6 USER GUIDE
The GRM2 CO2 series monitor is operated via a door mounted user interface. This includes a traffic
light alarm display, an LCD panel and a 5 button keypad.
On power up of the monitor, self-diagnostics are carried out. This will cause the traffic lights to flash
and some messages may appear on the screen. If the monitor is starting from cold, it is suggested
that it is left to warm up for 24 hours to ensure correct readings. Following power up, you are
presented with the home screen where the current status of the monitor is shown.
The
monitor’s features can be accessed or viewed via the keypad functions as described below.
Local and remote access to this information is also available via the network module RJ45 Ethernet
connector. Please contact Parasense for more information (see back page of this manual for contact
details).
If there is no keypad activity for 3 minutes the LCD back-light will switch off and the display will go
dark. The traffic light display will still function to the present status of the system. Any keypad activity
will cause the LCD back-light to switch on.
To adjust the LCD contrast, simultaneously press and hold the & buttons. This will activate the
contrast function. Using the & buttons, you may now adjust the contrast of the LCD to the
desired level.
Once complete press the centre button to close the contrast menu. If the screen is completely
blue, press the button until text is visible. If the screen is white, press the button.
KEYPAD FUNCTIONS
To navigate through menus on the monitor, there are four directional arrow buttons. Use the
buttons to move the cursor up and down to the required option. Pressing the action button of the
keypad, whilst the cursor is on the required option, will action the request. The buttons will move
the cursor to the left and the right where applicable, but can also be used to view the previous and
next page of data where available.
