GENERAL DESCRIPTION
The NOVA 71 is a supervised general purpose transmitter that can be
connected to magnetic contacts (door/window protection) or to
other sensors. It operates together with Rokonet’s programmable
receivers 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 preset
code 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.

OPERATIONAL MODES
NORMAL:
The NOVA 71 transmits an ALARM MESSAGE when it is triggered; when restored, it
transmits a RESTORAL MESSAGE. Only one ALARM MESSAGE is transmitted in any 2.5
minutes time slot.

Project number:13311 Page 3 of 5
Note: Extra restoral message can be generated by reopening and closing
the inputs.
WRITE: A Write message will be transmitted at power-up (and also by
pressing the tamper button for at least 3 seconds).
Note: The unit sends a supervisory message every 65 minutes indicating the
input 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 proper
operation.
[Fig. 1 : Opening the cover]
[Fig. 2 : Replacing battery]
LED INDICATION
After each detection, the LED turns ON momentarily.
On Low Battery condition – the LED will blink 3 times during each
transmission.
JUMPER SETTINGS
The Nova 71 has four jumpers:
• HOLD (J1)
OFF - 2.5 m Dead Time between alarm detections (restoral messages will be
sent immediately after the condition is detected).
ON - No Dead Time between alarm detections (the unit transmits after each
detection).
• RESPONSE TIME (J2):
FAST - 10 ms (for operation with shock sensor).
SLOW - 500 ms (for operation with magnetic contacts etc.).

• EXTERNAL SENSOR MODE (J3):
NC - Normally Closed.
NO - Normally Open.
• INTERNAL REED SWITCH (J4):
IN - Disabled.
OUT - Enabled.
INSTALLATION PROCEDURE
1. FRONT COVER REMOVAL (See Figure 1)
2. TRANSMITTER/RECEIVER COMMUNICATION SETUP
The NOVA 71 must identify itself to the system’s receiver by writing its
coded message into the receiver’s address memory. This is
accomplished by performing the following steps:
One. Set the receiver to Write Mode.
Two. Remove the insulation material from the battery. A Write message
will be sent during Power-Up. Verify that NOVA 71 has been
identified by the receiver.
Three. Set the receiver to Normal Mode.
Note: if for any reason it is necessary to re-send a write message, press
the tamper button for at least 3 seconds.
Step 3: SELECTION OF INSTALLATION LOCATION
One. Select a location best suited for communication quality and near the
intended wired detector (for switched sensor). Place the unit at the
highest possible position.
Two. Temporarily attach the unit to this point using two sided adhesive
tape.
Three. Generate an Alarm signal (by momentarily opening or closing the
input terminals) and verify that the receiver has received the signal.
If the alarm signal is not detected, reposition the NOVA 71 and try
again.
Note: For best results when using NOVA II, set the receiver in the
Communication Check Mode, and upon reception and verification,
return it to the Normal Mode.

Step 4: FINAL MOUNTING
One. Drill holes for mounting and wiring, using the mounting bracket as a
guideline.
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. Please
note: the mark on the magnet’s plastic case should be opposite the
mark on the transmitter’s case.

NOTE
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment on
and off, the user is encouraged to try to correct the interference by one or
more 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 from
that 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 the
party responsible for compliance (Rokonet Electronics Ltd.) could void the
user’s authority to operate the equipment.
