SETTING NETWORK ADDRESSES
Overview of Network Addresses
Each PIRECL IR gas detector on the EQP LON must be assigned a unique address. Addresses 1 to 4 are reserved for
the EQP controller. Valid addresses for field devices including PIRECL gas detectors are from 5 to 250.
IMPORTANT
If the address is set to zero or an address above 250, the system will ignore the switch setting and the device.

housing. The address number is binary encoded with each switch having a specific binary value with switch 1 being
the LSB (Least Significant Bit). (See Figure C-1.) The device’s LON address is equal to the added value of all closed
rockerswitches.All“Open”switchesareignored.

1, 4 and 5 (binary values 1 + 8 + 16).
NOTE
For convenience in setting LON address switches, a “Rocker Switch Table” is included in the EQP System
manual (form 95-8533).
