Abstract
A device and method for locking out an explosion suppressor that includes a discharge valve with a load end and a discharge end. The load end and the discharge end define a discharge path therethrough. The discharge valve includes a side opening transverse of the discharge path. A storage container is connected to the discharge valve at the load end. The storage container delivers a pressurized fluid to the discharge valve through the load end when the system is in a discharge mode. A lockout member is removably insertable into the side opening. The lockout member mechanically blocks the discharge path, whereby the lockout member prevents inadvertent fluid discharge through the discharge end of the discharge path. The presence of the lockout member is monitored by a magnetic switch.
