Worked examples for fire alarm batteries, loop loads, DIP switches, CCTV storage, UPS, and access control planning.
Sample inputs: standbyCurrent: 1.8; alarmCurrent: 5.5; standbyHours: 24; alarmMinutes: 30; derating: 80; spare: 20
Use at least 75 Ah battery capacity based on the entered standby, alarm, derating, and spare values.
Run calculatorSample inputs: detectors: 82; modules: 18; sounders: 12; detectorMa: 0.35; moduleMa: 0.6; sounderMa: 4.5
The loop is at 18.7 % current usage and 44.8 % address usage under the entered assumptions.
Run calculatorSample inputs: fireSystem: zeta; address: 37
For ZETA, set S1 ON (1), S3 ON (4), S6 ON (32) for address 37. Verify the device manual before site programming or commissioning.
Run calculatorSample inputs: cameras: 64; bitrate: 4; days: 30; hours: 24; raid: 15; spare: 20
Plan approximately 111.97 TB usable storage for the entered retention period.
Run calculatorSample inputs: equipment: 1800; poe: 950; network: 350; spare: 25; runtime: 60; upsPf: 0.9
Use around 5 kVA UPS capacity before selecting actual battery configuration and runtime package.
Run calculatorSample inputs: doors: 11; readersPerDoor: 2; controllerCapacity: 4; lockWatt: 6; voltage: 12; backup: 4
Plan 3 controller(s), 22 reader(s), and at least 6.60 A PSU capacity for the entered door hardware.
