Pressure Trip

Description

The pressure trip is connected to the actuation or discharge
line of an AQUASONIC system. By either pneumatic or
manual actuation, the pressure trip can release spring or
weight powered devices to close doors and windows, open
fuel dump valves, close fire dampers or close fuel supply
valves. The pressure trip is constructed of brass with two
1/4 in. NPT fittings for connection to discharge or actuation
lines. The link on the pressure switch is released either
pneumatically, by agent discharge pressure; or manually, by
use of the pull ring. The link then releases the device which
performs the auxiliary functions.

Note:

Operating pressure must be a minimum of 75 psi
(5.2 bar) with a maximum load of 70 lb (31.8 kg).
