The Reserve Manifold Pressure Switch is used for monitoring the supply pressure in the reserve system. The switch is preset @ 1,100 psi [7,585 kPa] decreasing pressure, to alarm before the reserve header contents fall to one day's average supply, indicating reserve
low as per NFPA and CSA. Electrical Characteristics: The electrical rating (continuous inductive) 10 amps 125 or 250 volts AC, 3 amps 480 volts AC.
Automatically reset by snap-action of switch.
Electrical Connection: Normally open/normally closed contacts. Electrical connections are made through a conduit connection to screw terminals on the switch. Pressure connection: NPT.
Adjustment Instructions: Turn adjustment screw clockwise to lower actuation point (switch setting).
The switch enclosure shall be a Nema 4 water tight housing with mounting bracket, 1/4" FNPT bottom inlet gas service line connection and a 1/2" conduit connection on the top.
