Mount a Backup Battery (optional)
If the installer chooses, a backup battery may be mounted in the EverAccess
enclosure and connected to the controller to provide backup power in the event of
external power loss. Once the battery is installed, it will charge off the external power
until it is needed, at which time it will automatically be used to power the system.
Connection to Backup Battery
Connect the positive end of the backup battery to terminal 20 and the negative end of
the backup battery to terminal 21, as shown in Fig. 4.2.
Fig. 4.2 Connection to Backup Battery
If a backup battery is connected, the controller will automatically switch to backup
power in the event that the external power is lost. The backup battery will charge
while external power is being supplied.
In general, the larger the battery capacity is, the longer it can support the controller.
Roughly speaking, a 12AH battery can provide 4 hours of energy for a controller
containing 4 door modules, 1 alarm modules and 8 card readers.
Reset Controller
Before turning the power on, please double check to ensure that all the wiring and
connections are correct. In order to restore factory default settings, switch the power
on while holding down the RESET switch. The RESET switch is shown in Fig 4.3
