BS92151: 2021 Sprinkler systems for residential and domestic occupancies code of practice

This British standard gives recommendations for the design, installation, components, water supplies and backflow protection, commissioning, maintenance and testing of fire sprinkler systems installed for life safety purposes with additional benefits for property protection.

This British standard also gives recommendations for sprinkler protection of domestic and residential premises where the building height is either more than four storeys or 18 m and above, whichever is the lower. The recommendations of this British standard are also applicable to any addition, extension, repair or other modification to a residential sprinkler system.


Why do I need to monitor the fire sprinkler system?


Section 5.15 of BS9251:2021 states:

"Except for category 1 systems, all valves which control the flow of water to the system should be electrically monitored for the open position."

Section of BS9251:2021 states:

"An alarm to indicate low water levels should be provided for a stored water supply"

Section 5.18 of BS9251:2021 states:

"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.

All devices used for monitoring should have at least IP 54 protection as specified in BS EN 60529 and be connected to a common supervisory alarm device.

With the exception of category 1 systems, all devices that provide a fault signal or an alarm device signal, should be via supervised circuits”

Why FloWatch


FloWatch are specialist manufacturer of fire sprinkler monitoring system. FloWatch monitoring system monitors the following elements of the system:

  • Flow switches for activation of the sprinkler system. FloWatch is fully addressable so each flow switch can be easily identified. This can also be interfaced with an automatic fire alarm and detection system if required under the fire strategy of the building

  • Monitored isolation valves not being in the correct position

  • Low level tank switches for low water content in a storage tank


  • Booster set for activation (pump running) or faults of the pump


  • Trace heating signals 

FloWatch outputs provide the facility to:

  • Send a signal to an alarm system upon activation of any flow switch

  • Send a signal to BMS if any fault or alarm occurs within the sprinkler system

  • Correctly activate the priority demand valve in accordance with BS9251:2021 (when used in conjunction with Rapidrop PDV

FloWatch operates in two formats;
Offline Mode
  • Display/identify the relevant system faults/alarms and the associated input device name/location on the LCD
  • The relevant LED will illuminate in the event of any fault (amber LED) or alarm (Activation of device - red LED)
  • Sound in the event of any fault or alarm activation
Online Remote Service (Subscription required) In addition to the offline operation, the online remote service enables the user to:
  • Remotely view the system state and setup via web browser
  • Receive email alerts of any faults and alarm activations
  • Receive text message alerts of any faults and alarm activations
Note: FloWatch provide 12 Months Free subscription with all systems.

  • Can I connect flow switches to the FloWatch monitoring dystem?
    Yes. The FloWatch system can monitor up to 132 configured inputs. The type of input can be varied easily on the programming software via a drop down menu with image of the device. Each input is fully addressable so can be given a name and location which will be displayed on the master panel in the event of an activation or fault. When a flow switch is activated the "Alarm" LED on the front of the master panel will turn red, an audible alarm will be raised at the master panel and relevant name will be displayed on the LCD screen.
  • Can FloWatch provide wiring diagrams for my system?
    FloWatch will provide a free system schematic with your first order. We would require a schematic of the particular system.
  • How many isolation valves /flow switches can be monitored?
    Up to 4 devices (inputs) either flow switches or monitored isolation valves (or combination of both) can be monitored on the master panel as a stand alone unit. Expansion modules can be added to the master panel to increase the number of inputs. Expansion modules are available in 4 Way (4 Inputs) and 8 Way (8 Inputs) A total of 16 expansion modules can be connected to a single master panel, meaning up to 132 devices (inputs) can be monitored from a single master panel.
  • What power supply is required?
    230VAC single phase supply to the master panel. Expansion modules do not require separate power supplies as these take their power over the network wiring from the master panel.
  • Does the FloWatch expansion module require a power supply?
    No - It is powered via the MODbus network cabling (It is powered by the master panel radial circuit wiring)
  • Can I install this on a commercial sprinkler system?
    FloWatch has not been designed to be used in a commercial sprinkler system in accordance with EN10285. It has been designed to be used for systems installed to BS9251.
