GETTING STARTED POWER

GENERAL: Familiarize yourself with all operating features and functions of the

BW DEFENDER. The BW DEFENDER is calibrated at the factory. User selectable

Alarm Setpoints have been set to relevant safety standards. The BW DEFENDER will

advise the current Alarm Setpoints each time it is turned ON. If the user wishes to

reset the Alarm Setpoints, refer to “ADJUSTING ALARM SETPOINTS”.

BATTERY AND CHARGER: Batteries must be charged before use.

WARNING: ONLY CHARGE BATTERIES USING A BLACK & DECKER

VERSAPAK™ CHARGER. DO NOT USE ANY OTHER CHARGER.

FAILURE TO OBSERVE THIS PRECAUTION COULD LEAD TO FIRE

OR EXPLOSION.

CAUTION: READ AND OBSERVE ALL INSTRUCTIONS AND PRECAUTIONS IN

THE BLACK & DECKER LITERATURE PROVIDED WITH THE

BW DEFENDER. FAILURE TO DO SO MAY RESULT IN FIRE,

ELECTRIC SHOCK OR OTHER FORMS OF PERSONAL INJURY OR

PROPERTY DAMAGE.

FIRST TIME CHARGE:

The charger supplied with the BW DEFENDER is a VAC

2-port charger, which requires approximately 6 hours (both batteries) for

a first time charge.

NORMAL CHARGE TIME: After the first use, battery charging times decrease.

Normal charge time:

2-port VAC Charger - 3-4 hours for 1 to 2 batteries

Black & Decker VERSAPAK™ chargers (other than the 2-port charger included with

the BW DEFENDER) may be used with BW DEFENDER batteries. Refer to the

instruction manual provided with the specific charger unit for charging instructions.

NOTE: Batteries can be left in the VAC charger until required for use.

OPERATING SPECIFICATIONS

Operating Humidity: 15 to 90%

Operating Pressure Range: Atmospheric ±10%

Note 1: Response typically less than 2 seconds @ T

Note 2: All performance data is based on conditions a 20°C (68°F), 50% RH and

1013 mBar (1 atm)

CAUTION: The BW DEFENDER combustible sensor is highly poison resistant. All

catalytic sensors should be protected from exposure to lead compounds,

silicones, chlorinated hydrocarbons. Certain organic vapors (e.g. leaded

gasoline and halogenated hydrocarbons) may temporarily inhibit the

sensor performance, in most cases it will recover after calibration.
