General Air Products’ Vapor Pipe Shield, a UL Listed Vapor Phase Corrosion Inhibitor (VpCI®)...
NFPA 13 requires the supervision of electric actuators (coils on solenoid valves) on preaction or deluge valves. The CoilKeeper™ Solenoid Supervisory Switch (CSS) meets these requirements. Should the coil be removed from the solenoid valve, the CoilKeeper™ initiates a supervisory condition on the releasing panel. Solenoid valve is sold separately.
Q: Why is actuator supervision required?
A: When an actuator is removed from the solenoid valve, this prevents the activation of the fire suppression system putting lives and property at risk.
Q: Why would an actuator be removed?
A: It is common during system testing to remove actuators during the testing process to prevent accidental discharge.
Q: Where is the CoilKeeper™ required?
A: Solenoid supervision is required in all jurisdictions where NFPA 13, 2019 edition or later is enforced. Additionally, it is required in all military and government projects per Unified Facilities Criteria (UFC).
Q: What solenoids can the CoilKeeper™ monitor?
A: The CoilKeeper™ can monitor any solenoid coil from 9-11 Watts (CSS-10) or 22-31 Watts (CSS-25). Refer to datasheet 5401604 for specifications and installation and datasheet 5401607 for the solenoid list.
Q: What fire or releasing panels can the CoilKeeper™ be connected to?
A: The CoilKeeper™ can be connected to all fire or releasing panels. There is no compatibility listing requirement.
Features:
- Solenoid monitoring on preaction/deluge systems
- Ability to show coil state through simple LEDs
- Detects open and shorted coils
- Can be mounted at the solenoid or remotely
- Provides visual indication of coil and the releasing circuit status
