Guardian Plus by Sensors for Safety Ltd is a premium low cost gas detection system designed for use with sensors in Zone 1 and Zone 2 classified areas along with all other Industrial and Commercial premises.



Guardian Lite is a low cost addressable gas detection system primarily used by Fire Alarm Companies and BMS Installers as a 24VDC system which can integrate in to their control systems. Due to its popularity, a standalone 24VDC/230VAC system for up to 4 sensors has been added - this system can be expanded up to 64 sensors with an additional power supply. Due to its low cost, the Guardian Lite panel is also used as a door entry alarm in place of sounders and beacons - all working from the same addressable cable network.



Typical installations of the Guardian Lite are as follows:
Boiler Rooms with sensors for Flammable Gas (Natural Gas CH4 and LPG) and Carbon Monoxide CO
Swimming Pool Plant Rooms with sensors for Chlorine CL2 Chlorine Dioxide CLO2 and Carbon Dioxide CO2
Car Parks with sensors for Carbon Monoxide CO for petrol engine exhaust fumes, Nitrogen Dioxide NO2 for diesel engine exhaust fumes and LPG sensors for fuel spills from LPG vehicles
Ambulance Stations with sensors for Carbon Monoxide CO for petrol engine exhaust fumes and Nitrogen Dioxide NO2 for diesel engine exhaust fumes


Guardian 1 is a fully featured single channel gas detection control system. The Guardian 1 comes in 24VDC or 230VAC versions and can be used with a remote sensor or built in depending on the application. Guardian 1 can be used with any 4-20mA sensor or 3 wire catalytic bridge type sensor.
The Guardian 1 can also be connected to a Guardian Plus network to form part of a larger network. 




Typical installations of the Guardian Lite are as follows:
Small Boiler Rooms with a sensor for Flammable Gas (Natural Gas CH4 and LPG)
Gas Meter Rooms with a sensor for Flammable Gas (Natural Gas CH4 and LPG)
Pub/Hotel Cellars with a sensor for Carbon Dioxide CO2
Universities with a sensor for which ever gas is being used on a small project


Guardian 1 can also be used as a single line sample system with sample lines of 50 metres or 100 metres.



Typical installations of the Guardian Lite sample system are as follows:
Warehousing sensors for VOC's (PID), flammable liquid storage, chemical storage
High Level flammable gas sensing in difficult to reach locations


Guardian 4 is a fully featured four channel gas detection control panel which can be used for our full range of flammable, toxic and asphixiant 4-20mA and catalytic bridge gas sensors. By way of plug in modules the system can be configured 1 - 4 channels with a mixture of gas types. Each channel has independent alarms and repeated 4-20mA outputs along with system global alarms. This system has always been popular in the water and waste water industries along with commercial boiler houses and many other applications

Typical installations for the Guardian 4 are as follows:
Water works sensors for Chlorine CL2 Sulphur Dioxide SO2 Ozone O3 Hydrogen H2
Waste Water works sensors for Methane CH4 Hydrogen Sulphide H2S Oxygen O2 Carbon Monoxide CO Carbon Dioxide CO2 Ammonia NH3 Chlorine CL2
Commercial boiler houses sensors for Methane / Natural Gas CH4 LPG Carbon Monoxide 

Guardian Plus is the most versatile system within the Guardian range. The system can come in a wall mounting enclosure, DIN rail mount or 19" versions.
Within the Guardian Plus range there is a choice of the following:
Guardian Plus Direct: 1 - 16 channels 4-20mA sensors (8 of these channels can be configured by the way of an additional input card for direct access from catalyic flammable gas sesnors
Guardian Plus Addressable: 1-64 canbus addressable gas sensors

Guardian Plus +: Combination of 1 - 16 channels 4-20mA sensors (8 of these channels can be configured by the way of an additional input card for direct access from catalyic flammable gas sensors AND 1 - 64 canbus addressable gas sensors

This system can be further extended to over 1000 channels by way of a Guardian Plus network controller. The system also comes with dual RS485 comms and can be supplied with a 'Guardian Plus Soft' datalogging and system control software package
