490X Engineer’s Reference Guide
Where Anti-Mask detectors are used, one of the following wiring
modes may be used.
ELF1 wiring is used for detectors that have a
relay output (a pair of terminals) for Fault or
Mask.
The installer should check what output type
the detectors are, noting that all the dectectors
should be of the same type with regards to the
Fault / Mask output.
Typical ELF1 Typical ELF2
ELF2 wiring is used for detectors that
have a transistor output (a single terminal)
for Fault or Mask.
Note: For ELF2 wiring format the 12K
resistor must be linked to the positive
side of the zone terminals.

Zone Doubling: Detector on Zone 1 will be Zone 1 and the
Doubled Zone will be Zone 9, Zone 2 will be Zone 2 and the Doubled
Zone will be Zone 10. E.g Zone number + 8 = Zone number for
Doubled Zone. The Zone triggered will be identified through the
resistor value by the system.
