Product Overview • The model WIAR3, Wireless Repeater is a wireless device that operates by receiving a sensor’s coded signal and then transmitting that signal to a receiver, greatly increasing the effective range of the system. It will be necessary to install a Wireless Repeater if distance or interference is making it difficult for a wireless sensor to communicate with either a General Sensor’s Single Port or 4 Port Receiver. Under ideal conditions (no interference from steel machinery or cabinets and a clear line of sight between the receiver and its corresponding sensor), a Wireless Repeater can increase the effective range of the receiver to more than 700 feet. Please Note: For a typical installation, the presence of steel cabinets, machinery, electrical equipment, etc., will limit the effective range of the system, even when used in conjunction with a Wireless Repeater. 1.Do I need a Wireless Repeater? • Before you begin, make sure a Wireless Repeater is necessary to solve the communication problem between the receiver and the sensor(s). The fastest way to do this is to remove the sensor from the wall, bring it up close to its corresponding receiver, and push the sensor’s blue Test button at the bottom of the sensor’s printed circuit board. If the DIP switch settings on the sensor and receiver match, the receiver should scroll through its LED display, indicating a good communication link. • If the receiver does NOT scroll through its display, check the DIP switch settings on both units. If the settings are not the same you must change them so that they agree. Make sure you remove the battery before changing the DIP switch settings or the micro-computer in the units will not recognize the change. Once you change the settings, push the red Reset button on the receiver. Now bring the sensor up close to the receiver and push the blue Test button again to see if the receiver scrolls through its display. A Wireless Repeater will not solve the problem if the receiver still does not scroll through its LED display. If this happens call General Sensors’ technical support toll-free at 1-800-778-0836 for further assistance. • A Wireless Repeater is needed to boost the signal if the receiver scrolls through its LED display when the sensor is brought up close to it and tested, but does NOT scroll through its LED display when the sensor is tested after being mounted in its ultimate location. This usually means that something between the sensor and the receiver such as steel cabinets or machinery is blocking successful transmission of the signal. 2.Finding a location for the Wireless Repeater: • A Wireless Repeater reacts in the same way as the Single Port and 4 Port Receiver to interference from steel cabinets, machinery, etc. Simply installing a Wireless Repeater right next to the sensor or receiver you are having trouble with will probably not solve the problem, since the object(s) that are interfering with the signal sent by the sensor will also obstruct the transmission of a good signal by the Wireless Repeater. 2 • The ideal place to install the Wireless Repeater is high on the wall, about halfway between the sensor and receiver that are having trouble communicating. If possible, try and place the Wireless Repeater away from any steel cabinets, machinery, etc. If there are steel cabinets, machinery, etc. between the sensor and its corresponding receiver, try to place the Wireless Repeater against a wall where there is a direct line of sight between it and both the sensor and the receiver, as shown below: Receiver Sensor Wireless Repeater 3. Powering up the Wireless Repeater: • Before proceeding to mount the Wireless Repeater in its final location you should connect the unit to a 12VDC power source. General Sensors Inc. recommends using 22 AWG, stranded wire when making connections to a power source. • You can commonly obtain a 12VDC power source from centralized alarm boxes or building automation systems. In the event that power is not available from such a source, you can power the Wireless Repeater from a small 12VDC power module available from General Sensors Inc. or other suppliers that plugs into a 110VAC commercial outlet. Make sure the current rating of the power module is 200 mA or greater. The power outlet should be non- switched, meaning that light switches must not turn the sensor unit off. Another power option is to connect the repeater to a 4 Port Receiver’s 12VDC supply. The advantage to this arrangement is that the 4 Port Receiver provides standby battery power for the 12VDC supply. • To attach the 12VDC power source, locate the terminal port on the Wireless Repeater’s printed circuit board (see below). Using a small flat head screwdriver, press on the arm of the jack labeled “-“ and insert the negative lead into the jack. Do the same for the jack labeled “+” and insert the positive lead into the jack. 12VDC Terminal • When the Wireless Repeater has been connected to a 12VDC power source the Green LED labeled Power On will light. 4. Establishing a communication link: • Once you have found a good location and have connected the Wireless Repeater to a 12VDC power source, follow these three steps to make sure the Wireless Repeater is acting to solve the communication problem between the sensor and receiver: 1) Place the repeater in an upright position where you plan to mount it. If the repeater is receiving signals from a Wireless Sensor, the green LED labeled Receiving Transmission should be lit. 2) Walk over to the sensor with the communication problem an…

FCC ID: P72WIAR3 Response to TCB findings Hi Mike, We have identified the following issues after our review of the application: 1. This application is not activated in response to fire, security or safety of life issues and cannot claim the 15.231 (a) (4) exemption in order to operate continuously. It merely detects a condition which might result in water intrusion. Please examine the rules and submit a response to this issue. The device does not currently comply with the rules. The product software has been modified to operate during an alarm condition without the necessity of the 15.231(a)(4) exemption. The following transmission scheme has been verified through testing at Curtis-Straus: 1) At the initial detection of a fault, three alarm signals are sent. From the start of the first signal to the end of the third signal is 4.6s which satisfies the requirement that the transmission ends within 5sec. 2) 15min after the initial alarm, the sensor checks to determine if the fault condition still exits. If it does, another 4.6s alarm transmission is sent. If the fault no longer exists, no further transmissions are made. 3) Step 2 is repeated at 30min, 45min and 1hr after the initial alarm, but only of the fault condition is detected. If at any point the fault condition ceases, the sequence is halted and no further alarms are sent. Also, at the conclusion of the alarm transmission at the 1hr mark, no further transmissions will occur regardless of the fault condition. 4) At any point a manual reset can be implemented which will reset the sensor to step 1. 2. Please supply a discussion of the actual on-time of the transmitter. While the bit pattern has been somewhat related, it is unclear what the actual maximum on-time of the transmitter is in the worst case 100ms period. Plots of the actual transmitter pulse train should be presented to document compliance. Ans: Please see attached files: Bits.pdf and Transformat.pdf 3. Page 4 of the test report indicates that data was acquired at 10 meters, while the data table indicates 3 meters. Which is correct? Ans: All testing was done at 3 m. 4. For information. All emissions falling within the restricted bands of 15.205 must meet the general limits. Noted 5. Please supply a users manual. Ans: Please see attached file: instructions WIAR3.pdf 6. The form 731 indicates a request for confidentiality. However no formal letter justifying the request for confidentiality was supplied. This letter should also state what is to be classified as confidential. Ans: Please see attached letter-of-con.pdf 7. Please supply details of the antenna connector so compliance with 15.203 can be determined. Ans: Reverse Sex SMA Type 8. Please confirm a fresh battery was used during the testing.
