Securing the Detection Wire
After the linear detection wire has been loosely
installed, secure it to the equipment being protected
as follows:
1. Begin at the control module with the first sec-
tion 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
connection on the last length of detection wire.
When making connection, push plug into receptacle
until a "click" is heard (Figure 2-11). Plugs and recep-
tacles are keyed to allow insertion only in one direc-
tion. 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)
throughout 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 equip-
ment. Always keep the previously mentioned
guidelines in mind when installing the wire.
Preliminary Test Before Final Hook-Up
All necessary 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
2-12). With button, depressed, light should
M02005
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 button. If light is not on, refer
to Troubleshooting The Electric Detection
System covered in this section.
b. If battery power is correct, proceed to check-
ing total system power.
