SPECIFICATIONS & FEATURES
DIP SWITCH SETTINGS:
Each Annunciator needs to be assigned a unique, sequential
“Address”
. This is done with DIP Switches, which also
allow disabling of some buttons.
SW1-1
=
Address A0
\
SW1-2
=
Address A1
>
Address “A3” is always “off”.
SW1-3
=
Address A2
/
SW1-4
=
When “off”, the System Reset and Signal Silence slide-switches are always disabled, regardless of the
operation of the keyswitch.
The Annunciator “Address” (see the Manual for the Fire Alarm Control Panel being used), is set as ...

Annunciators on a common RS-485 connection must be numbered sequentially; i.e.: 1,2,3,4, and not randomly
such as 5,3,7 !! Note that not all Annunciator “Addresses” are valid for all Fire Alarm Control Panels. Refer
to the Fire Alarm Control Panel Manual for further information.

The
Normal Standby Current
is used for Battery Size Calculations (see the Fire Alarm Control Panel manual) and includes
the current drain for the Trouble Buzzer, Trouble LED, and one Alarm LED. The
