Emission Frequency Selection
IMPROPER PERIMETER DEVICE OPERATION
The emitter and receiver must be set to the same light emission frequency for proper operation.
Failure to comply with these instructions could result in death or serious injury.
The FF-SPS4 Series safety perimeter guarding system has internal switches that are used to
select the emission frequency (F1 or F2) of the infrared modulated light. To avoid crosstalk or
mutual interference when two perimeter guarding systems are close to each other, these
switches need to be set to different frequencies.
Remember, each emitter must be set to the same frequency as its corresponding receiver. If
a receiver receives a signal from two emitters of the same emission frequency, the receiver
remains in an alarm condition permanently. To return to a normal condition, the emission
frequency of the second emitter must be changed; then receiver power must be turned off and
on. All emitter and receiver devices are factory set to the emission frequency F1 or 50 kHz
(see figures 2-8 and 2-9).
