Figure 4: Sample Power Requirement Calculations
If in the above example you were to add an LCD Keypad (110mA) to the 30m (100ft), you would not exceed the wire’s limit. But adding the
LCD Keypad to the 305m (1,000ft) wire or 91m (300ft) wire would exceed the wire’s limits, thereby causing devices to function at decreased
capacity.
Figure 5: External Power Supply Connections
Do not use the same transformer for the control panel and the external power supplies. Modules should never be installed
more than 914m (3,000 ft) from the control panel.

Power required by devices connected to control panel’s auxiliary
output must not exceed the auxiliary output’s limit:
(A) + (B) + (C) + (D) + (E) + (F) + (G) + = 455mA<700mA = OK
15m (50ft.)

Magellan Module (MG-RCV3)
(A) = 35mA

7.5m(25ft.)

Motion Detector Module
(DGP2-70)
(E) = 30mA
LED Keypad (DGP2-648)
(F) = 110 mA
LED Keypad (DGP2-648)
(G) = 110 mA
As indicated in Table 2, this run of wire can support 454mA. Total
mA on this run of wire:
(D)110mA + (E)30mA + (F)110mA + (G)110mA = 360mA<454mA
= OK
255m(950ft.)
APR3-ZX8
(B) = 30mA
As indicated in Table 2, this run of wire can
support 700mA. Total mA on this run of wire:
(A)35mA + (B)30mA = 65mA<700mA = OK
Motion Detector Module
(DGP2-60)
(C) = 30mA
305m(1000ft.)
As indicated in Table 2, this run of wire can
support 136mA. Total mA on this run of wire:
(A)35mA + (C)30mA = 60mA<136mA = OK
91m(300ft.)
30m(100ft.)
Milliamps required by devices connected to a power supply do not draw power from the control panel’s auxiliary output.
152m(500ft) from control panel
152m(500ft) from control panel’s AUX. output
Therefore this run = max. 273mA
609m(2000ft) from control panel
152m(500ft) from power supply
Therefore this run = max. 273mA
