NON-FAILSAFE: The relay coil is not energized in its non-active state. Loss of control power will cause the relay to
remain in the non-active state; i.e. a non-failsafe alarm or trip relay will not cause an alarm or trip on
loss of control power. Contact configuration is shown in FIGURE 2–3: Typical Wiring Diagram on
page 2–18 with relays programmed non-failsafe, control power not applied
FAILSAFE: The relay coil is energized in its non-active state. Loss of control power will cause the relay to go into its
active state; i.e. a failsafe alarm or trip relay will cause an alarm or trip on loss of control power. Contact
configuration is opposite to that shown in FIGURE 2–3: Typical Wiring Diagram on page 2–18 for relays
programmed as failsafe when control power is applied
