S4S Guardian®​-Plus


Sensors for Safety Ltd can supply chlorine gas leak equipment  for use in Swimming Pool Plant Rooms. Our low cost S4S Guardian®-1  system can be used for small  Plant Rooms, whereas larger areas will require our S4S Guardian®-​Lite  system which is capable of monitoring up to 16 detection points.

For even larger more complex systems with RS485 and 4-20mA outputs our premium S4S Guardian®-Plus  system covers all eventualities. 


Case Study:

We were recently called to Repton Sports Centre in Derbyshire to quote for a replacement gas detection system - to replace an obsolete system that the manufacturer was wanting over £1000.00 just to turn up and look at!

We supplied, installed and commissioned one of our S4S Guardian®-1  control systems complete with our S4S Guardian® -Point SA Chlorine (CL2) gas sensor.

Two weeks after being installed there was a major incident where Chlorine gas was released causing several people to be treated for the effects of Chlorine (as reported in the local press).

If you would like a quote for a service of your existing system or to supply install and commission a new system please contact us for a no obligation quotation.

As an experienced gas detection maintenance service provider, Sensors for Safety Ltd provides a streamlined management structure and delivers increased efficiency and value for money.
