Alarm Resistor and Tamper Option
Place a maximum of five normally-closed contacts in series
with the 2.2 k-ohm EOL resistor. Each contact has either a
1.5 k-ohm or 2.2 k-ohm resistor across it. Refer to Figure 5.7.
Do not use contacts across the loop. The zone recognizes that
one or more of the contacts is opened, but not which ones or
how many.
