OPERATION

System comprises mainly of two configurations:

1. Double Interlock

Double Interlock configuration is more commonly used in industry and it comes with two options:

  • 1. Electric/Pneumatic
  • 2. Electric/Electric

Both these options have been specified in individual datasheets.

2. Single Interlock

Single Interlock configuration comes in three options:

  • 1. Wet Pilot
  • 2. Dry Pilot
  • 3. Electric

Double Interlock Pre-Action System with Electric/Pneumatic Actuation:

This is most commonly used system. This system utilizes a Deluge Valve Model ES0201 and Riser Check Valve Model CH. The Riser Check Valve isolates the Deluge Valve from the system air pressure. Riser Check Valve provides an air check, so that the system can be automatically pressurized with a supervisory air or nitrogen pressure of 42 psi (2.94 bar). A supervisory low pressure alarm switch can be set at 20 psi (1.40 bar), on decreasing pressure, to indicate whether there are any abnormal leaks in the sprinkler system piping. Loss of air pressure from the system due to accidental leakage will not cause Deluge Valve to open.

The releasing trim for Deluge Valve utilizes a Solenoid Valve and a Dry Pilot Actuator in a series configuration. The system air pressure holds the Dry Pilot Actuator closed, whereas the Solenoid Valve remains closed until it is electrically energized by a Deluge Valve Releasing Panel (automatic control unit). The Releasing Panel is operated by either a fire detection device or manual electric pull station. In order for the Double Interlock Pre-Action System to automatically actuate, two independent events must occur. The Deluge Valve Releasing Panel must operate and open the Solenoid Valve upon automatic operation of the electric fire detection initiating circuit and the sprinkler system piping must lose air pressure due to operation of one or more sprinklers. The Double Interlock Pre-Action System will automatically actuate only when both the Dry Pilot Actuator and the Solenoid Valve are open at the same time. Unintended opening of just the Dry Pilot Actuator or the Solenoid Valve will only cause an alarm and not actuate the system or flood the sprinkler system piping.

Double Interlock Pre-Action System with Electric/Pneumatic Actuation:

This system utilizes a Deluge Valve Model ES0201 and Riser Check Valve Model CH. The Riser Check Valve isolates the Deluge Valve from the system air pressure. Riser Check Valve provides an air check so that the system can be automatically pressurized with a supervisory air or nitrogen pressure of 18 psi (1.26 bar). A supervisory low pressure alarm switch can be set at 6 psi (0.42 bar), on decreasing pressure, to indicate whether there are any abnormal leaks in the sprinkler system piping. Loss of air pressure from the system due to accidental leakage will not cause Deluge Valve to open.
The releasing trim for the Deluge Valve utilizes a Solenoid Valve that is energized with cross-zone releasing circuit of release panel.
The Solenoid Valve remains closed until it is electrically energized by a Deluge Valve Releasing Panel (automatic control unit). The Releasing Panel is operated by either a fire detection device or manual electric pull station. In order for the Double Interlock Preaction System to automatically actuate, two independent events must occur. Zone 1 of the Releasing Panel must operate upon automatic operation of the electric fire detection initiating circuit or operation of the electric-manual pull initiating circuit, and Zone 2 of the Releasing Panel must operate via the Low Air Pressure Alarm Switch upon loss of air pressure from the sprinkler system piping, due to operation of one or more sprinklers. The Double Interlock Preaction System will automatically actuate only when both Zone 1 and Zone 2 of the Releasing Panel have operated, energizing the Solenoid Valve.

Single Interlock Pre-Action System with Wet Pilot Actuation

This system utilizes a Deluge Valve Model ES0201 and Riser Check Valve Model CH. The Riser Check Valve isolates the Deluge Valve from the system air pressure. Riser Check Valve provides an air check so that the system can be automatically pressurized with a supervisory air or nitrogen pressure of 18 psi (1.26 bar). A supervisory low pressure alarm switch can be set at 6 psi (0.42 bar), on decreasing pressure, to indicate whether there are any abnormal leaks in the sprinkler system piping. Loss of air pressure from the system due to accidental leakage will not cause Deluge Valve to open.
System actuation is carried out by Wet Pilot Line, consisting of Wet Pilot Sprinklers for detection. Actuation of Wet Pilot Line releases Deluge Valve, which allows water to flow into sprinkler line.

Single Interlock Pre-Action System with Dry Pilot Actuation

This system utilizes a Deluge Valve Model ES0201 and Riser Check Valve Model CH. The Riser Check Valve isolates the Deluge Valve from the system air pressure. Riser Check Valve provides an air check so that the system can be automatically pressurized with a supervisory air or nitrogen pressure of 18 psi (1.26 bar). A supervisory low pressure alarm switch can be set at 6 psi (0.42 bar), on decreasing pressure, to indicate whether there are any abnormal leaks in the sprinkler system piping. Loss of air pressure from the system due to accidental leakage will not cause Deluge Valve to open.
System actuation is carried out by Dry Pilot Actuator, consisting of Dry Pilot Sprinklers for detection. Actuation of Dry Pilot Actuator releases Deluge Valve, which allows water to flow into sprinkler line. The Dry Pilot Sprinkler line to be pressurized with 42 psi (2.94 bar) air pressure.
Two independent Pressure Maintenance Devices are to be utilized for maintaining the supervisory air pressure and Dry Pilot line pressure.

Single Interlock Pre-Action System with Electric Actuation

This system utilizes a Deluge Valve Model ES0201 and Riser Check Valve Model CH. The Riser Check Valve isolates the Deluge Valve from the system air pressure. Riser Check Valve provides an air check so that the system can be automatically pressurized with a supervisory air or nitrogen pressure of 18 psi (1.26 bar). A supervisory low pressure alarm switch can be set at 6 psi (0.42 bar), on decreasing pressure, to indicate whether there are any abnormal leaks in the sprinkler system piping. Loss of air pressure from the system due to accidental leakage will not cause Deluge Valve to open.
System actuation is carried out by supplemental detection system, which typically comprises of 24 VDC heat detectors, smoke detectors, manual pull stations, etc. Actuation of the detection system automatically operates the Deluge Valve, allowing water to flow into the sprinkler piping system, to be discharged from any sprinklers that are open.

INSTALLATION REQUIREMENT

The Pre-Pack Cabinet and all interconnecting piping must be located indoors in a readily visible and accessible location and in an area having minimum temperature of 4oC (40oF). Heat tracing is not permitted. The automatic sprinklers, releasing devices, fire detection devices, must be UL Listed.
