RELEASE CIRCUIT TEST MODULE
The release circuit test module, Part No. 423541, is used in place of
the gas motor during test procedures to simulate squib actuation or
gas motor actuation on CHECKFIRE MP-N systems (indicator lamp
on). It is also used when verifying time delay durations. See Figure
13.

SPLICING DEVICE
The In-Line Splice Kit, Part No. 428375, is required for detection
wire connection between the control module and the linear detec-
tion wire or between separate pieces of linear detection cable.
When the splicing device is used in the system, it is recommended
to fill the splice body, Part No. 426783, with a high grade of sili-
cone sealant (Dow Corning 737 or equal) to make a proper seal.
The kit consists of the necessary number of components to
assemble 10 complete assemblies. See Figure 14.

EXTENDER CABLE ASSEMBLY/BATTERY EXTENDER
CABLE ASSEMBLY
The Extender Cable Assembly, Part No. 426601, is used to
conduct functional tests. It, along with the Battery Extender Cable,
Part No. 428042, allows separation of the cover from the enclo-
sure while maintaining circuit integrity. See Figure 15.
