down and then tighten the lock nut against the housing. For extra
mounting strength, drill two .156" dia. holes through the mounting
holes in the housing and fasten with two #8 screws (not provided).
To mount the magnet, drill two 0.156" dia. holes though the mounting
holes in the magnet housing. Fasten down with two #8 self tapping
screws (provided). For faster installation remove the magnet. Clean the
door surface with an alcohol pad. Dry the area off and mount with the
strips of double stick adhesive tape. Mount the tape to the magnet
housing first and then attach the housing to the door, pressing firmly
to ensure proper adhesion.
