15. Changing the Batteries
15.1 Keyfob
When the LED on the keyfob does not light when you press the
ON/OFF buttons, the battery may need replacing. Remove the
fixing screw and separate the casing. Ensure the replacement
battery (12V, type 23 A) is correctly fitted (check for polarity),
and replace the case. Take care not to lose the chain retaining
pin.
15.2 PIR
Sensors
If a red LED flashes behind the lens, the batteries need replacing. We recommend that you check the
batteries every six months and, if necessary, replace them (9V alkaline batteries). Note: Make sure that the
two links inside the PIRs cover only one pin (see section 12.2).
15.3 Siren
When the siren is operated normally, the LED flashes after each command. If the LED does not flash, the
batteries need to be replaced. The operational life of the batteries in the siren depends on the type of the
batteries, their use and the light conditions for the solar cells. Replace the batteries by six alkaline mono
cells of good quality.
15.4 Battery Safety Notes
-
Use only alkaline batteries of good quality. Do not use rechargeable batteries because of their self-
discharge.
-
Never insert old and new batteries together. (Always replace all batteries at the same time.)
-
Use only batteries of the same type.
-
Check that the batteries are correctly fitted regarding their polarity.
-
Always remove old or used batteries from the components.
-
Opening or burning batteries is highly dangerous.
-
Never let children play with batteries. Swallowing batteries can lead to serious health problems.
-
Do not short the battery poles.
