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 mA
Five-zone 15 mA
Ten-zone 30 mA
[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.
