NOTES:
y
The control panel power supply unit has been designed for work with lead
batteries or other batteries with a similar charging curve (European Directives
91/157/EEC and 83/86/EEC).
yIt is impermissible to connect a fully discharged battery (voltage on terminals
without a load less than 11V) to the alarm panel. To avoid hardware damage,
fully discharged or never used battery should be charged initially using proper
charger.
IMPORTANT: The SATEL Company recommends that operation of the whole alarm system be
regularly tested. However, a reliable alarm system does not prevent burglary,
assault or fire from happening, it only diminishes the risk that such a situation
will cause no alarm or notification.
