Practical Calculations and Examples (South Africa Context)

Battery Backup Sizing

Gauteng's load shedding makes backup battery selection vital. Alarm kits often use a 12V sealed lead-acid battery. To calculate backup time:

*Estimate only. Actual runtime can be affected by sensor activity, siren use, and battery age.

Typical Installation Steps

1. Mount control panel, sensors, and siren according to included instructions.
2. Connect backup battery (observe polarity: red for +12V, black for ground).
3. Test all sensors and zone functions via the keypad or mobile app.

Many kits support wireless pairing through simple programming sequences on the keypad, making expansion straightforward. Students and hobbyists can use these starter packs for practical electronics projects or demonstrations.

Troubleshooting Tips

• If siren won't activate, check wiring, battery voltage, and fuse condition.
• For false alarms, reposition PIRs away from fans/vents and direct sunlight.
• Lost zone: re-pair or check contact/magnet alignment on windows/doors.
