through the on-board electronic output, must be of SELV (Safety extra-low voltage)
operating circuit.
•
Use a relay with good insulation between the contacts and the coil.
•
Place a suppression diode, for example, a 1N4001, across the relay coil.
•
Relays connected to open collector outputs of the alarm system should be rated
at 12 volts DC with a coil impedance greater than 400 Ohms.
5. The remote bus cable is used for communication between the control panel and the
keypads/expanders. The greatest care should be taken when installing this cable.
Never split it into separate cables. Do not use cables with wires that are used for
telephone connections or for switching, for example, flashing LEDs, sirens or relays.
6. Avoid cable ducts and cableways that contain mains power cables. This is
particularly important when such ducts contain cables supplying electric motors,
fluorescent lights or three-phase power. If this is not possible, shielded cable should
be used and the cable should be earthed at the control panel end only.
7. If the upper and/or lower cabinet entry cable holes are used to route wiring into the
control panel, always use a proper pipe fitting system by means of appropriate
conduit and junction box. Use only materials of suitable flammability class (HB or
better).
8. For mains power connection, use the mains connector terminal either through a
permanent wiring or a flexible mains cable to an earthed mains outlet. Always use
cable ties to fix mains cable at the dedicated fixing point provided near the mains
terminal connector.
•
For permanent fixed wiring, insert an easily accessible, dedicated bipolar circuit
breaker in the power distribution network.
•
Do not solder the end of a stranded conductor at places where the conductor is
subject to a contact pressure, unless the method of clamping reduces the risk of
a bad contact due to cold flow of the solder.
4.3 Basic
installation
procedure
You should first identify a suitable place for the control unit. This must be convenient to a
mains supply and a telephone connection.
You must then:
1. Mount the sensors, keypads, control unit, smoke detectors and sounders.
2. Connect all modules and keypads to the keypad bus, making sure to set the DIP
switches on the modules and record the module addresses. These are needed
later.
3. Connect the battery and the mains power. The control panel will not start if only
the battery is connected.
4. Program all keypads with their keypad number and partition number using
94
.

Setting keypad options
on page 40 for more information.
5. Set the options on each keypad.
6. Once all keypads have been programmed, you can either enter and exit
programming mode to initialise the modules and keypads, or continue by
