Specication
Use The Unipoint controller provides integrators with a exible and low cost solution to the many applications
requiring ammable, toxic or oxygen gas detection to be incorporated into their control systems. Unipoint
is designed to use industry standard DIN rail allowing it to be easily installed into many different types of
plastic or metal, indoor or outdoor, hazardous or non hazardous area enclosures. It is designed for use
with any mV ammable gas detector as well as any 2 or 3 wire 4-20mA gas detector (subject to overall
power requirements).
User interface
Operation Two pushbuttons for normal operation of resetting alarms and initiating self diagnostic test of system.
Four buttons for user programmable functions via intuitive menu
Backlit display Units of measure, digital gas reading and event code
Other indication Ultra-bright steady/ashing LEDs subject to condition; alarm (red), power (green), fault (amber). In-built
audible alarm 63dB at 0.3 meters.
Termination
Easily accessible plug in screw type terminals. Terminals accept maximum wire diameter 1.5mm
