Panel Relays
The panel is equipped with four programmable relays, each capable of supplying 500mA. The total
current draw across all four relays must not exceed 1A. The default relay types are:
Relay 1: Fire Routing Relay
- This activates on an alarm condition. It switches 12V onto the output and
is monitored for short and open circuit, with a 4K7Ω EOL. The circuit should be connected between the
C and the NO terminals. The fuse should be fitted and the links put in the lower position.
Relay 2: Fault Failsafe Relay
- This energises on power-up and de-energises in fault. Consequently the
normally open and normally closed terminals are reversed. The fuse should be removed and the links
fitted in the upper position as shown on the PCB layout diagram.
Relays 3 & 4: Sounder Circuits
- These are each capable of supplying 500mA at 12V. Both the sounder
circuit fuses should be fitted in the fuse holders and the links fitted in the left or lower positions as
shown on the PCB layout diagram. The circuit should be connected between the S+ and the S-
terminals. A 4K7Ω end of line resistor should be fitted to monitor the circuit.
The relays can be configured as sounder circuits, monitored outputs or volt free clean contact relays.
The relay type can be changed in 6.8 – User Options and by positioning the jumper links and fuses as
detailed below. When relays are configured as fire routing or as sounder circuits, the associated
terminal pin (V+)
must not
be used.
Only the default relay types have been type approved.
Display Cable
A ribbon cable connects the two panel boards together. It should be connected to the system link/bus
connections on the boards.
Do not remove or connect the ribbon cable while the panel is powered
up, as damage can occur to the processor board.
Buzzer Link
The buzzer can be disabled by removing the buzzer link (see page 6 – PCB Layout). Note that when the
buzzer is disabled, the system will not comply with EN54.
Memory Card
The memory card stores a complete set of the system settings including device/zone text and options.
The memory card should be fitted at all times unless instructed by the panel (i.e. when adding a
repeater panel).
USB Socket
The USB socket can be used for connecting a keyboard to program device text. It is also used to plug in
a memory stick to download the event log, device info and the verify table so a hardcopy can be
retained for records.
