1.7 GAS CARTRIDGE ACTUATOR (GCA)

The Gas Cartridge Actuator (P/N 70-1651) is an electrically

activated, pressure-producing device used to open the discharge

outlet valve on a Fike container. An electrical charge is sent

through the device upon activation from the control panel: this

overheats the internal bridge wire and ignites the smokeless

powder inside the GCA. The resultant burn-off (approximately 10

milliseconds) generates a pressure wave sufficient to burst the

rupture disc, thus releasing the agent from the container. The

GCA has a stainless steel body with dual thread sizes that enable the device to be installed in any of the

container valve sizes. The GCA has a Mylar seal in the discharge end, and an epoxy plug on the wire end to

create a “sealed” unit with a de-rated shelf life of 10 years. The GCA will not detonate explosives and it is not

considered to be a mass detonating device. Therefore, the GCA has a DOT classification of 1.4, sub-class “S”,

and a shipping number of UN-0323. GCA’s can be transported by any commercial carrier and do not require

special handling permits or licensing.

IMPORTANT NOTE: The GCA is NOT furnished with the standard container assembly and MUST be ordered

separately.

WARNING: Both sets of electrical leads (red-to-blue and yellow-to-green) MUST be shunted together when the

GCA is not installed within the discharge outlet valve, and when testing/troubleshooting the detection

and control system. Failure to do so can result in bodily injury or unwanted system activation.

NOTE: The yellow and green leads are provided for Manual Actuator (P/N 10-2225) connections only. Refer to

the Installation Section of this manual for the wiring diagrams associated with these devices.
