FCC ID:JE4WT71Date: June, 1999Project number:13311 Page 2 of 5GENERAL DESCRIPTIONThe NOVA 71 is a supervised general purpose transmitter that can beconnected to magnetic contacts (door/window protection) or toother sensors. It operates together with Rokonet’s programmablereceivers and is powered by a standard 3-volt lithium battery.NOVA 71 FEATURES• Operates up to 1000 FT. (300m) range (outdoor)• Uses one of more than 16 million pseudo-randomly selected presetcode addresses for setup (no DIP switches).• Microprocessor design.• Extended battery life.• Fully supervised.• Selective response time:- Fast – for shock sensors- Slow – for magnetic switches, etc.• Selective input – N.C. or N.O.[Fig. 3 PCB drawing ]OPERATIONAL MODESNORMAL:The NOVA 71 transmits an ALARM MESSAGE when it is triggered; when restored, ittransmits a RESTORAL MESSAGE. Only one ALARM MESSAGE is transmitted in any 2.5minutes time slot.
FCC ID:JE4WT71Date: June, 1999Project number:13311 Page 3 of 5Note: Extra restoral message can be generated by reopening and closingthe inputs.WRITE: A Write message will be transmitted at power-up (and also bypressing the tamper button for at least 3 seconds).Note: The unit sends a supervisory message every 65 minutes indicating theinput state and battery condition.BATTERY INSTALLATION & REPLACEMENT 1. Remove the plastic cover. (See Figure 1) 2. Replace battery. (See Figure 2) 3. Close cover. 4. Perform a Communication Check with the receiver to verify properoperation. [Fig. 1 : Opening the cover] [Fig. 2 : Replacing battery]LED INDICATIONAfter each detection, the LED turns ON momentarily.On Low Battery condition – the LED will blink 3 times during eachtransmission.JUMPER SETTINGSThe Nova 71 has four jumpers: • HOLD (J1)OFF - 2.5 m Dead Time between alarm detections (restoral messages will besent immediately after the condition is detected).ON - No Dead Time between alarm detections (the unit transmits after eachdetection). • RESPONSE TIME (J2):FAST - 10 ms (for operation with shock sensor).SLOW - 500 ms (for operation with magnetic contacts etc.).
FCC ID:JE4WT71Date: June, 1999Project number:13311 Page 4 of 5 • EXTERNAL SENSOR MODE (J3):NC - Normally Closed.NO - Normally Open. • INTERNAL REED SWITCH (J4):IN - Disabled.OUT - Enabled.INSTALLATION PROCEDURE1. FRONT COVER REMOVAL (See Figure 1)2. TRANSMITTER/RECEIVER COMMUNICATION SETUPThe NOVA 71 must identify itself to the system’s receiver by writing itscoded message into the receiver’s address memory. This isaccomplished by performing the following steps:One. Set the receiver to Write Mode.Two. Remove the insulation material from the battery. A Write messagewill be sent during Power-Up. Verify that NOVA 71 has beenidentified by the receiver.Three. Set the receiver to Normal Mode.Note: if for any reason it is necessary to re-send a write message, pressthe tamper button for at least 3 seconds.Step 3: SELECTION OF INSTALLATION LOCATIONOne. Select a location best suited for communication quality and near theintended wired detector (for switched sensor). Place the unit at thehighest possible position.Two. Temporarily attach the unit to this point using two sided adhesivetape.Three. Generate an Alarm signal (by momentarily opening or closing theinput terminals) and verify that the receiver has received the signal.If the alarm signal is not detected, reposition the NOVA 71 and tryagain.Note: For best results when using NOVA II, set the receiver in theCommunication Check Mode, and upon reception and verification,return it to the Normal Mode.
FCC ID:JE4WT71Date: June, 1999Project number:13311 Page 5 of 5Step 4: FINAL MOUNTINGOne. Drill holes for mounting and wiring, using the mounting bracket as aguideline.Two. Mount the transmitter in place.Three. If relevant, connect the sensor to the input terminals.Four. Replace the front cover.Five. If the optional door/window magnet is used, mount it in place. Pleasenote: the mark on the magnet’s plastic case should be opposite themark on the transmitter’s case. [Rokonet Warranty] [Rokonet Subsidiaries]NOTEThis equipment has been tested and found to comply with the limits for aClass B digital device, pursuant to part 15 of the FCC Rules. These limits aredesigned to provide reasonable protection against harmful interference in aresidential installation. This equipment generates, uses and can radiate radiofrequency energy and, if not installed and used in accordance with theinstructions, cause harmful interference to radio communications. However,there is no guarantee that interference will not occur in a particularinstallation. If this equipment does cause harmful interference to radio ortelevision reception, which can be determined by turning the equipment onand off, the user is encouraged to try to correct the interference by one ormore of the following measures: • Reorient or relocate the receiving antenna • Increase the separation between the equipment and the receiver • Connect the equipment into an outlet on a circuit different fromthat to which the receiver is connected • Consult the dealer or an experienced radio/TV technician for help.Changes or modifications to this equipment not expressly approved by theparty responsible for compliance (Rokonet Electronics Ltd.) could void theuser’s authority to operate the equipment.
