Specification
The Colt C300, C300N Double Check Detector Assemblies
shall consist of two independent Tri-Link Check modules within
a single housing, sleeve access port, four test cocks, and two
drip tight shutoff valves. Tri-Link Check shall be removable and
serviceable, without the use of special tools. The housing shall be
constructed of 304 (Schedule 40) stainless steel pipe with groove
end connections. Tri-Link Checks shall have reversible elastomer
discs and in operation shall produce drip tight closure against the
reverse flow of liquid caused by backpressure or backsiphonage.
The bypass assembly shall consist of a meter, which registers
in either gallon or cubic measurement, a double check valve
assembly, and required test cocks.
The integrated supervisory tamper switch on the OSY model
shall have continuity with the valve fully open and activate within
two (2) turns from open. The device consists of two SPDT
switches and is designed to send a tamper signal when the valve
is closed and when the switch is removed from the valve. In
the neutral position, the switch indicates the valve is fully open.
Closing the valve causes the switch rod to come out of the valve
stem groove, activating the switch. Removing the tamper switch
also activates the switch. Assembly shall be a Colt C300, C300N
as manufactured by Ames Fire & Waterworks.
