Switch Access Procedure
NOTE
It is strongly recommended to document all LS2000 gas detector network addresses as
well as the addresses of all other LON devices on the Address Identification Chart before
disassembling and programming the LS2000 gas detectors.
Removal of the retaining ring and the front electronics module of the LS2000 IR gas detector from
the bulkhead is required in order to gain access to the network address DIP switch.
1. Remove 24 Vdc power from the LS2000 detector.
2. Remove the retaining ring.
3. Carefully remove the electronics module by extracting it straight out from the bulkhead.
4. Set the network address switches.
5. Reinstall the electronics module by inserting it straight into the bulkhead, and then screw in
retaining ring.
NOTE
Take care to properly align the module’s electrical connector with the bulkhead connector
before attempting to fully insert the module. Failure to do so may result in damage to the module
and/or bulkhead.
6. Apply power after all network addresses have been programmed and all field enclosures are
properly installed.
TYPICAL APPLICATIONS
