To wire external alarms
1. Get up to eight 24 AWG wire pairs of sufficient length to reach the far-end contacts
from the E7-2.
2. At the E7-2 end, strip approximately one inch (2.54 cm) of insulation from the alarm
wire ends.
3. Wire the E7-2 alarm inputs as follows:
a. Connect a pair of alarm wires to the first input position (AL1):
 Wrap the first wire (typically black) to the AL1+ pin.
 Wrap the second wire (typically white) to the AL1- pin.
b. Repeat Step 3a for each additional alarm input to use (AL2–AL7), as required.
4. Wire the E7-2 alarm output position (OUT) as follows:
 Wrap the first wire (typically black) to the OUT+ pin.
 Wrap the second wire (typically white) to the OUT- pin.
5. Route and dress the alarm wires out to the appropriate far-end interfaces and connect per
local practice.
