1 SA823 U-NET REPEATER The SA823 is a signal repeater to extend the range of U-Net two-way wireless technology. It is fully compatible with any U-Net enabled sensors and controller. The signal repeater is designed to be installed by a system installer in cases where signal reception is poor or extended range is required for the home. The repeater does not alter the existing binding network between gateway and devices, in fact devices do not need to be physically removed from their mounting location when adding the repeater. This allows the installer to service the user in the shortest time possible without disrupting to the home interior. It comes with installer friendly feature such test mode to indicate signal strength using LED display and audible beeps for areas not in line of sight such as corners. Powered by backup battery, this allows the repeater to be easily placed anywhere while searching for its optimum location. There is the also a Beacon mode which allows the installer to conveniently walk around the home to observe signal strengths from the gateway when deciding on the best location. Product Overview Front View View with Battery Cover removedRepeater network overview The role of the Repeater in a U-Net network can be summarized in the diagram below. Level : Repeaters are distinguished into Level-1 and Level-2 as set by their Level jumper setting. Each pair of Level-1 and 2 repeaters define a unique signal path to the gateway. Signals from each pair will not cross over to another pair. - Level-1: Repeater closest to the gateway. In most cases adding a Level-1 Repeater is sufficient to cover a wide range. A gateway can have more than one Level-1 Repeaters to branch out at different angles from the gateway. - Level-2: Repeater to extend signal from Level-1 Repeater. Only one Level-2 repeater can be added for each Level-1 Repeater. To create the link between the pairs, repeaters must perform U-net binding with each other. Repeaters with the same level cannot bind with each other. Lastly, like all end devices under the gateway’s network, each repeater must perform U-net binding with the gateway. This ensures the gateway is aware of the repeater’s own condition such as low battery, tamper, etc. Note: It is advisable to use as few Repeaters as possible in a network in order to reduce signal hops between device and Gateway. Like any wireless network, more signal hops not only mean longer delay in transmission but also adds higher risk of signal interference resulting in lost messages as more devices are added. This degrades the overall network quality. Join: The repeater becomes associated with an end device through ‘Joining’. This is a loose form of binding that tells a repeater which devices it should repeat signals for and which do not. Joining is a manual process similar to U-net binding except there is no need to remove end devices from their mounting position to activate a learn key. Simply trigger the end device for it to transmit its ID which is then picked up by the repeater. Joining does not disrupt the original U-net binding between end devices with gateway. Inversely, a device is disassociated from the Repeater through ‘Un-join’. Removing a device from the Repeater’s memory helps to reduce unnecessary transmission of RF signal which will improve overall quality of the network. LED Table The table below describes the LED indication at various stages of the unit’s operation. Pairing stage: During the Repeater’s pairing activity, Status LED along with the buzzer beeps indicate the status of the paring. Status Status LED Buzzer BeepFactory reset state.

Remove the wall bracket by pushing it downwards and then remove the battery cover. 2. Prepare three AA 1.5V batteries. Do not insert them into the unit yet. 3. Ensure the Level jumper in the Repeater is set to Level-1. 4. Set a U-net compatible gateway into binding mode. Usually this is achieved by pressing the Link button on the gateway. 5. Insert the batteries with correct polarity at this point. Within a few seconds a long beep sound will be heard indicating the pairing is complete. 6. Time-out will occur if the binding process was unsuccessful, indicated by 3 short beeps. If this happens, refer to the Manual Binding procedure in the Troubleshooting section. Note: A Repeater must reset back to factory default before it can pair with another gateway. See the Factory Reset section in the Troubleshooting section. Adding a Device (Join process) 1. Put repeater into Joining mode by pressing the learn button until 3 beeps is over and release. Repeater will enter learning mode for 30 secs. 2. Bring the repeater in close range to the device, around ~10cm. 3. Simply trigger the device (PIR trigger, door sensor open, etc.) to emit a signal which will be picked up by the Repeater. Note: - Unlike binding, there is no need to press learn key on device. - Refer to the LED Table for details of pairing indicators. 4. Once the signal is picked up by the Repeater, it will emit one long beep sound. Joining process is complete. From now on Repeater will start routing signal for this device. 5. Time-out will occur if the Joining process is unsuccessful, indicated by 3 short beeps. Note: PIR motion sensors will have a retrigger interval or sleep period which lasts longer than the Repeater’s 30 secs Join period. If time out occurs, try again when the PIR is ready. If necessary, cover the PIR with a dark cloth when preparing the Repeater. 6. Repeat the steps above for other devices. Note : - Each Repeater supports a maximum of 8 devices. - Keypad and Siren devices are NOT supported by this Repeater. - Remote keyfobs do not need to Join to any Repeater. All Repeaters will retransmit signals from Remote Keyfobs in the same network. - A Repeater will Join only devices from the same gateway paired to the Repeater - A device can Join to only one Repeater at any one time. If the device needs to Join to another Repeater, it must first Un-Join from the first Repeater. The Un-Join procedure is similar to Join procedure except two beeps will be heard when completed. - If any device is deleted by the gateway, the gateway will inform the Repeater to Un-Join this device from its memory. Testing There are two signal test methods provided by the Repeater; - Test Mode : this tests the signal between the end device to Repeater - Beacon Mode : this tests the signal between the Repeater to Gateway. It is also used to test signal between Repeaters. Good Normal WeakRF LED Flash Green 3 times Flash Orange 2 times Flash Red 1 time Beep sound* 3 long beeps 2 long beeps 1 long beep Test Mode This is used when searching for a good spot to mount the Repeater. In this mode the unit will indicate signal strength for each signal sent by the device. 1. Join a device to the Repeater as described above. 2. Set the Mode switch to Test mode. 3. Place the Repeater at a distance away from the end device. 4. Trigger the device, e.g. open a door sensor or press the on/off button on a smart plug. The Repeater will indicate the received signal strength as follows: Good Normal WeakRF LED Flash Green 3 times Flash Orange 2 times Flash Red 1 timeBeep sound 3 short beeps 2 short beeps 1 short beep 5. Set the Mode switch back to Normal mode to exit. Beacon Mode In this mode the Repeater transmits a ping signal to the gateway at every 5 secs interval. The reply signal from the gateway is then measured for strength and indicated by RF LED and buzzer beeps. This feature allows the installer to walk around the premises while observing the signal quality at the spot. This is useful for; - identifying weak areas for placing a sensor - testing signal strength between Repeater and Gateway before mounting it permanently - testing the signal strength between Repeater pairs when adding a second Repeater. To use Beacon mode with a Gateway; 1. Set the Mode switch to Test mode.
