1. AC Input
The two wires from the transformer are connected to these
terminals and supply power the system.
2. Network Connections
The network terminals provide connections to the remote keypads
and zone expanders. The + and – terminals provide power whilst
the R and R terminals are the data signals.
3. Zone Inputs 1 to 8
Detection devices such as movement sensors, vibration and door
contacts are connected to the zone input terminals. There are
several ways in which to wire a detection device (see page 10).
Each zone is fully programmable, see page 18 for information on
programming zones.
4. Bell Tamper Return
This terminal is connected to the tamper return connection from
an external sounder unit. If it is not required link it to 0V.
5. Auxiliary 12V
These terminals provide auxiliary power for the external sounder
and detection devices that require 12V power, e.g., moment
sensors. The auxiliary output is protected by an auto resetting
fuse (PTC) rated at 1.1 Amp).
6. Panel Outputs 1 to 4
These are fully programmable high current (1 Amp), switched
negative supervised outputs. Panel outputs 1 and 2 default to bell
and strobe operation, but can be programmed for other functions
if required, see page 27 for programming details. Each output can
also be programmed for supervision monitoring, see page 24.
Panel output 4 defaults as speaker driver and is used for driving
16Ω extension loudspeakers (see page 11). If a loudspeaker
driver is not required it maybe used as a standard output.
7. Telephone Line Connections
Telephone line connections (see page 12).

8. Power/Status LED
On steady when either AC or standby battery is present. Flashes
when the on-board communicator is dialling or sending data.
9. Communication Port 1
A serial communication port is provided for local downloading and
for third party devices.
10. Battery On (Kick Start)
When powering the system from battery only, the "Battery On"
pins must be momentarily shorted together with a plain blade
screwdriver or similar to kick start the power supply into
operation.
11. Battery Connections
A 12V rechargeable battery must be connected to these two
terminals in order to provide continuous system operation in the
event of mains failure. The battery output is protected by an auto
resetting fuse (PTC) rated at 1.6 Amp.
12. Lid Tamper Switch
This switch detects when the cover is in position and the screw is
fully secured. The tamper is designed to activate when the screw
is undone.
