5. In Worksheet 5, enter devices connected to the Bell 2 Output. Calculate alarm currents, then add to get the
Bell 2 Output current subtotal.

6. In Worksheet 6, enter the total calculated subtotals of all listed outputs from Worksheets 1 through 5, then add to get
the combined current.

Total Current Load
(1.3A max. standby; 2.6A max.
alarm) (Can: 950mA max. standby;
2.25A max. alarm)
NOTE: The 5140DLM actually draws 55mA when active. However, since the control panel PCB current includes the main dialer
current, and since the main dialer is inactive when the 5140DLM is active, the 5140DLM imposes only a 15mA added load on the
current supply.
