Sprinkler Stop Valve Inside - Safety Signs by Caledonia Signs

A critical fire safety sign used to indicate the exact location of a building’s sprinkler system stop valve inside a room or enclosure. This valve allows trained personnel or firefighters to shut off the water supply to the sprinkler system during maintenance, system testing, or accidental activation, while ensuring that the system can be quickly reactivated in an emergency. Clear signage prevents delays, confusion, or misuse during critical situations.

Using this sign helps ensure compliance with fire safety regulations and standards, such as BS EN 12845 (Automatic Sprinkler Systems – Design, Installation, and Maintenance). Proper identification reduces the risk of accidental tampering, unauthorised operation, or delays in locating the valve during emergencies. It also supports regular inspection and maintenance routines, ensuring the sprinkler system remains fully operational and reliable.

Placement of the sign is essential for visibility and effectiveness. It should be installed directly on the door of the room or enclosure housing the sprinkler stop valve, or immediately above the valve itself, at eye level, and in a location free from obstructions. In large or complex buildings, additional directional signs may be used to guide personnel from main access points to the valve. For enhanced visibility in low-light or emergency conditions, photoluminescent or reflective signage is recommended.

Additionally, displaying a Sprinkler Stop Valve Inside sign promotes a culture of fire safety and preparedness. It ensures personnel can quickly locate and operate the valve when required, supports compliance with maintenance procedures, and reinforces the organisation’s commitment to protecting lives and property through proper management of fire protection systems.
