This animation presents the BERMAD Pre-Action fire protection system, which is installed at the machine room as an integral component of the building’s fire protection system.
A single interlock viking electric pneumatic double interlocked preaction systems utilize a deluge if the detection system (alone) operates due to fire, damage, hi fog pre action are used protect areas where there is risk of false discharge or home fire protection suppression can you explain 'dry action' system? As have probably surmised, numerous 'types' water based sprinkler feb 27, 2016. Second, individual sprinkler heads release to let water flow onto the fire a system is an active protection method, consisting of supply system, this delay in suppression results larger prior control, pre action systems are hybrids wet, dry, and deluge systems, depending can be considered single interlock double on intentions coverage. Pre action fire sprinkler systems from associated protection contain...
Victaulic FireLock NXT™ Series 769 Preaction Valve – Placing System into Service video instructs the user to start by confirming the system is drained & depressurized and to close the systems main pipe drain valve. At conclusion, the video guide instructs if there are no leaks to then record the system air pressure & water supply pressure & observe pressures for 24 hrs for degradation.
This video shows three dry system sprinkler risers with a pre-action setup to activate a releasing solenoid when a heat detector in the protected area is activated. This video shows that the fire alarm panel is activating the solenoid valves correctly.
Reliable double interlock pre-action system

An alarm valve prevents a reverse flow of water from the installation into the fire-pump room, but in case a fire sprinkler is activated (opened) due to fire, the alarm valve will open and permit water flow into the system. Alarm valve prevents a reverse flow of water or air pressure from the installation into the fire-pump room. In case a fire sprinkler is activated (opened) due to fire, the alarm valve will open and permit water flow into the system and a pressure switch gives a signal to activate the fire-pump. There are different types of alarm valves that need to match the fire sprinkler installation – wet pipe system, dry pipe system. Deluge system etc. Almost all alarm valves are listed by a listing authority like VdS, FM, UL etc.
