Anti-static handling guidelines
Make sure that electrostatic handling precautions are taken immediately before handling PCBs
and other static sensitive components.
Before handling any static-sensitive items, operators should get rid of any electrostatic charge
by touching a sound safety earth. Always handle PCBs by their sides and avoid touching any
components.

Battery Information
In the event of mains failure BS 5839-9:2021 requires battery backup for 24 hours standby
and 3 hours operation thereafter.
A Beacon Master Station requires
one
12V 7AH valve regulated sealed lead acid battery. The
battery is not supplied with the Beacon Master Station.
Safety Information:
Sealed Lead Acid batteries contain sulphuric acid which can cause burns if
exposed to the skin. The low internal resistance of these batteries mean
large currents will flow if they are accidentally short-circuited causing burns
and a risk of fire.
Exercise caution when handling batteries.
Power Up Procedure:
Always apply mains power before connecting batteries. When connecting
batteries, always connect the Positive (Red +) terminal first.
Power Down Procedure
Disconnect the batteries before removing the mains power. When
disconnecting batteries, always remove the Negative (Black –) terminal first.
