Primary (AC) Power Circuit

A 16.5 VAC, 40 VA internally fused transformer (Radionics model D1640) is the primary power source for the D9112. The AC power circuit provides 1.9 Amps of rectified AC power. The panel reserves 500 mA of this power for internal operations leaving 1.4 Amps for powered devices.

Transient suppressors and spark gaps protect the circuit from power surges. This protection relies on the ground connection at terminal 10. Make sure you connect terminal 10 to a proper ground. See Connecting Earth Ground in the Installation section.

AC Power Failure

The D9112 indicates an AC power failure when the power at terminals 1 and 2 is missing. The AC Fail Time program item sets the number of seconds that AC must be missing before the panel acknowledges the failure and the number of seconds after the power returns before the panel acknowledges the restoral of power.

You can program AC Fail Time from 1 to 90 seconds. The Radionics default sets AC Fail Time at 10 seconds.

Installing the Transformer

Do not short the terminals of the transformer: Shorting the terminals opens the internal fuse causing permanent failure. Connect the transformer to terminals 1 and 2 of the panel before plugging it into the power source.

Use 18 AWG (minimum) wire to connect the transformer to the panel. Wire length should be kept as short as possible. Maximum length is 50 feet.

Connect the battery and then plug in the transformer: Radionics recommends that you always connect the battery first and then plug in the transformer. Instructions for Installing the Battery appear on the next page.

Only plug the transformer into an unswitched, 120 VAC, 60 Hz power outlet. Secure the transformer to the outlet with the screw provided.

Never share the transformer with other equipment: Foreign grounds on the AC input damage the D9112 power circuit.

AC wiring can induce both noise and low level voltage into adjacent wiring. Route phone and sensor loop wiring away from any AC conductors, including the transformer wire. Route data wiring away from AC and phone wiring.

D8004 Transformer Enclosure required for fire systems: Use the D8004 Transformer Enclosure for the D1640 transformer in fire and combined fire/burglary applications.
