2. Charge batteries overnight before using them
3. On larger systems, power PIRs from a separate PSU
4. Make sure PSUs come off the same phase / Earth mains supply
5. Always eliminate induced AC by fitting a 12V spike suppressor

Alarm Cables

7. Connect unused spare wires down to Earth
8. Always use screened cable for keypads, LIMs and iD circuits
9. Never run data and sounder circuits in the same cable
10. Use insulated staples in staple guns
11. Always solder twisted joints on EOL and iD circuits

PIR Detectors
12. Choose PIRs fitted with genuine white light filters

14. Avoid placing PIRs close to radiators, fireplaces and boilers etc

19. Fit a PIR stabiliser to prevent false alarms caused by RFI
