Use

The Zareba Unipoint controller provides   integrators with a flexible and low cost solution to the

many applications requiring flammable,   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 flammable 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/flashing 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 1.5mm2 (16 AWG)
