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 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 Guardian Point 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.

We are able to offer Maintenance contracts on all types and makes of gas detection including (but not limited to)  Crowcon Detection Instruments, Drager,  GDS Technologies, GMI, Honeywell, IGD, MSA, Seitron, Sensitron, Oldham & Zellweger.

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.
