The battery starts working when there is a power outage. Frequent power failures and power spikes tend to deteriorate the lifespan of batteries. Intelligent alarm systems communicate with the control room of the security company. When an alarm system battery starts running low, it sends a signal to the control room where the alarm and security systems are monitored. Once the battery is fully discharged, the alarm and security system are no longer working and no further signals are received in the control room. Once the power is back up again, the battery is recharged.When the back-up battery comes to the end of its life, it starts to malfunction and could cause false alarms. Such batteries need to be replaced immediately.Typical “General purpose” batteries used for this market were not designed for regular and long power outages such as load shedding or power grid failures. Rentech offers a range of batteries with good performance suitable for standby applications to ensure your alarm or security system is always available.
