224DA/DB, 724DA/DB Four Channel (w/failsafe output)

Features
& Benefits
•
FAULT indicator and DETECT indicator for each channel.
• TS 2 type output on "DB" models.
• Advanced digital microprocessor design.
• Each loop is sequentially scanned to minimize crosstalk
and reduce power consumption.
• Front panel capability for selection of four loop
frequencies, eight sensitivity levels, and two operating modes (pulse
or presence).
• Four solid state outputs.
• Programming of the detector is accomplished by DIP switches
for sensitivity, frequency, and mode selections.
• Two front panel light emitting diodes (LED) provided for
each channel.
• Each loop circuit is continuously monitored to detect intermittents
and other faults.
• The Winky-Blink™ loop monitor remembers and indicates
intermittent and failed loops.
• Meets all applicable NEMA specs and the California/New York
20 Joules lightning test.
