Abstract
An alarm system with improved power is provided. The improved power comprises at least two batteries. Each battery has the capacity to individually back up the alarm system for a standby period. The alarm system selects either battery and operates from that battery. A switching network is coupled to a power source and to the batteries. The switching network is capable of transferring one battery to charge and the other battery to discharge, with the discharge battery providing power to the alarm system. A battery charger circuit is powered from a power source. The battery charger circuit is used to charge the battery that is not powering the alarm system. Circuitry and software can be provided to monitor the health of the batteries.
Claims26
An alarm system comprising:
- at least two batteries, the alarm system selecting a battery and operating from that battery, each battery having the capacity to individually back up the alarm system for a standby period;
- a battery charger powered from a power source;
- and
- a switching network coupled to battery charger and to the at least two batteries, the switching network being capable of transferring one battery to charge and the other battery to discharge, the discharge battery providing power to the alarm system, and the battery charger used to charge the battery that is not providing power to the alarm system.
A method of providing power to an alarm system comprising:
- providing at least two batteries;
- selecting a battery and operating the alarm system from that battery;
- when the battery operating the alarm system reaches a discharge level, switching the batteries so that a previously charged battery is now operating the alarm system;
- and
- recharging the previous battery operating the alarm system.
A method of monitoring power in an alarm system comprising:
- providing a battery to operate the alarm system;
- alternatively charging and discharging the battery, the discharge of the battery being used to power the alarm system;
- and
- monitoring the charging and discharging of the battery.
