responsibility if the fire suppression system is not connected,
installed, or maintained properly.
Installation Requirements
The fire suppression system must be supplied with a minimum
water pipe size of 1/2” and be provided with 40 psi +/- 20 psi
(2.75 bar +/- 1.37 bar) of pressure. For use of optional manual
bypass, a second source with the same piping and pressure
requirements is required.
Flexible 1/2 feeds must be provided to avoid damage to
electric water solenoid valve by vibration.
Important
Flexible supply line/coupling must be used.
Solenoid valve failure due to hard plumbing
connections will void warranty.
