Electrical Monitoring of Isolation Valves in a Residential Sprinkler System is a requirement of BS9251:2021

The aim of monitoring sprinkler systems is the continuous supervision of the main functions of the system, i.e. those whose failure might impair the correct automatic operation of the system in case of fire, and the raising of a supervisory alarm to allow corrective measures to be taken.

Sprinkler Monitoring

BS 9251:2021; Table 5, sets out the required items to be monitored, these are:

  • Pump – Automatic test cycle failure.

  • Pump – Power failure.

  • Pump running.

  • Tank – low water level alarm.

  • Zone stop valve not fully open.

  • All other dedicated sprinkler stop valves.

  • Trace heating system fault.

  • Supervised circuits fault.

In addition to the items described in Table 5, it is important that all flow switches are also monitored. It may be the case that these form part of the Fire Detection System, so are monitored for activation on that system.


If the building does not have a dedicated fire alarm system for the communal areas, it’s important for the flow switches to be monitored by another system. FloWatch 9251 is perfectly suited for this application.
