PA buttons may be fitted near the front door, or
in a bedroom.
Extension speaker
Extension speaker may be connected to the
loudspeaker terminals to produce high volume
alarm tones and low volume entry / exit fault
tones.
Up to two 16 ohm extension speakers may also
be wired across the speaker terminals. Mounted
in convenient positions within the installation
the extension speakers will reproduce all of the
alarm tones generated by the control panel.
A control marked VOLUME in the centre of the
PCB may be used to adjust the low volume
entry/exit tones to suit environmental conditions.
To adjust this control, partially lift up the top
cover.
Bell Output (External sounder)
The bell is usually installed in a high position
from where the bell could be seen and heard.
Terminal T A D B are for connection to the
external bell or sounder. These terminals
provide a power/hold-off supply, sounder
trigger and tamper circuit to protect the external
sounder housing.
The terminals are summarised as follows:
T -
-Ve tamper return
A -
-Ve supply (0V)
D -
+Ve supply (12V)
B-
-Ve Sounder trigger
For ease of installation, ADE sounders and
modules use the same markings.
Where a discrete bell sounder is used, it should
be connected to terminals D & B. Terminals T &
