Every security system must-have: Fallback power switches

In this security-conscious age, webcams, motion detectors, and badge scanners have become increasingly common elements in most businesses and public facilities. It doesn’t matter if you’re checking ID cards, observing activity in a lobby or community space, or monitoring a building during off-hours for suspicious activity; most mission critical security applications rely on the sort of constant vigilance that can only be supplied by a monitoring device, ID scanner, or electronic sensor.

An intelligently planned electronic security system can monitor badge-in/ badge-out activity, detect movement in buildings during non-work hours, generate alarms when doors are opened in secure areas, and keep watch over huge buildings without the need for regular patrols by ever-present security personnel.

But as useful as these devices are, it’s important to remember that many electronic sensors and monitoring devices do not include power fallback capabilities, and as such, they can often be rendered useless by a simple power interruption. This means that even if your security solution includes the most advanced equipment available, without a reliable power fallback solution, your building can still be left unprotected during a power outage or blackout—or when external power to the security system has been purposely defeated.

If your security system or access control application lacks an effective power redundancy solution, fallback power switches can provide fast, reliable power fallback capabilities, without the need to replace existing single power inlet devices with new, dual-inlet devices. The switches can help to minimize or eliminate downtime for your security system by ensuring that even when your main power source is not available, the security system can automatically switch over to a back-up power source almost instantaneously.

Installation of a fallback power switch is simple. No switch configuration is required; just connect the fallback power switch to your primary and secondary power supplies and then connect your single inlet security devices to the switch’s outlets and you’re ready to go.

Once installed, the switch will continuously monitor the power source, checking for instability or other trouble signs. If power to the fallback power switch is interrupted, it can quickly switch to the back-up power supply, providing nearly seamless power switching with switchover times less than 16 milliseconds—fast enough that the switchover is generally undetectable by most devices. Later, if the switch determines that the primary power supply has been restored or stabilized, it can also automatically switch from the secondary power supply back to the primary power supply, making it an intelligent power redundancy solution for single-inlet security devices.
