The LP-1 becomes an uninterruptable power supply when used with a transformer and stand by battery.  The output of the LP-1 is a clean smooth continuous DC power which can be used to power the most sensitive electronic controls.

The LP-1 output and battery charge voltage is selected by moving the programming jumper to 6V, 12V or 24V.  The voltage selected is factory preset to precisely charge a Sealed, flooded, or Gel Type Lead Acid Battery(s).

The current that the battery draws from the LP-1 is determined by the battery's condition, capacity, temperature and state of charge.  The LP-1 is protected against shorts and overloading with its electronic circuitry and battery fuse.  This same circuitry also protects the transformer.  When the DC load requires more than the maximum output provided by the LP-1, the battery can add up to 4 more amps.

This may be necessary to sound a high powered siren for the duration of an alarm.  The LP-1 has a replaceable 4 amp battery fuse or optional automatic resetting 2 Amp circuit breaker.

For calculating standby current, recharge times, and available current, refer to the tables and the specifications on the backside of this bulletin.

To test the battery and fuse: It is recommended that on a regular basis, the output should be checked for proper voltage and current while the AC power is removed.

Output DC Voltages are optimized for Sealed Lead Acid or Gel Type Battery Charging.

Caution: Select your output voltage before connecting AC.
