95EN, 85EN, 65ENZone Wiring (Optional)The keypad can support two fully-supervised loop zones (CCL/double-polewiring not supported). Contacts are normally closed; if normally open,program zone with the "Inverted" attribute.Note: If you are powering the sensor from the keypad (see page 3 for poweravailability figures), an additional two cores are required for connection to theA (+12Vdc) and B (0V) terminals.100 Ohmsmax.4K7AlarmTamper2K2FSL enables supervision of cabletampers. The resistors can take anyof the following values (specify thevalues when programming the zone).Alarm ShuntResistor4k71k04k72k2End-of-LineResistor2k21k04k72k2Anti-MaskWiring:100 Ohmsmax.2K2Anti-mask4K7AlarmIf the sensor has an anti-maskingfacility, a single zone using threeresistors can convey all states (healthy,alarm, masked and tamper). The zonecan be programmed as any type (e.g.Normal Alarm), but must have the"Masking" attribute.Tamper2K2The PROG link must be fitted foranti-masking.Figure 32. 9950/9951/9953 Zone WiringOutput Wiring (Optional)You can connect an output device across the A (12Vdc) and O/P terminals.By default, "O/P" is normally at 12Vdc, and switches to 0v when active. Thesense can be inverted when programming the output. Examples of outputdevices include a 12V buzzer, LED (fitted with a 1k0 resistor in series) andrelay (fitted with an IN4001 diode across the relay contacts).Loudspeaker Wiring (Optional)You can connect a single 16 Ohm loudspeaker across the B and SPKRterminals. The loudspeaker follows the internal sounder. The volume isadjustable using VR1.Setting the AddressSet the address of the keypad to 1, 2, 3 or 4 by fitting the jumper across theappropriate link, or set to address 5 by leaving the jumper off.
