Calibrate, bump test, and inspect the detector on a regular schedule.
l
Maintain an operations log of all maintenance, bump tests, calibrations, and alarm events.
l
Keep the exterior of the detector clean.

and Technology.
l
Verify the expiration date on the cylinder before use.

Do not use an expired gas cylinder.
l

Charge the Battery
You can charge the battery using the provided charging adapter, that is certified for
SELV/LVLC (isolated) with an output Um of 6.3 V.
It can take up to 8 hours to get the battery fully charged in a temperature range from 5 °C to 35
°C.
Note: If you charge with the power on, charging may not be completed within 8 hours.
Maintain the Battery
Lithium-ion batteries do not respond well to cycles of full discharge followed by a full charging
cycle. Recharge the battery before it is exhausted.
Do not charge the battery at low or elevated temperatures. 30°C (86ºF) is considered an
elevated temperature and should be avoided whenever possible.
A rechargeable battery’s runtime decreases approximately 20% over a two-year period of
typical use.
