Securing the Detection Wire

After the linear detection wire has been loosely in-
stalled, secure it to the equipment being protected as
follows:
1. Begin at the control module with the first section
of detection wire. If this section is sufficient to
cover the total hazard area, no additional lengths
are required. If additional lengths are required,
remove blank plugged connector from the end of
first length and add lengths until the total hazard
area(s) is covered.
NOTE: Remember to leave closed blank plug connec-
tion on the last length of detection wire.
When making connection, push plug into recep-
tacle until a "click" is heard (Figure 2.3-8). Plugs
and receptacles are keyed to allow insertion only
in one direction. After "click" is noted, apply a
small amount of back pull to confirm connection
has been made.

2. Secure the wire every 12-18 in. (30-45 cm) through-
out the hazard area(s) using the black nylon cable
ties provided. Secure more often if desired, or to
keep the wire out of the way. Secure the wire to
mounting surfaces, decks, struts, hydraulic hoses
in the area, or any secure, non-moving part of the
protected equipment. Always keep the previously
mentioned guidelines in mind when installing the
wire.
Preliminary Test Before Final Hook-Up
All necesssary linear detection and power wire instal-
lation is now completed . Before arming the actuator
with the squib, it is necessary to check to insure all
connections are made properly.

1. The Power Wire

a. Depress the button on top of the control module
and note green indicator light (Figure 2.3-9).
With button, depressed, light should be on. This
indicates the power wire is installed correctly to
the control module. If light does not appear,
check all connections to insure they are
snapped together. Retest by depressing but-
ton. If light is not "On" refer to "Troubleshooting
Section" covered in this section.
b. If battery power is correct, proceed to checking
total system power.
