In Section 2, you made temporary power connections for the purpose of ~
programming and testing the keypads. This section provides information
about final power-up procedures and battery size calculations.
Earth Ground Connections
The designated earth ground terminal (25) must be terminated in a good
earth ground for the lightning transient protective devices in this product to
be effective. It also must be grounded to enable the telephone line fault
indicator to work properly. The following are examples of good earth grounds
available at most installations:
Metal Cold Water Pipe: Use a non-corrosive metal strap (copper is
recommended) firmly secured to the pipe to which the ground lead is
electrically connected and secured.
AC Power Outlet Ground Available from 3-prong, 120VAC, power outlets
only. To test the integrity of the ground terminal, use a three-wire circuit
tester with neon lamp indicators, such as the UL-Listed Ideal Model 61–035,
or equivalent, available at most electrical supply stores.
AC power-up
1. Plug the 1321/TF2 or 4300 transformer into a 24-hour, uninterrupted
120VAC outlet.
2. Following power-up, AC, dl (disabled), or Busy-Standby (Alpha keypads)
or NOT READY (fixed-word keypads) will be displayed. Also the green
“POWER’ LED* on the keypad(s) should light.
* Somekeypadsare equippedwitha “READY’ LEDin placeof a “POWER LED.
After approximately 1 minute, the initial displays will revert to
DISARMED...READY TO ARM for Alpha keypads, or READY for Fixed-
word keypads (if there are no faulted zones). This l-minute delay allows
PIRs, etc. to stabilize.

To bypass this delay, press: [#l + [01.
Connecting The Back-Up Bettery
In the event of an AC power loss, the Control panel is supported by a back-up,
rechargeable gel cell batte~. The minimum battery size recommended is the
No. 467 (12V, 4AH) battery. See “Calculating The Battery Size Needed”
below. The battery is installed in the control cabinet.
‘ The standby battery is automatically tested every 4 hours, beginning 4 hours
after exiting programming mode. In addition, entry into the test mode will
cause a battery test to be initiated.
Calculating the Battery Size Needed
Determine the total device current draw after filling in the AUXILIARY
DEVICE CURRENT DRAW WORKSHEET on the next page. To this figure
add the 100 mA that is drawn by the control panel itself. Then, to determine
the battery size needed, use the following formula
TotalCurrentDrawn*x Numberofhoursstandbywanted= BatteryAmpere/Hours.
* ConvertmAfiguretodecimalAmps(seeexample).
Example: If total auxiliary device current drawn is 450 mA, add 100 mA for
the control panel, for a total of 550 mA (0.55 amps); if 24-hour standby is
wanted, the calculation will be:
0.55 ti x 24 hours = 13.2 &npere/Hour battery needed.
In this example, two 7 Arnp/Hr batteries (comected in parallel) must be used.
