System 2 Installation / Programming Manual

Transformer and Battery

Transformer

The main power source for System 2 is a UL listed transformer. Primary 120V, 60hz, .48A / Secondary

16.5VAC, 40 VA. If the 16.5VAC output terminals are shorted, the internal fuse will open and the

transformer will be useless. It should be noted that the fuse is impossible to repair. Attempting to repair it is

dangerous and also voids the UL Listing! The transformer measures 2.75" x 2.625" x 3.875" (69.8 mm x 66.6

mm x 98.4 mm). It may not be used to power any other devices, other than the System 2. Refer to Figure 8.

CAUTION: This transformer has an internal fuse which cannot be repaired or replaced.

External Standby Battery

If AC power is lost, the System will operate normally by automatically switching to the standby lead-acid

battery. The System charges this battery at a voltage of 13.8 volts. Operating time under battery standby

conditions will vary depending upon system activity and the type of Card Readers or Keypads used.

Typical battery operation times are listed below and assume normal system activity and usage. These are only

estimates, other factors that will effect battery operation time depend on battery condition, number of LEDS ,

type of readers, programmed relay time etc.

To install the battery, locate the supplied wire harness. It consists of a nylon plug attached to a pair of six inch

red and black wires, each with a .187 inch spade terminal for connection to the battery. Observe polarity and

connect the RED to Positive (+) and the BLACK to Negative (-). Plug the nylon plug into socket H1 located

in the lower left hand corner of the circuit board. The battery may be connected after the AC power is

connected. Allow 24 hours for the battery to reach full charge. Refer to Figure 8.
