9800+ 9827 Keypad AddressingControl unit pcb= 50mA quiescent.= 500mA active (when driving standardexternal bell).Each 9827 Remote Keypad = 20mA quiescent.= 40mA active.9824 Eight Zone Expander = 10mA.Standard 9066 SAB Module = 40mA.Plug-on 9056 Communicator = 40mA.Keypad WiringRecommended maximum distances for the remote keypads from the controlunit, using standard alarm cable is 100 metres for the star configuration.OutputsOP1, OP2, Bell, Strobe = 500mA. Transistorised outputs capable ofdriving a relay. Provides internal 2.2 kOhmpull up resistor.9827 Keypad AddressingBefore connecting the keypad(s) to the system, the engineer must set theaddress of each keypad. Each keypad in a system must have a differentaddress number to ensure that the control unit can correctly identify them.To set the address:1. Ensure the system is powered down. Open the keypad and identify thefour position DIP switch on the keypad pcb, see Figure 1 below. Notethat each switch is numbered 1 to 4. The numbers correspond to thekeypad address.OBSOLETE PRODUCTFigure 1. Keypad Address SwitchNote: The location of these switches may vary on different issues of the 9827.2. Select one switch and move it to the ON position (up). Make sure all theother switches are OFF (down). The keypad now has the address givenby the switch that is ON.496335 Issue 1 3 of 16
