Notes

[1] The base panel standby and alarm currents consist of the main controller

board with no load other than the end-of-line resistors. In addition, the base
panel alarm current includes the IDC alarm current. Use these values for
base panel standby and alarm currents:

Control panel

Standby

Alarm

Three-zone

96 mA

180 mA

Five-zone

104 mA

224 mA

Ten-zone

128 mA

242 mA

[2] The maximum battery size that the panel can charge is 24 Ah (model 12V24A

or equivalent).

Battery space inside the control panel is limited. See Appendix D “Panel
specifications” on page 115 for more information.

[3] The IDC detector alarm current is included in the base panel alarm current.

For IDC detector standby current, enter the calculated total IDC standby
current from Form B or use these values:

Control panel

Total IDC standby current

Three-zone 9

Five-zone 15

Ten-zone 30

[4] Standby time value: 24 or 60 hours.

[5] Alarm time values:

5 min = 0.083 hr
10 min = 0.167 hr
15 min = 0.250 hr
30 min = 0.500 hr

[6] Total standby current may not exceed 635 mA.
