SENSOR SECTION

8. The Sensor Section shall comprise independent Sensors to track each IAQ parameter, TVOC, Residual Ozone, CO2, CO, Temperature, and RH. Each Sensor shall be independently programmable. Units for display such as PPM, PPB, ΕF or ΕC shall be user selectable.
9. It shall be provided with 256 MB RAM, Micro Processor, Flash Memory, Real Time, and Lithium Battery back up.
10. Each Sensor shall deliver analog output signal approximately linearly proportional to the readings in the range 0-10 V, 0 – 5 V, 4-20mA (specify at time of order). These may be interfaceable to BAS/BMS.
11. Shall have 5 numbers of Normally Open (NO) Dry Contacts, field assignable by user to any sensor, or multiple number of Dry Contacts may be assigned to one Sensor (example: Activation and Alarm may be assigned to the same Sensor). The Dry Contact shall be rated for 3 Amps on 24 V AC/DC. It shall be possible to program at field activation level for any IAQ parameter either on rising or dropping values.
12. Peripheral connectors shall be unit mounted and comprise one each of USB 2.0, RS 232 and Ethernet download.
13. Side panels of the Sensor Board shall be provided with factory installed female plug for connecting power adaptor, On Off switch, USB 2.0 and RS 232 connectors, selector switch for change over between space and duct mount, fan for sampling room air, and exhaust vent to discharge sampled room air.
14. Sensor Section shall be provided with spigots for connecting pitot tubes, if duct mount option is used. It shall be possible to field connect factory provided pitot tubes without opening the Monitor.
15. Power supply shall be 12 V AC/DC 3 Amp. Adaptor 100 to 240 V / 12 V shall be factory provided.
16. The Monitor shall be factory provided with Lithium battery to power Real Time Clock and for data storage.
17. For fail safe and long time operation, printed circuit boards shall be immersed in 24 carat gold
3 Micron thick. This is to reduce or prevent loss of accuracy due to oxidation of the conductor surface over time. The populated board shall be conformal coated to prevent damage from dust, moisture, condensation, traces of acid, and ozone.
18. All parts and components of the Monitor shall be lead free and shall comply to ROHS
(Restriction in use of Hazardous Substances).

20. Monitor shall be programmable at site by user through touch screen membrane.
Programming Levels shall include System Set Up, Defining Upper and Lower Ranges, Alarm Levels, Bar or Line Graph, Alarm Reports, Time History and Real Time Reports with user specified time periods, defining levels for activation of NO Dry Contacts and Alarm levels, and defining if activation and alarm is on ascending or descending values. Real Time and Time History records shall be displayed in graphic or tabular format as chosen by user.
21. If set Alarm level is reached, color of display of the parameter concerned shall change from Green to Red.
22. If set Activation and or Alarm levels is reached, icons indicative of these shall appear at the bottom of the respective parameter.
23. The Display Section shall be factory integrated onto the Monitor Section to form one neat compact unit Model CZ8-PD.
24. The Monitor shall be CE Certified.
25. Total Air Quality Monitor shall be CZ8-PD, manufactured by Ruks Engineering Ltd, Canada. Country of manufacture shall be Canada.

CZ8-AD

26 Display shall be 4 Line x 20 Character, back lit monochrome LCD. Programming shall be by membrane touch pad keys. Each IAQ parameter shall scroll on the screen one after another. By pressing the prompted touch pad key, chosen parameter shall remain hold steady till user commands it to scroll again.
27. User programmable features shall be same as described in Clause 20 under PD, except Real Time and Time History and graphic features are not available.
28. If set Activation and or Alarm levels is reached, icons indicative of these shall appear at the bottom of the respective parameter.
