AC Power-Up
To turn on AC power, perform the following steps:
1.
Plug the 1321/1321CN into a 24-hour, unswitched 120VAC outlet.
Following power-up, one of the following is displayed on the keypad: AC, dI (disabled);
BUSY STANDBY (on alpha keypads); or NOT READY (on fixed-word keypads). The
green POWER LED (or READY LED on some keypads) should light.
2.
After approximately 1 minute, the initial displays revert to DISARMED...READY TO
ARM for alpha keypads, or READY for fixed-word keypads (if there are no faulted
zones). This 1-minute delay allows PIRs, etc. to stabilize.
To bypass this delay, press: # + 0.
NOTE: If you do not get the “READY” displays described above, refer to “Trouble
Conditions” in the SYSTEM OPERATION section.
Calculating the Battery Size Needed
Determine the total device current draw after filling in the AUXILIARY DEVICE CURRENT
DRAW WORKSHEET that follows. To this figure add the 100mA that is drawn by the control
panel itself. Then, to determine the battery size needed, use the following formula:
Total Current Drawn* x Number of hours standby wanted = Battery Ampere/Hours.
* Convert mA figure to decimal Amps (see example that follows).
Example: If total auxiliary device current drain is 450mA, add 100mA for the control panel,
for a total of 550mA (0.55 amps); if 24-hour standby is wanted, the calculation is:
0.55A x 24 hours = 13.2 Ampere/Hour battery needed
In this example, two 7 Amp/Hr batteries (connected in parallel) must be used.

TOTAL =
Current available from Aux. terminals = 600mA max (500mA max for UL installations)**
* If you are using hardwire devices such as PIRs, refer to the specifications for that particular unit's
current draw.
** In UL installations, maximum current draw from the Auxiliary Output and the Alarm Output
combined
must not exceed 600mA.
