DETECTORS
The heart of the Argus fire detection is the spark detector. The detector is equipped with
a lens that can see infrared light emitted by extremely small sparks and warn you before
they have a chance to become a fire.
As of 2014 only the 535 detector is available for sale, and all orders for Argus will
include the 535 detector only. Although there are a few changes between the two
detectors, they operate identically. This means that if you choose to replace one of the
old 343 detectors in your gin with a new 535 one, the zone you modified will still work
as before.
The changes between the 343 and 535 detectors that you should be aware of are:
• Mounting dimensions are different. When replacing old detectors, new holes must be
drilled for the mounting brackets.
• The 535 detector has a two-tone LED that indicates whether detector is in an alarm
state (red) or standby (green).
• The End-of-line (EOL) module required for the 343 detector is no longer needed for
the 535. Instead, there is a switch on the 535's circuit board that should be toggled in
the last detector in a zone. For more information about zone card/detector wiring,
please refer to section 2.4.
