Why use a protected power distribution module in your security system?
Redundancy – Fire Protection – Cost Savings
A fused power distribution module (PDM) adds resilience, compliance and peace of mind to your security system, all while saving costs.
Redundancy.
Relying on overcurrent protection from a single source, such as a power supply fuse, is a poor practice. Accidental or malicious cable damage to a single system component, such as a PIR or lock, could take down an entire security system.
A security PDM provides a fuse for each component and allows most of the system to keep working even if one part suffers from a cable fault or short circuit.
Fire Protection.
Exceeding the current rating of a security cable leads to heat, which leads to melted cables and potential fire. Various security cables have different ratings. Overcurrent protection should be tailored to these ratings.
For example, a typical four-core security cable has a maximum current rating of 2A; most security power supplies can provide much more current than this and will happily do so while the cable overheats.
A PDM helps installers add overcurrent protection that matches cable ratings and load requirements. A 50-cent fuse is a lot cheaper to replace than 50m of damaged cable.
Cost savings.
A PDM is easier to install (and replace) when compared to a mess of separate relays and terminals. LED indication, circuit separation and consistent layouts also make fault finding more efficient. A PDM is easier to check during fire tests and routine maintenance.
Security PDMs are a no-brainer, but still often get overlooked during installation. Jack Fuse Power Port PDMs are designed for electronic access control & security systems and include options for automated fire trip and self-healing fuses.
