Connection to power supply
Radio module 1058/010 takes power supply at 12 V— out of wired alarm control panel it is connected to.
Before making the connection, check for wired control panel to be able to provide current requested by
radio module, that is that overall absorption of control panel, devices, connected to control panel, and radio
module does not exceed the current which control panel power supply unit is able to supply
Power supply cable must be connected at one side to pins + and – of radio module and at the other side to
wired alarm control panel 12 V— output. In connection, observe polarities!
Warning:
wired control panel side connection must be downstream of control panel power supply unit and
backup battery to assure radio module 1058/010 power supply also in lack of network power supply (230 V).
NOTE:
should control panel not have a current reserve sufficient to supply radio module 1058/010 too,
radio module 1058/010, can also be supplied by an additional power supply unit provided with a backup
battery, such as 1063/091.
