Installation keypads and other accessories in your security system. Their combined current consumption

(see Table 1) on each auxiliary output should not exceed 1A. The auxiliary supply is microprocessor-protected against current overload and automatically shuts down if the current exceeds 1.1A. Auxiliary power will resume once the overload condition has restored and within 1-60 seconds after performing the dynamic battery test (see below).

2.3.4 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 be on.

Key [1] also comes "on" 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.

2.3.5 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 16V

AC is present at the "AC" terminals. If AC is present, check the keypad wiring and verify 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.
