Det-Tronics PIRECL - Eagle Quantum Premier (EQP) Compatibility (Continued); EQP Network Address Duplication Warning; EQP Address Identification Chart; EQP LON Address Application Timing

H-4 95-8526
13.1
Do not assign duplicated addresses. Duplicated addresses are not automatically detected. Modules given the same
address will use the number given and report to the controller using that address. The status word will show the latest
update, which could be from any of the reporting modules using that address.
After setting address switches, record the address number and device type on the “Address Identification Chart” (form
95-8487). Post the chart in a convenient location near the Controller for future reference.
IMPORTANT
The PIRECL sets the LON address only when power is applied to the device. Therefore, it is important to set the
switches before applying power. If an address is ever changed, system power must be cycled before the new
address will take effect.
PIRECL Address Switches
Address switches for PIRECL are located within the device enclosure. Refer to Figure C-2 for switch location.
WARNING
Disassembly of the PIRECL housing and removal of the front electronics module from the bulkhead is required to
gain access to the network address switches. Power should be removed from the detector before disassembly.
If disassembly is performed in a hazardous areas, the area must be de-classied before starting disassembly.
WARNING
Disassembly of the PIRECL detector should only be performed with proper electrostatic discharge grounding
protection. A controlled lab or shop setting is recommended for device programming.
The PIRECL detector contains semiconductor devices that are sensitive to electrostatic discharge (ESD).
Damage caused by electrostatic discharge can be virtually eliminated if the equipment is handled only in a
static safeguarded work area and protective measures against static electricity discharge are employed during
the disassembly process. Since a static safeguarded work area is usually impractical in most eld installations,
handle the device by the housing, taking care not to touch electronic components or terminals. Use a wrist
grounding strap or similar method at all times to control accidental ESD when disassembling, programming, or
reassembling the PIRECL gas detector.
