Table 2-2.

A Each alarm connection is labeled identicall
y—this means each
connection can be an
‘Alarm in’ or ‘Alarm reference’ signal, provided the second alarm connection
provides the other alarm signal.
Step 2 Measure two strands of twisted-pair wire (18-to-20 AWG) long enough to connect to the external alarm
device.
Step 3 Use a wire stripper to remove the casing from both ends of each wire to 0.25 inch (6.3 mm) ± 0.02 inch
(0.5 mm). Do not strip more than 0.27 inch (6.8 mm) of insulation from the wires. Stripping more than
the recommended amount of wire can leave exposed wire from the alarm connector after installation.
Step 4 Insert the exposed wires for the external alarm device into the power and alarm connector connections
as shown in Figure 2-21.
