- Dry Pilot Actuation
- Opening of a dry pilot sprinkler, releases pneumatic pressure from the pilot line. In turn, the Dry Pilot Actuator opens and releases water from the Diaphragm Chamber faster than it can be replenished through the 1/8 inch (3,2 mm) restriction provided by the Model ASV-1 Automatic Shut-Off Valve in the diaphragm supply connections.
- This results in a rapid pressure drop in the Diaphragm Chamber and the force differential applied through the Diaphragm that holds it in the set position is reduced below the valve trip point.
The water supply pressure then forces the Diaphragm open permitting water to flow into the system piping, as well as through the Alarm Port to actuate the system alarms.

+ What is Proposition 65?
The purpose of Proposition 65 is to ensure the public is informed about the potential exposure to chemicals known to cause cancer,
birth defects, or other reproductive harm.
The law requires the State of California to publish a list of these chemicals.
This list currently contains ~1,000 chemicals; chemicals are added and removed regularly.
Johnson Controls products may have traces of various chemicals that are on the list,
however they are all a part of the normal manufacturing, distribution or labeling process.
