JA-80Z Radio signal repeater 1 / 2 MKG51302
JA-80Z Radio signal repeater
The JA-80Z signal repeater is a device belonging to Jablotron’s OASiS
system. It has been designed to extend the range of remote devices whose
signal is not strong enough to communicate with the control panel or whose
communication is unreliable. The repeater function lies in the transmission
of a signal received from an enrolled device with a little delay. The delay
ensures that a possible conflict between the repeater transmission and the
transmitting device is avoided. Each device enrolled to the repeater must
also be enrolled to the control panel.
Repeater architecture
•The repeater has 40 addresses for devices and one address for an
OASiS control panel.
•It copies the state of the PGX, PGY, IW and EW outputs of an
OASiS control panel and repeats them for wireless sirens and AC/
UC modules.
•The addresses are filled by sequential enrollment. The enrolled
devices can only be deleted by resetting the repeater.
•Uses an LED and beeper (if connected – just for installing and
testing purposes) to indicate the strength of the signal received from
enrolled devices.
•Compatible with all OASiS detectors and remote controls with the
exception of the JA-84P.
•It does not support transmissions for JA-8xF keypads, JA-80A sirens
and other JA-80Z repeaters.
•Enables a hard-wired detector connection to the INP terminal.
Power supply and input description
Only a person with corresponding electro-technical
qualification can connect the power supply.
The power supply is double-insulated (safety class 2)
and does not incorporate a protective grounding wire.
•A double-insulated power cable should be used with a minimum cross-
sectional area of 0.75 to 1.5 mm2. The power cable should be connected to a
switched mains supply fused to 10 Amps.
•In the repeater, connect the cable to the power terminals equipped with a
fuse of type T200 mA / 250 V.
•Fix the cable firmly to the cable holder in the repeater making sure that the
wire ends are properly secured and connected in the terminals.
If there is a power supply failure, a LowBatt message is sent from the
JA-80Z after a 30 minute delay. This may be disabled by setting DIP3
switch to the OFF position.
A double-balanced INP input with a fixed natural reaction (delayed loop) is
available for the connection of one hard-wire detector. Activation of this
input is transmitted to the control panel as a signal from a device to which
the repeater has been enrolled in the control panel. The reaction of this
loop can be configured in the control panel.
The repeater front cover is protected with a built-in tamper sensor and the
box must be protected against being torn off the wall with a tamper contact
delivered with the package (see below).
Repeater enrollment mode
1. Switch the DIP4 switch to the “ON” position before you connect the
power supply.
2. Open enrollment mode on the control panel and scroll to the required
position for the repeater.
3. While the rechargeable battery is still disconnected, connect the power
input of the repeater, thus sending the enrollment code and enrolling
the device to the control panel. The control panel subsequently enrolls
itself to the repeater automatically.
4. You can exit the control panel’s enrollment mode by pressing the „#“
key.
5. It is also possible to enroll other devices to the repeater by the insertion
of batteries.
•Correct enrollment of a device is always signaled by a one-second
flash of the green LED and optionally, a long beep.
•Exceeding the maximum amount of devices (full memory) is
indicated by several quick short flashes of the green LED and
optionally, four short beeps. The device is not enrolled.
6. You can exit the repeater’s enrolment mode by switching off the DIP4
switch.
Adding devices to the repeater (additional enrollment
mode)
•Switch the DIP4 switch to the “ON” position.
•The devices are enrolled by the insertion of batteries
•Correct enrollment of a device is always signaled by a one-second
flash of the green LED and optionally, a long beep.
•Exceeding the maximum amount of devices (full memory) is
indicated by several quick short flashes of the green LED and
optionally, four short beeps. The device is not enrolled.
•You can exit the enrollment mode by switching off the DIP4 switch.
Device signal indication
The number of flashes of the green LED on the control panel motherboard
indicates the strength of the signal received from the given device upon its
activation as follows:
1x 25% (1/4) signal strength
2x 50% (2/4) signal strength
3x 75% (3/4) signal strength
4x 100% (4/4) signal strength
If the beeper is connected is the signal strength indicated by one to four
beeps as well.
Remove the beeper for normal operation see fig. 1 (9).

Rear box tamper sensor installation
The rear tamper sensor (against the box being torn off the wall) works on
the basis of a magnetic contact (supplied with the package). The contact
must be installed during installation of the box.
1. Break off the prepared rectangular opening at the bottom of the box
opposite the circuit board terminal.
2. The remains of the broken-off plastic molding must be removed using a
sharp tool (knife).
3. Put the box onto the selected surface and mark the fixing holes and the
position of the prepared opening.
4. Attach the permanent contact magnet onto the marked surface, see fig.
1 (7).
5. Install and fix the box (the magnet goes through the rectangular box
opening).
6. Stick the magnetic sensor (the second part with the conductors
brought-out) to an interior side of the box (maximum separation from
the magnet should be 2 cm), see fig. 1 (8).
7. Connect the outputs to the TMP and COM terminals on the
motherboard without a balance resistor.
8. Switch DIP2 to the ON position, see fig. 1 (5).

DIP switch description
The input on the INP terminal is monitored in the “ON” position
The rear tamper sensor is monitored in the “ON” position
The LowBatt is sent after 30 minutes AC failure in the “ON” pos.
The enrollment mode is active in the “ON” position
Device reset
Resetting the whole device is irreversible and causes the deletion of the
enrolled control panel and all enrolled devices from the repeater.
1. Switch off the 230V power output and disconnect the backup battery.
2. Connect the RESET jumper and leave it connected.
3. Connect the supply voltage and the battery.
4. Disconnect the RESET jumper.
