Any Grade 3 Invincibell has an output on the PCB called ‘FAULT’, this is used to monitor the SAB back up
battery. This output does not need to wired to Grade 2 panels.
The Invincibell will do an active self test on the SAB back up battery every 24 hours. If the SAB back up
battery fails it’s self test, then the FAULT relay will open and notify the control panel of a ‘Warning Device
Fault’. It may then be necessary to replace the SAB back up battery.
The Invincibell siren trigger wire input must also be monitored to be compliant at Grade 3. On some control
panels it may be necessary to connect a resistor between the control panel siren output and 0V or 12V.
Refer to the full manual for Pyronix and Castle connections, for all other control panels please see the below
diagrams that show the Grade 3 connections on various manufacturers’ control panels.
Note: If using 2 Grade 3 Invincibells please do not parallel the bell trigger wire. Always use a separate
output. Strobe trigger wires can be wired parallel.
When wiring an Aritech ATS 2003 3003 4003 the bell trigger wiring must be wired through a relay, as
shown in Figure A on page 2.
