SUPERVISORY OZONE MONITOR CZ12 PRODUCT SPECIFICATIONS

1) Supervisory Ozone Monitor comprising Sensor and Controller shall be provided to track continuously 24/7 concentration of ozone in air. The Monitor shall comprise sensor section and inbuilt controller section.

2) Sensor Section shall comprise Metal Oxide Sensor Element rated for continuous duty, and 3 1/4 inch monochrome LED Display Screen. The Screen shall display ozone concentration down to 2 PPB in increment of 1 PPB. Full range of display shall be 120 PPB. The LED Screen shall also display activation of relay contact, alarm condition, over range (above 120 PPB), and Fault Codes with Identification Number for each fault.

3) The system shall be equipped with Watch Dog Device to perform self diagnosis; upon start of Monitor, and continuously every 2 seconds. Self diagnosis shall be performed on every part and component of the system including sensor, calibration, ageing and drift of sensor, hardware and software, integrity of electronic circuitry, continuity and integrity of traces in the circuit boards, and perform functions of microprocessor. Self diagnosis shall also include verification of free and uninterrupted air flow through sample air circulating fan. Self diagnosis shall also include tests for software and flipping of binary digits generated by the microprocessor. Any fault detected shall be reported on the display panel with corresponding Fault Code Number. If any fault is detected in critical components, relay is activated to shut down the Ozone Generator and activate fresh air fan or other air quality correctional device.

4) The Monitor shall be factory set at 40 PPB to activate the relay and 50 PPB to activate audible alarm. Can be factory set to 80 PPB and 100 PPB respectively, if called for.

5) Monitor shall be provided with audible alarm to beep if any defect is detected and provide continuous sound to 85 dB if alarm condition is reached.

6) The Monitor shall be provided with unit mounted circulation fan to ensure continuous passage of sample room air. Watch Dog Device shall perform diagnosis every 2 seconds to ensure the fan is in operation and air passage is not restricted or blocked. If such condition is detected, it shall report with Fault Code Number on the LED Display.

7) The Monitor shall provide 0-10 VDC and 4-20 mA Analog Signal corresponding to Ozone Generator to BAS/BMS.

8 ) Relay Contact shall be provided with 1 NO and 1 NC potential free dry contact, rated for 250 VAC, 10 Amps (based on resistive current).

9) The Monitor shall be suitable for operation 24/7 in indoor or outdoor air.

10) Operating temperature of the Monitor shall be -22ºF (-30ºC) to +194ºF (+90ºC), 0 to 100 % RH (Non Condensing).

11) For failsafe and long time operation, sensor and display circuit boards shall be gold plated to 24 Carat 3 Micron thickness. This is to reduce or prevent loss of accuracy due to oxidation of the conductor surface over time. The populated boards shall be conformal coated to prevent damage from duct, moisture, condensation, traces of acid, and ozone.

12) All parts and components of the Monitor shall be lead free and comply to RoHS.

13) UL Listed and or approved Power Adaptor 100 to 240 VAC / 12 V for power supply to Monitor shall be factory provided.

14) All parts and components of the Monitor shall be housed in one neat, compact, 18 G CRS powder coated satin finish enclosure.

15) All parts and components used in the Monitor shall be UL Listed or UL Recognized. This requirement cannot be waived.

16) The Supervisory Ozone Monitor shall be Model CZ12, manufactured by Ruks Canada Ltd, Canada. Country of manufacture shall be Canada.
