SDI2 address settings

Notice!
The module reads the address switch setting only during module power up. If you change the
setting after you apply power to the module, you must cycle the power to the module in order
for the new setting to take effect.
If multiple B520 modules reside on the same system, each B520 module must have a unique
address.
6.2.2

Supervision

The control panel supervises any B520 on the SDI2 bus.
With any failure to receive an expected response from a B520, all keypads show a system
fault. The control panel sends a module trouble report to the central station (if configured for
module trouble reports).
6.2.3

Auxiliary power supply trouble conditions

Each auxiliary power supply module on the SDI2 bus monitors several conditions including AC
status, battery status, over current status, and a tamper input. Each of these conditions
produces a unique system trouble condition at all keypads. The control panel sends a module
trouble report to the central station (if configured for module trouble reports).
