GT490X Engineer’s Reference Guide
Three wiring options are available under 9 (EOL):
Norm: Standard GardTec wiring configuration without Mask or Fault detection.
Note: Does not give any Fault or Masking detection and should only be used with Zone pairing.
ELF1: ELF1 wiring is used for detectors that have a relay output (a pair of terminals)
for Fault or Mask..
ELF2: ELF2 wiring is used for detectors that have a transistor output (a single
terminal) for Fault or Mask.
Note: We would recommend that either ELF1 Format or ELF2 Format (dependant on detector output type,
Relay or Transistor) is used. ELF1 or ELF2 wiring modes will allow for Alarm, Tamper, Fault and Masking to be
monitored from a single zone without the need for zone pairing.
Note: The installer should check what output type the detector are, noting that all the detectors should be of the
same type with regards to the Fault / Mask output.

Zone Pairing.
A zone is used to monitor Masking and Fault.
This is achieved by selecting Zone Pairing as on. Zone Pairing cannot be used in ELF1 or ELF2
wiring modes.
When using Zone Pairing each zone will have a corresponding paired zone that will be used for
Masking and Fault signals. This is done by using the Odd numbered zones for the normal alarm
detection and the Even numbered zones for Masking and Fault Detection. For example.
Please note that half the zones on the system would be lost for processing the Mask and Fault
signals and it would be more prudent to use the ELF1 or ELF2 modes as described previously.
