Why Fuse?
Overcurrent protection of security power cabling is mandated in the Australian Wiring Rules, AS/CA S009:2020.
Fuses help prevent fires and equipment damage as well as providing system redundancy and therefore are a vital component of every installation.
It is a common misconception that you use a fuse to protect your downstream field device such as an electric lock or motion detector. This is incorrect. If an overcurrent situation occurs at a field device then it is likely caused by damage or incorrect installation. A fuse back in the security panel can’t prevent damage to the field devices but will help protect other equipment.
Fuses are used to protect the field cable and upstream devices such as power supplies. This is a vital function. When a field device fails or a short circuit is placed on the cable, the current supplied will become very high and, without protection, it will cause damage to cable, the power supply and the security controller.
Fuses also provide redundancy by limiting damage to smaller parts of the system. An installation with no fuse is susceptible to complete failure due to an overcurrent fault. Add in a well designed fused power distribution solution and damage will be limited to one system component, allowing others to keep functioning.
