HELPFUL HINTS /// n The Xanboo ™ Repeater is suitable for indoor use only. FAQ’S /// HOW FAR AWAY CAN THE REPEATER BE PLACED FROM THE CONTROLLER? Typically 60 feet. CAN I PLACE THE REPEATER IN A DIFFERENT ROOM FROM THE CONTROLLER? Yes, the Repeater uses radio frequencies to communicate with the Controller. These frequencies can travel through objects such as walls, ceilings, and floors. HOW MANY SENSORS CAN I USE WITH MY CONTROLLER? The Controller can support up to 20 sensors. TECHNICAL SPECS /// n Attaches to vertical flat surfaces (antenna must point up) n Test/Discover button Typical Range Outdoors: 250 feet Typical Range Indoors: 60 feet Frequency Range: 418 MHz PRODUCT DESCRIPTION /// The Xanboo ™ Repeater “repeats” signals coming from any wireless Xanboo ™ device and “re-transmits” that signal, effectively doubling the range of any of your Xanboo ™ devices. PACKAGE CONTENTS /// n (1) Repeater n (1) 9V Power Adapter n (1) Wall Mounting Kit INSTALLATION /// The Xanboo ™ Repeater should be mounted indoors, at a height of 6-8 feet. It should be placed to facilitate other devices’ communication with the Controller. If one of your Xanboo ™ devices is having difficulty communicating with the Controller, mount the Repeater in between the two. If communication is restored, that is a good place for the Repeater. NOTE: You can only have one Repeater in between the device and the Controller. Though you can have more than one Repeater per system, repeaters will not communicate with each other, so you need to make sure that a device can make contact with the Controller using only one Repeater. Below is an example of a multi-repeater installation. 1. Peel the paper strip from the double-sided tape located on the back of the Repeater. You can also mount the Repeater more securely using the screws in the wall mounting kit. Affix the screws leaving 1/16” space between the screw head and the object. 2. Mount the Repeater onto the screws and slide down to lock into place. 2I REPEATER WALL MOUNTING KIT 9V POWER ADAPTER SENSOR THERE CAN ONLY BE ONE REPEATER IN BETWEEN THE DEVICE AND THE CONTROLLER REPEATER 1SENSORREPEATER 2CONTROLLER/PC TROUBLE SHOOTING /// PROBLEM Controller does not recognize the Device during discovery Events are not triggered Device does not respond when used SOLUTION 1. Position the Device in closer proximity to the Controller and try again. 2. Ensure there are no other wireless devices interfering with the Motorola Device, which transmits on the 418MHz frequency. 3. If you determine that the Device is simply too far away from the Controller, then you have the option of purchasing a Motorola Repeater to effectively double the range of the Device. 1. Has the Device been registered properly with your Gateway? 2. Ensure that you have the proper settings configured for the new Device. 1. Ensure the new Device has been registered properly with the Controller by viewing the status of the Device on your PC Software. 2. Place the Device in another location closer to the Controller. 3. Press the ‘Test’ button on the Device to confirm that it is working. 4. If you determine that the Device is too far from the Controller, you can add a Repeater to the system to effectively double the range of the Device.

Information regarding the tethering process. The repeater learns which sensors are in the system by monitoring the sensor registration process or by monitoring successful friendly exchanges between base and sensor. If the repeater is introduced to a system where a sensor is already out of range of the base, then that sensor will need to be moved into range for the repeater to accept it. The users manual has omitted this information in error. 2. How are acknowledge packet handled? The repeater forwards the acknowledge packet back to the remote sensor. The acknowledge packet is delayed by the watchdog timer circuit so that the 10 second silent period is observed. 3. How many remote sensors can a repeater service? Four. 4. How does the repeater handle closely spaced multiple messages? The watchdog timer forces a 10 second space between forwarded message transmissions. 5. What is the decision process for transmitting? If a sensor which is already considered part of the system (see 1 above) is not acknowledged by the base, then the repeater will forward the message by making its own message to the base. One of the header bits is flipped to tag the message as a repeated message.

BE THERE /// EVEN WHEN YOU’RE NOT 115 W 30TH ST. NEW YORK, NY 10001 P: 212.714.2295 /// F: 212.714.2491 /// www.xanboo.com To: Professional Testing Inc: Attn: Mike Royer Date: May 9, 2005 Subject: Technical Questions regarding XRT-750 1. How does the device know which remote devices it is associated with? The repeater has a considerable amount of processing power and memory. The repeater monitors the "Discovery Process" and there is a propriety learning program that allows it to learn the other security sensors in the Xanboo system. The repeater transmits a 19.5 millisecond Discovery packet when first installed. It does not transmit a System Integrity packet. In normal operation the repeater could run for months without transmitting a single packet. 2. How does the device know which base station it is associated with? Each Xanboo device is registered at close range with the base station via the discovery process. i.e. the discovery button is pressed only when the Base station is in discovery mode. The device ID appears on a screen and user accepts it. The repeater is not a sensor, it does not exchange system integrity packets with the base station. 3. What specifically is the repeater looking for to make a decision to retransmit? The repeater monitors the System Integrity or alarm packet from the Sensor. When it hears a sensor transmit, but does not hear a base station AcK signal, it repeats the sensor signal, which has been stored in memory. During the wait for the AcK signal it checks a table in it's internal memory to see if the device is a house hold registered device. Only house hold registered sensors that were not received by the base station are retransmitted. Thus the XRT-750 is functioning as a Diversity Receiver.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 May 6, 2005 RE: Xanboo/Core Technologies FCC ID: OU4-XRT750 After a review of the submitted information, I have a few comments on the above referenced Application. 1) Please provide information regarding the tethering and registration process mentioned in the new updated operational description. The device does not appear to be programmable from the users manual provided so it is uncertain how this device knows exactly what packets it can retransmit (and also reject) and what controller it is associated with. Therefore, how does the repeater know what device(s) it is associated with and which controller it is associated with? 2) If the repeater is forwarding packets onto the controller, Please explain how acknowledge packets make there way back to the sensor original sensor if the repeater is only forwarding messages in one direction only. It is assumed that if transmissions can not reach in one direction, then they would also not be able to return back as well. 3) It is also still unclear if the device is capable of forwarding information from more than one sensor, or if a repeater is only tied to one specific sensor per repeater. 4) If the repeater received 2 messages in < 1 second, does it retransmit both messages or one message? Does it transmit them as a group or space them apart. Please explain? 5) What does the device decode to ensure something is part of its system? If another system was nearby operating on the same frequency, how does this device reject it? What specifically is it looking for before it acknowledges something is valid for retransmit?

Exhibit H Description of Operation Xanboo/Core Technologies XRT750 Product Description Using store and forward the repeater is used to extend the range of certain sensors. To accomplish this, each packet received is demodulated, decoded, and processed to determine if action is required. The repeater sends a “keep alive” packet every 15 minutes for system integrity purposes. The maximum system packet length is from the Home and Away module, which has a length of 23.3 mS. The minimum period between transmissions is 10 seconds. Apart from the above “keep alive” function, the following conditions are required for the repeater to transmit. 1. The repeater only repeats the signal of the device that it has been tethered to, not any device or any Xanboo system device. 2. The repeater only repeats if the main controller fails to acknowledge the tethered device’s original transmission. 3. The repeater will not repeat Xanboo packets intended for controllers other than the controller that it is registered to. 4. Repeaters will not function in cascade style. Two or more repeaters cannot be used in series to extend the system range. 5. A ten second watchdog timer prevents transmissions less than 10 seconds apart.
