8.1.6 Solar siren
If you must power down the system completely, first switch the control panel into test mode and then switch the siren into
service mode before removing the siren cover and disconnecting the rechargeable main battery and the initial power-up
battery. Make sure that the solar panel is covered with a lightproof material to prevent the solar panel from powering the siren.
After installing the siren, switch the siren back into operating mode to re-arm the siren.
1. Clean the solar panel using a soft, damp cloth every 6 months, preferably in spring and autumn. Do not use abrasive,
solvent-based or aerosol cleaners. Do not clean the inside of the siren or allow water to enter the siren to make sure that
the solar panel keeps receiving all the available light.
2. Do not leave the siren for long periods with the batteries connected, unless the siren is able to receive sufficient light to
maintain the battery charge. If the battery charge is not maintained, the rechargeable main battery will run unacceptably
low and the siren must be recharged from the 12Vdc/1A power supply of the control panel. Install a new initial power-up
battery to make sure that the siren receives sufficient power until the solar panel can recharge the main battery.
3. Do not leave the rechargeable main battery in a discharged state for long periods. The rechargeable main battery has a
typical life of 3-4 years and does not require any maintenance.
Replacement batteries: 7.2V NiMH battery (1x) / 9V PP3 alkaline battery (1x)
