Critical Environment Technologies Policy as it Pertains to Phasing out Manufactured Products and Field Service Support

PDC / DST Systems: These systems use the CAN digital protocol, which is somewhat proprietary, and as such, we have no replacement PDC systems available. The FCS/LPT-P or LPT-M are available as an alternative, sold as a complete system and can utilize the existing 4-conductor LAN wiring. These new products work on the Modbus protocol.

CETCI will support the replacement and field service of PDC and DST circuit boards and micros for as long as stock lasts or up until December 24, 2022. After this time, the end user will have to purchase the FCS/LPT-P as a complete replacement system package.

Enclosures for the PDC or DST are no longer available. The peripheral devices for the PDC system such as the Relay Module, Analog Output Module, etc. will no longer be supported because we have used up our circuit board inventory for these devices. If a new or replacement Remote Power Supply is required, the RPS-24VDC that works with the FCS system may be used with the PDC system.

PAC: We discontinued supporting the PAC over a year ago. This was a 4-channel controller which has been replaced by the QCC Quad Channel controller. All field service inquiries will be directed to purchase a new QCC controller.

GEM-MRI: This was a 1-channel Oxygen sampling system for hospital MRI rooms. CETCI will continue to provide replacement circuit boards and field service for the GEM-MRI for as long as stock lasts or up until December 24, 2022. This product has been replaced by the DCC-MRI.

SCS / MAC / GEM: These 1 and 2 channel self-contained systems have been replaced by the SCC or DCC self-contained systems. We will no longer be providing any replacement parts or field service for the SCS or MAC products. We will continue to provide replacement GEM circuit boards and field service for as long as stock lasts or up until December 24, 2022. There are no enclosures available for GEM products.

AST / ATW: These single channel analog transmitters have been replaced with our LPT or LPT-A model series. CETCI will no longer be providing replacement parts or field service for the AST or ATW analog transmitters.

AST-1000 / AST-X: We discontinued supporting these explosion-proof analog transmitters over a year ago and replaced the series with the CXT explosion-proof transmitter series that is available in both analog and Modbus digital configurations.

AST-IRT: This infrared refrigerant analog transmitter has been replaced with the ART infrared refrigerant transmitter. The ART is available with either analog or Modbus digital output. We will no longer be providing replacement parts or field service for the AST-IRT products.
 
BST: These BACnet digital transmitters have been replaced with the LPT-B digital BACnet transmitter. We will no longer be providing replacement parts or field service for the BST products.

PET: These BACnet digital transmitters have been replaced with the LPT-B BACnet transmitter. CETCI will continue to provide replacement circuit boards and field service for the PET for as long as stock lasts or up until December 24, 2022.
 
Accessories: We have newer models of remote alarms (strobe/siren units), etc. that will be used for field service replacement of older models that are damaged or have stopped working.

Sensors: Sensors remain relatively unchanged and readily available. There are a couple of electrochemical CO sensors that are no longer available but we have secured a replacement for at least one of them. In the case of solid-state sensors for CO we strongly urge users to update to electrochemical sensors for better accuracy and reliability, and to be able to meet new workplace exposure guidelines.

Any other requests we receive for field service replacement of parts not listed above will be dealt with on a case by case basis. However, because we have new models available for virtually everything we have built in the past, all field service inquiries will be directed to purchase the new devices.
