Wireless Monitoring of HVAC Equipment
This transceiver is part of the Notifact network for wireless monitoring of HVAC equipment. It is designed to monitor the operation of single compressor rooftop or refrigeration units. At the Notifact web site, the user configures which individuals will receive a message regarding certain operating conditions and the delivery method. Delivery methods include pagers (alphanumeric, numeric), fax, e-mail, PCS or telephone (voice delivery).
The message sent out will contain the condition which generated the transmission, and also the make, model, and location of the equipment.
The transceiver is powered by the equipment power source and constantly monitors various inputs. When an input is out of range, the transceiver transmits the condition over the North American AMPS (advanced mobile phone system). The transmission is received at the Notifact messaging center and then relayed to the selected message recipients by the configured delivery method. Every 24 hours, the transceiver will also transmit to the Notifact message center information about itself and the unit it is monitoring. This transmission tells the Notifact center that the transceiver is properly functioning, powered, and able to transmit.
Information for the equipment monitored includes: Any conditions that are still pending, fan run time and number of cycles in the last 24 hours, and compressor run times and number of cycles in the last 24 hours.

Duct Air Quality Transmitter (AQS-D)
TRIATEK's AQS-D Series Duct Air Quality Transmitter is a high quality, solid state device that senses the level of contaminant gases in air ducts and accurately converts that level to a 0-10 VDC output signal. The AQS-D monitors the air quality so the HVAC control system can adjust the amount of fresh air required for comfort as well as health. Also, energy costs can be reduced by minimizing the amount of outdoor fresh air during periods of little or no occupancy. http://www.triatek.com/
