Perimeter Protection
IMPROPER INSTALLATION OF FF-SPS4 SERIES PERIMETER DEVICE
• Install FF-SPS4 perimeter devices in accordance with this installation manual and applicable
safety regulations and standards (OSHA, ANSI, European standards).
• Only allow entry into protected area by interruption of sensing field or other safeguarding
device.
Failure to comply with these instructions could result in death or serious injury.
IMPROPER PERIMETER PROTECTION
• Design control circuit to allow a manual restart before further machine operation can occur.
• Locate manual restart outside of danger zone where operator has a clear view of zone.
• Operator should NOT be able to reach manual restart from within danger zone.
• Design control circuit to prevent Programmable Logic Controller from overriding manual
restart.
• Install two FF-SPS4 perimeter devices (two beam minimum) per safety application.
Failure to comply with these instructions could result in death or serious injury.
Honeywell's FF-SPS4 Series device is a self-contained, perimeter protection device designed
to detect the body of an operator before gaining access to a dangerous area (see figure 1-3).
This device is a single thru-scan type that uses an invisible modulated infrared beam. The
interruption of the beam results in the opening of the output contacts and the generation of a
stop signal. The stop signal causes additional circuitry to arrest machine motion. Continued
operation of the machinery is prevented until the sensing beam is cleared. Misalignment or
dirt accumulation is indicated by a flashing indicator to allow timely preventive maintenance.
