Rev. 5/03WIRELESS SASH SENSOR—1 OF 7 The Phoenix Controls Wireless Sash Sensor system detects a fume hood’s sash position through a radio signal that is transmit- ted to a wireless receiver. Sensors can be configured to operate with the sash configurations found on most VAV fume hoods. These sash sensors help maintain a constant average face velocity at the sash opening. SPECIFICATIONS Wireless Sash Sensor connected to horizontal magnet bar. Construction Tr a n s m i t t e r : • Fabricated in a corrosive resistent plastic enclosure capable of withstanding harsh fumes produced in a typical fume hood • Resistant to all chemicals that the cur- rent sash sensors are resistant to (which chemicals are the other sash sensors resistant to?) • Color: light gray Receiver: • Housed in a corrosive resistant plastic enclosure • Color: black Power Supply 3-volt Lithium coin cell battery; nominal capacity 70 mA-hours at a nominal load of 15K ohms. Operating Range Provides dual voltage input capability. The supply can operate from 24 VAC or 15 VDC input. • 24 VAC input: 18-30 VAC • 15 VDC input: 14.5-18 VDC Transmitter Frequency 433 MHz Dimensions • Transmitter: 2” W x 0.95” H x 0.25” D • Receiver: 5.895” W x 3.114” H x 1.805” D • Magnet bar: 1” W x 0.3” D.

Specifications subject to change without notice. Rev. 5/03 The WSS uses existing sash sensing technology, replacing the two-conductor wire that runs from the horizontal sash sensor to the horizontal/vertical (H/V) card with a low-power wireless radio frequency (RF) transmitter. The transmitter detects the change in sash position and trans- mits the signal to a receiver that is located no more than 20 feet away. The WSS receiver replaces the H/V card, which will be responsible for calculating the proportional signal that is sent to the fume hood monitor. Digitizing of the sash signal is accomplished by taking the current analog signal, passing it through an A/D con- verter, encoding it, and wirelessly transmitting to a receiver. The receiver then takes the transmitted signal, decodes it, converts it to an analog voltage, and amplifies it to a 0-10 VDC signal for the hood exhaust valve or the fume hood monitor. The receiver listens to multiple transmitters. Multiple transmitters can be in the same zone transmitting to mul- tiple receivers. For example, there could be two hoods, side-by-side, in a lab with hood 1 having two sashes and hood 2 having four sashes. Hood 1 will have one trans- mitter and hood 2 will have two transmitters; both hoods will have their own receivers. When hood 1 sash opens, the transmitter encodes the data and transmits the data to hood 1's receiver. Only receiver for hood 1 will process the data, hood 2's receiver should discard the data.

Rev. 5/03WIRELESS SASH SENSOR—3 OF 7 MOUNTING AND INSTALLATION Mounting and Orientation Transmitter The wireless transmitter shall be field mounted near the current sensor bar with a distance of no more than two inches from the actual senor bar. The transmitter shall have double sticky-back tape on one side for easy mounting. Receiver The receiver shall be field mounted somewhere above the hood or in a sensible location. The receiver mounting location shall not exceed a total distance of 20 feet from the farthest wireless transmitter. Installation Transmitter The wireless transmitter will be field mounted either underneath or above the current sash sensor bar. The sensor bar (two-conductor wire) will be field wired directly into the transmitter and the transmitter may not be more than two inches away from the sensor bar. The transmitter will also have a double sticky-back tape so that the unit may be affixed to the hood sash. Receiver The receiver will be field installed either above the hood or next to the fume hood monitor. In most cases, the receiver will be field mounted above the hood and no more than 20 feet away from the farthest transmitter. NOTE: Need to add drawings to this section. FIELD ADJUSTMENTS (CAILBRATION, CONFIGURATION, ETC.) The wireless transmitter is uniquely identified, so that the relationship between a transmitter and a receiver is one-to- one. The Phoenix factory address each wireless transmitter so that it communicates to specific receiver. The receiver is uniquely identified so the relationship between a receiver and a transmitter is one-to-many. Each receiver will be addressed via the front-end commissioning software. 4 OF 7—WIRELESS SASH SENSOR©2003 Phoenix Controls Corporation. Specifications subject to change without notice.

Nelson Date: 12 May 2003 Subject: How the sash transmitter module operates Description of Operation: It monitors the status of the sash opening through the use of a bar magnet and a series of magnetically actuated (reed style) switches. When the sash window is opened or closed, the position of the bar magnet relative to the reed switches changes, causing more (or less) switches to close. On detecting a change in the state of those switches, the system will automatically transmit a single message (that takes less than two seconds) containing its identity, and a code for how many switches have been activated. To ensure system integrity, it will also transmit a message indicating its status once every hour. CC: Techen:
