How healthy is your Alarm system’s heartbeat?

With the current peculiar weather patterns placing a lot of additional strain on our electrical grids, load shedding is going to be on the rise once more.

Besides the inconvenience to you what else does this mean to you and why should you be concerned from a security point of view?

Installing a complete alarm system into your residential or commercial property has already cost you a pretty penny, to make sure that it doesn’t cost you any more additional unnecessary expenses , here is some friendly advice on how to keep your system in tip top shape.

The Battery/ power supply, essentially the heartbeat of your whole system, during the frequent power outages, the system has to rely solely on the battery to keep it operational. When the power is restored quite often there can be a power surge that follows the restoral. A fairly inexpensive option with this is to plug your alarm systems power supply into a good quality surge protection plug before going into the socket by the wall.

Another thing that one has to be aware of is that when the power is down the battery is the only source of power for your whole system to continue operating. Many people take the standard offered 3AMP battery that  comes recommended when you have your system installed , however is that a big enough size battery to run the system , if you have outside protection- to run that too and still operate your garage door . That’s a fairly large amount of strain to place on 3AMPS.Conssider upgrading your battery to bigger amperage.

One also has to keep in mind that while the power is off your battery is discharging, once the power is restored the battery starts charging again. If you are having multiply outages in a day, this is not giving the battery time to fully charge between each outage.

 Each time a battery discharges completely, the plates inside corrode and little pieces break off. This is called deep discharging. Most modern gate motors and computer UPS’s have built in circuitry to prevent its battery from discharging below a certain point. Battery manufacturers estimate that 5 to 10 such deep discharges can occur before the battery sustains serious damage.

Of course this depends on the number of sensors and keypads drawing power from your alarm system battery, but the sad news is that yes, load shedding does send your alarm battery to an early grave, so be prepared to replace your battery much earlier than a few years of use. Depending on Eskom’s schedule, perhaps after only a few months.

The first sign of an alarm battery failure is usually a beeping keypad, therefore it is imperative to test the battery (if you know how, you can do it yourself) or phone us to test the alarm battery for you. You do not want to be unprotected!
