(item 3) is located next to the mains terminal block, which in turn is wired to the
power supply unit.
The front door of the panel is electrically connected to mains earth via earth
straps.
When connecting the mains supply to the panel, make sure that the incoming
power is from a clean source that has a solid earth connection. Connecting the
panel to a secure earth is very important.

Make sure that the mains supply wiring is correctly connected. The wiring should
be as short as possible within the panel and should be kept away from Z-loop
wiring, data cables, and other low voltage wiring.
Mains power should be sourced directly from a separate circuit breaker in the
building electrical supply distribution board. This circuit should be clearly marked,
have a bipolar disconnect device, and only be used for fire detection equipment
See Figure 39 on page 52. The 24 VDC output (“Supply Output” terminal, TB2 on
the main board) is for use by auxiliary equipment, such as programmable relay
boards, sounder driver boards, etc. It can also be used to provide power to
devices such as remote display units, and similar peripheral devices.
