GETTING STARTED DISPLAY ICONS

GENERAL: BW DEFENDER icons and intelligent alpha-numeric display provide clear

“Status at a Glance” advice at all times. Only applicable icons will be displayed at any

one time.

What the Various Icons Mean:

1) Alarm Icons: One or more of these icons will light up during an alarm condition:

HIGH indicates high alarm; LOW indicates low alarm. Both HIGH and LOW are lit

up during a Multiple Gas sensor alarm.

2) Gas Bar Icons: Identify the gas measured and the units of measure (ppm, %, and

%LEL). Gases not being measured are not displayed.

3) Calibration Icons: Shown only when the unit is performing calibration operations.

4) Key Icon: Appears when calibration and alarm setpoint adjustment is password

protected, or locked out. Also appears if the password is required from the user.

5) Up and Down Arrows: Appear when the unit is waiting for user input. This occurs

during password entry and alarm setpoint entry.

6) Fan Icon: Indicates condition of the motorized sampling pump (if one is installed).

The fan spins if pump is operational, and flashes when the pump is plugged.

7) Battery Icons: Continuously display the condition of the battery.

2-GAS to 4-GAS UPGRADE

GENERAL: D4-2002 (4-gas) BW DEFENDERS — operating toxic gas sensor

D2-2002 (2-gas) BW DEFENDERS — “dummy” sensor

The Twin Toxic sensor can be added and the BW DEFENDER programming can be

changed at any time to turn a 2-gas BW DEFENDER into a 4-gas BW DEFENDER.

Upgrade a 2-gas to a 4-gas BW DEFENDER, do the following:

2. Remove the middle “dummy” sensor and replace with a new BW DEFENDER

Twin Toxic sensor. Replace the endcap.

3. Press and hold the (ON/OFF) key. The detector will turn off. DO NOT

RELEASE THE ON/OFF KEY.

4. After 30 seconds, the BW DEFENDER will reactivate and emit one (1) or two (2)

beeps. The screen will light and the word OFF will appear on the screen. Release

the button. The User Input prompt Icons will appear at the bottom of the screen.

If the BW DEFENDER beeps once: The BW DEFENDER is password protected.

will begin showing gas measurements for all 4 measured gases.

The unit is now a 4-gas BW DEFENDER, capable of measuring toxic gases as

well as LEL and O

WARNING 1: RECALIBRATE THE UNIT IMMEDIATELY AFTER PERFORMING

THE UPGRADE. FAILURE TO DO SO WILL COMPROMISE THE

BW DEFENDER'S EFFECTIVENESS AS A SAFETY INSTRUMENT.
