Location and Mounting

Remove the PCB, mounting hardware and keypad from the packaging inside the panel box. The circuit board should not be mounted into the back of the cabinet until all cables are pulled into the cabinet and prepared for connection. Before mounting the cabinet, push the four (728 Ultra) or five (738 Ultra) white nylon-mounting studs into the back of the cabinet. Select an installation site that is not easily accessible to intruders. Leave at least 5cm (2in) around the panel box to permit adequate ventilation and heat dissipation. The installation site should be dry and close to an AC source, ground connection and telephone line connection.

Earth Ground

Connect the zone and dialer ground terminals from the control panel to the metallic enclosure and cold water pipe or grounding rod as per local electrical codes.

For maximum lightning protection, use separate earth grounds for the zone and dialer grounds as shown in

Figure 1. For UL installations, the metallic enclosure must be grounded to the cold water pipe or grounding rod.

AC Power

2.3.1

AC Power

Do not use any switch-controlled outlets to power the transformer. Use a 16.5Vac (50-60Hz) transformer with a minimum 20VA (40VA recommended) rating to provide sufficient AC power. UL/cUL listed systems require a Universal

Model No. UB1640W plug-in transformer. Connect the transformer as shown in Figure 2.The power supply can provide a maximum of 1.1A for battery charge current.

Do not connect the transformer or the backup battery until all the wiring is completed.

Backup Battery

We recommend connecting a backup battery to power the control panel in case of power loss. UL/cUL installations require the use of a backup battery. Use a 12Vdc 4Ah/7Ah rechargeable acid/lead or gel cell battery. For UL/cUL

installations use only a 7Ah battery. Connect the backup battery after applying the AC power as shown in Figure 3 on page 3. When installing the battery, verify proper polarity, as reversed connections will blow the battery fuse. Connect

the red battery lead to the positive battery terminal, and the black battery lead to the negative battery terminal of the control panel.
