Always de-energize unit before removing cover.
The installation of the units must be in
accordance with any local codes that may apply
and should only be carried out by a competent
trained electrical engineer.
The power terminals on the control unit are
clearly marked and will accept up to 1.5mm
2
cable.
DC Terminals
On main PCB.
++ = Positive
- - = Negative
AC Terminals
On Sub PCB
L = Live
N = Neutral
E = Earth
The AL105N units will have the beacon already
prewired to the unit so no extra wiring is required.
4) Beacon Set-up
The beacon unit may need to be configured
dependant on the type of flash required.
The xenon beacon has a 1Hz flash rate only.
The LED beacon is set as standard to the 2Hz
flash mode but it can be set to a steady on mode
also. To alter the settings, change the position of
the header pin as shown.
•
Remove header for steady mode.
•
Keep header in standard position for
2Hz flashing mode
5) Unit Set-up and Recording
The unit will need to be configured to suit the end
user.
If recording either via the onboard microphone or
the in-line connector the unit will need to be
supplied with power.
DC units can be powered when completing
recording and set-up.
Warning! : During set-up AC units must be
temporarily powered from either a 12V battery
or a separate 10-30VDC isolated power supply,
connected directly to the DC terminals on the
main appello PCB. This is because the AC
units power supply is not isolated and there
may be a risk of electric shock.
See section 7) Appello Setup Guide overleaf for
Set-up instructions and functions.
6) Tone Selection Table
The Appello unit has 45 different tones (See
Table 1) that can be selected for the first stage
alarm. The systems can then be switched to
sound second, third and fourth stage alarm tones.
The tones are selected by operation of a DIP
switch S4 on the main PCB.
The tone table (Table 1) shows the switch
positions for the 45 tones and which tones are
available for the second third and fourth stages.
Example

Shown Set for Tone 1
(All switches OFF)
To sound stage one simply connect the supply
voltage (+ve and
–ve) for DC units and (L, N, E)
for AC units, to the supply input terminals on the
correct PCB shown.
