Navigating the Menu 

Normal Operating Mode 

 

After system power-up, the normal 

operating screen will be displayed. It 

provides at-a-glance system status, 

showing real-time gas concentrations. In 

this example, Channel 1 gas concentration 

has exceeded the warn and alarm 

setpoints. Channel 2 indicates a fault due 

to faulty wiring or a sensor signal less 

than 1 mA. The Warn, Alarm and Fault 

indications will flash until the conditions 

are cleared. PREV or NEXT to go to Channel 

View screens MENU to go to main menu 

screen.

Channel View 

 

Channel view displays only the status of 

the channel being viewed. It also displays 

the room/zone location. Warn, Alarm 

and Fault indications will flash until the 

conditions are cleared. PREV or NEXT to 

view normal operating screen or next 

channel view screen. MENU to go to main 

menu screen. 

An over-range condition is indicated by 

flashing of the full-scale reading. This also 

indicates that the sensor output is over 20 

mA. 

Main Menu 

The main menu can be accessed by 

pressing the menu key at any time. Use 

the alpha-numeric keys to select a sub-

menu, or NEXT to advance to the next 

menu screen. ESC to return to the normal 

operating screen. 

Main Menu (cont.) 

Alarm Log 

The alarm log captures every event 

in chronological order, with the most 

recent event displayed first. 10,000 

events can be stored, with the oldest 

events being automatically truncated, 

once the alarm log is full. Time/date 

stamp and event number are also 

displayed. PREV or NEXT to scroll. 

Hold button in for turbo-scroll. ESC 

to return to normal operating screen. 

MENU to return to main menu screen. 

Cal Mode 

Calibration mode allows for sensor 

calibration and maintenance by 

holding the relays in their normal 

state, preventing unwanted alarms. If 

the unit is left in Cal Mode, it will stay 

active for 48 hours and then return 

to normal operating mode. Make 

sure the concentration values have 

dropped below the warning and alarm 

setpoints before exiting. ESC to exit 

from Calibration mode and return to 

normal operating mode. The analog 

outputs are not affected by calibration 

mode and are allowed to increase to 

full scale.
