关于此计算器
How this is calculated
The tool sizes the standby battery for a fire alarm panel to NZS 4512:2010 Clauses 212 and 213. It sizes the capacity only. It does not pick the battery type.
- Standby capacity. It multiplies the non‑alarm load by the standby period.
- Alarm capacity. It multiplies the alarm load by the alarm period. It compares your period with the period in Cl 213.1 and uses the longer.
- Factors. It adds the standby and alarm capacity. It multiplies by your ageing and temperature factors.
- Minimum. It also reads the minimum capacity before factors. The larger figure governs, and the tool names it.
- Charger. From Cl 212 it gives the charger current to restore the battery in 24 h. It also gives the float voltage and tolerance for your cell count.
- Monthly test. From Cl 602.7 it gives the minimum voltage the battery must hold in the monthly test.
| Step | Table or clause | What it decides |
|---|---|---|
| Capacity | NZS 4512 Cl 213.1 | Standby and alarm capacity, with factors |
| Charger and float | Cl 212 | Charger current and float voltage |
| Monthly test | Cl 602.7 | The minimum voltage in the test |
| Service life | Cl 213.5 | The minimum life of the battery |
Worked example
A panel with a 0.5 A non‑alarm load and a 3 A alarm load. The alarm period is 30 min. The system has 12 cells and is monitored. The tool gives 16.88 Ah at 20 °C. The charger current is 1.2 A. The float voltage is 26.4 V.
Limits
- NZS 4512:2021 supersedes the 2010 edition this tool reads. Check the current edition.
- The tool does not check the battery type or the service life.
- It does not add up the load of each device. You enter the totals.
- It gives the capacity at 20 °C. Enter a temperature factor for a cold or hot room.

火灾报警蓄电池工具有什么作用?
本工具将火灾报警控制盘在待机期间消耗的安时数与报警期间消耗的安时数相加,再应用老化系数和温度系数,并报告 20 °C 下的容量。
火灾报警蓄电池须维持多长时间?
有监控链路时,AmpSize 采用 24 小时待机;无监控链路时采用 72 小时。随后加入 30 分钟报警负荷。这三项数值均来自 NZS 4512:2010 Clause 213.1。表单选项可在两种待机时长之间切换。
结果能否低于 Clause 给出的数值?
否。Clause 213.1 和 Clause 213.2 规定了最短时限。AmpSize 在应用系数之前,按条款报警时限与您输入时限中较长者计算最小容量,且不会报告低于该值的结果。报警时限过短时,将给出警告。
它报告的充电器和浮充电压是多少?
AmpSize 将容量除以 24 小时,并加上非报警电流。由此得出 Clause 212.1 的充电器电流。它还将 2.20 V 和 0.03 V 乘以电池节数,用于 Clause 212.5 的浮充区间。
每月测试的判定标准是什么?
Clause 602.7 以 5 小时放电率或更高倍率对蓄电池进行 10 秒测试。测试期间,蓄电池不得获得其他电源的支持。其电压不得低于标称电压的 80%。