3 2. Press the Tamper switch on the Repeater. The ping signal will be sent every 5 secs. The Repeater will indicate the received signal strength as follows: *same as Test Mode but long beeps instead of short beeps 3. Set the Mode switch back to Normal mode to exit. A matrix summary of the Test Mode and Beacon Mode can found in Appendix A. Mounting the Repeater A clean smooth surface is required to securely mount the Repeater. The unit should be placed on the wall, at least 1.5m high from floor, for improved reception. 1. Use the wall bracket as a template to mark and drill the position of 3 mounting holes on the wall. 2. Fix the wall bracket to the wall using the plastic wall plugs and fixing screws provided. 3. Connect the DC adaptor to DC jack of the unit and place the battery cover over the battery compartment. Note : the unit should always be powered DC adaptor instead of its backup battery. 4. Slide the unit down into its wall bracket ensuring the tamper switch is pressed by the wall bracket as shown below. Tamper Protection Tamper protection is activated when the tamper switch is pressed continuously for more than 2 minutes. Removing the unit from its wall bracket will release the tamper switch and generate a full alarm condition. Maintenance 1. The unit reports its presence to the gateway every 60 minutes. This way the gateway will be alerted if the Repeater becomes missing. 2. Low Battery: When its backup battery becomes low, the unit will report back to the gateway and the Status LED will flash every 30secs. Replace the battery the soonest possible to keep the unit operating during a power cut. Level-2 Repeater Connecting a Level-2 Repeater This follows the same procedure as binding to a Gateway. 1. Firstly, bind the second Repeater to the Gateway as in the section Binding with Gateway. 2. Once completed, setting its Level jumper to Level-2. 3. Set the unit into pairing mode by press and holding its Learn button for 3 secs until a long beep sound is heard, then release the button. The unit is now ready to pair for 30 secs. 4. Within 30 secs, set Level-1 Repeater into pairing mode also by performing the previous step above. 5. Soon both units will emit a long beep indicating both are now connected to each other. Refer to the LED Table for details of pairing indicators. Disconnecting a Level-2 Repeater 1. Set the Level-1 Repeater into pairing mode by press and holding its Learn button for 3 secs until a long beep is heard, then release the button. 2. Within 30 secs, bring the Level-2 Repeater in close range to Level-1 Repeater, around ~10cm and press the Tamper switch on the Level-2 Repeater. 3. 2 long beeps will be heard on Level-1 Repeater indicating both are now disconnected from each other. Note: - Level-2 will still preserve all the Join devices in its memory. It will continue to serve these devices even after connecting to a new Repeater or directly to Gateway. Only by doing a Factory reset will all the Join devices be erased from the Repeater’s memory. - Level 3 jumper is for factory use only. Troubleshooting The troubleshooting table lists some possible causes and solutions Symptom Cause of Failure Recommendation Binding with Gateway does not work. The Repeater has previously been paired with another gatewayPerform factory reset on the Repeater. Remote keyfob cannot Join to Repeater. Remote keyfob does not require Join procedure None. All the Repeaters in the network will transmit signals from remote keyfob Keypad and Siren cannot Join to Repeater. Keypad and Siren are not supported. Keep keypad or siren within range of the GatewayRepeater keeps beeping whenever a signal is received. Repeater set to Test Mode Switch Mode jumper to Normal Mode. Repeater is added but still cannot achieve desired range. 1. Range is too far. 2. Signal is blocked by thick wall. 1. Set the Repeater to Level-2 and add a Level-1 Repeater in between to extend range. 2. Place Repeater near openings in the wall such as a door or window. Cannot pair a second Repeater to first Repeater Both Repeaters are set to the same Level Set one of them to a different Level using the Level jumper. Manual Binding 1. Set the unit into pairing mode by pressing and holding its Learn button for 3 secs until a long beep sound is heard, then release the button. The unit is now ready to pair for 30 secs. 2. Set a U-net compatible gateway into binding mode. Usually this is achieved by pressing the Link button on the gateway. 3. Within 5 secs the unit will emit a long beep indicating the binding procedure is complete. Refer to the LED Table for details of pairing indicators.
4 Reset To Factory Default To reset the unit back to factory default state: 1. Press and hold the Learn button for 3 secs until a long beep sound is heard, then release the button. 2. Within 30 secs, press and hold the Learn button again but this time for more than 6 secs until another long beep sound is heard. This indicates the reset is complete. The LED will blink every 2 secs indicating no paired ID code is stored its memory.
