Perimeter System Wiring - Honeywell FF-SPS4 Series Installation Manual

Perimeter System Wiring

IMPROPER CONTROL SYSTEM
Ensure independent stop circuit relays have mechanically linked contacts that prevent contact
overlapping in the event of a welded contact.
Failure to comply with these instructions could result in death or serious injury.
The following figures illustrate the electrical wiring of the safety perimeter systems. The
customer is responsible for providing the safety relays, R, the restart push-button, the arc
suppressors, and the test circuit. The two NO safety contacts and the NC safety contact of the
FF-SPS4 are designed to switch at a minimum of 50 mA.
