3. SETTING UP THE SYSTEM.
The Alarm Keypad is set up in three stages; RCB Installation (section 3.1), Alarm Keypad Wiring (section
3.2), and Software Setup (section 3.4). The first time the system is installed, it may require some further
configuration of a file (section 3.3), but this stage should only need to be done once.
3.1 Installing the RCB
The Redundant Communications Bus (RCB) kit comes with two small microchips and a two-port, green
terminal block. To install these, use the following procedure:
1)
Turn the power off to the controller. This is vital, as leaving the power on may damage the components
2)
Carefully mount the two chips into their slots in the lower right of the board. The larger should clip easily into U29 and
the smaller into U30. Be careful to ensure they are installed the right way around, so that the semi-circle on the chip
matches the semi-circle on the housing. Note that you may have to bend the legs slightly to ensure a snug fit
3)
Clip the green terminal block into its place at the bottom right of the board (J10), with the ports facing down
4)
Turn the power back on
Great care should be taken when handling the two chips; they are extremely sensitive to static electricity and
are very easy to damage, both physically and electrically.
Never force the chips into their housing sockets; they should clip in easily and snugly. If they will not go in,
examine each leg in turn to see if any bending is required. It is also an idea to handle the chips as little as
possible, and, if you are installing in an area with high static – such as nylon carpets – you should touch
something metal before handling the chips in order to dissipate any charge that has built up.
3.2 Wiring the Alarm Keypad
Once the RCB chips and terminal block are installed, you need to ensure that everything is correctly wired.
The wiring configuration for the controller and any reader(s) you may wish to add can be found in the
relevant documentation for those products, and so does not need to be replicated here.
To wire the Alarm Keypad, turn the unit over to expose the white terminal block on the rear. There are four
ports here, which should be wired as follows:
Alarm Keypad:
Controller:
AUX (RED)
12V DC
COM (BLK)
0V
BUS (YEL)
H2 (RCB terminal J10)
BUS (GRN)
L2 (RCB terminal J10)
Note that although the 12V DC power can come from the main power terminal (J7) on the controller, we
instead advise that it comes from the small PSU (Power Supply Unit) board that sits to the left of the
controller in the metal case.
You may also like to take this opportunity to check the dipswitch settings. Turn the unit over and lift the
backplate away by depressing the two plastic clips at the bottom of the panel. Once away, use the two
plastic clips at the bottom of the circuit board to lift the whole board out. You will see a bank of 4
dipswitches housed in a blue case on the circuit board. Ensure that all 4 switches are set to OFF, then
carefully reassemble the unit by putting back the board, clipping it into place, and then returning the back
cover.
