2. BUZZER ALARM
OPERATION - RE-CAL MODE
The Re-Cal mode function is enabled by default, it must be disabled via the menu if it is not required.
The Re-Cal function will monitor the device and indicate when the CO sensor should be re-calibrated.
If the device determines that the sensor requires re-calibration it will enter Re-Cal mode. This will cause
the Status LED to blink red and the buzzer to beep once every 10 minutes. The LCD will periodically show
"ReCal Required". If enabled, and the device is in Re-Cal mode, pressing the TEST switch will "silence" the
buzzer due to the ReCal alarm only. Buzzer silence due to the ReCal alarm will hold until the ReCal condition
is reset via the menu. The buzzer may still activate due to a CO setpoint alarm if enabled.
OPERATION - USER MENU
The device has several parameters that can be configured locally via the User menu using the keypad and
LCD. All parameters default to typical values but the installer may want to change some values. In some
cases, such as the device network address, the installer MUST change the settings before operation. Any
changes made are saved in non-volatile memory and are restored in case of a power loss. Only the menu
items relevant to the device model will be shown. The menu can be accessed at any time after the warm-
up mode and if there is 5 minutes of inactivity the menu will close and normal operation will continue.
Note that the TEST switch has no affect when the User menu is in use.
The menu has several items as shown below. To enter the menu, press and release the <MENU> key. This
will enter the User menu step 1, pressing the <MENU> key a second time advances to step 2. Each press
of the <MENU> key advances the menu item. No values are saved or changed by using the <MENU> key.
The <ROLL> key is used to make changes to program variables by scrolling through the available options.
Holding the <ROLL> key pressed will scroll through some options at a faster rate. When a value is changed,
use the <SAVE> key to save it to memory and advance to the next menu item. The default values are
shown in each step below.
