Use 18 AWG or larger for all low voltage power connections.
Note: Take care to keep power-limited circuits separate from non power-limited wiring (120VAC, Battery).
Unit should be tested at least once a year for the proper operation as follows:
Output Voltage Test: Under normal load conditions, the DC output voltage should be checked for proper
voltage level eFlow104NB: 24VDC nominal rated @ 10A max.
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage
(24VDC @ 26.4) both at battery terminal and at the board terminals marked [– BAT +] to ensure that there is no
break in the battery connection wires.
Note: Maximum charging current under discharges is 1.54A.
Note: Expected battery life is 5 years, however it is recommended changing batteries in 4 years or less if needed.

Terminal Identification:

Function/Description
Connect 120VAC 60Hz to these terminals: L to hot, N to neutral (non power-limited)
(Fig. 2a, pg. 5).
24VDC nominal @ 10A continuous output (power-limited output) (Fig. 2h, pg. 5).
Fire Alarm Interface trigger input from a short or FACP. Trigger inputs can be normally
open, normally closed from an FACP output circuit (power-limited input) (Fig. 2d, pg. 5).
FACP interface latching or non-latching (power-limited) (Fig. 2e, pg. 5).
Auxiliary Class 2 power-limited output rated @ 1A (unswitched) (Fig. 2f, pg. 5).
Indicates loss of AC power, e.g. connect to audible device or alarm panel.
Relay normally energized when AC power is present.
Contact rating 1A @ 30VDC (power-limited) (Fig. 2b, pg. 5).
Indicates low battery condition, e.g. connect to alarm panel. Relay normally energized
when DC power is present. Contact rating 1A @ 30VDC.
A removed battery is reported within 5 minutes.
Battery reconnection is reported within 1 minute (power-limited) (Fig. 2b, pg. 5).
Stand-by battery connections. Maximum charge current 1.54A (non power-limited)
(Fig. 2g, pg. 5).
