Auxiliary Power Terminals

The AUX + and AUX - terminals on the control panel can provide a maximum of 450mA (728 Ultra) or 500mA (738 Ultra)

12Vdc (200mA 12Vdc for 24Hr stand-by on UL/cUL installations). You can use the auxiliary power supply to power the motion detectors, keypads and other accessories in your security system. Their combined current consumption should

not exceed 650mA (728 Ultra) or 700mA (738 Ultra). See Table 1 for current consumption levels. The auxiliary supply

is microprocessor-protected against current overload and automatically shuts down if the current exceeds 650mA (728

Ultra) or 700mA (738 Ultra). Auxiliary power will resume once the overload condition is restored and within 1 to 60 seconds of performing the dynamic battery test.

Battery Test

The control panel conducts a dynamic battery test under load every 60 seconds. If the battery is disconnected, or its capacity is too low, the [1] key in the trouble display mode will illuminate. Key [1] will also illuminate if the battery voltage drops to 10.5 volts or less when the control panel is running on the back-up battery (no AC). At 8.5 volts, the panel shuts down and all outputs close.

Keypad Function Test

We recommend conducting a power-up test on keypads installed far from the control panel. To do so, temporarily connect the keypads near the control panel and connect the transformer. After 10 seconds, begin entering random commands on the keypad and verify that the keypad beeps in response to these commands. Then open a zone to ensure that the keypad and the control panel are responding to these signals. If the keypad does not respond and indicator lights do not illuminate, verify that approximately 16Vac is present at the AC terminals. If AC is present, check the keypad wiring and verify that there isn't a short between the black and red keypad wires. If the keypad does not respond, please contact your local Paradox Distributor.

Telephone Line Connection

Connect the incoming telephone company wires into the TIP and RING connections of the control panel. Then run the wires from

T 1 and R 1 to the telephone system as shown in Figure 4.

If the STATUS LED is always ON, the panel is using the phone line.
