The damage caused by Fire is potentially one of the greatest risks any business can face. Over 70% of businesses involved in a major fire do not recommence trading or the business fails within 3 years of the Fire. Accidental fires and arson costs industry many millions of pounds in lost revenue and insurers multiples of millions in claims.

The installation and maintenance of a Fire Detection system is vital to the protection of Life and Property, with early detection, every second saved may assist in the recovery due to minimizing the destruction. In the 12 months to June 2006 the number of false fire alarms increased by 2% to 477,700, although this is 6% lower than the peak of 507,000 in 1995. Within this category the number of false alarms due to apparatus rose by 4% to 281,800 and malicious false alarms fell by 3% to 70,200. The economic cost of false alarms to businesses and the Brigade alike are high and the risk to potential loss of life immeasurable.

Enter the Quiescent load & Alarm load figures in the above fields in milliamps eg 1/2 amp = 500ma, 1 amp = 1000 etc. This form uses the standard BS5839 battery calculation formula.

Example Battery Formula & Calculation Completed By This Tool

Assume standby load of 250mA, alarm load of 750mA and a standby period of 24 hours with 30 minutes in alarm condition:

Cmin = 1.25((24 x 0.25) + 1.75(0.75 x 0.5))

= 1.25((6 + 0.66))

= 8.32 Ah
