Test the radio range.
A. Put all the detectors in test mode by pressing once on the Cfg1 button. The red LED lights up for 5 sec and then
flashes.
B. Press the test button on one of the detectors and the detector will test the radio range in permanent transmission
mode. The red LED on all the other detectors lights up steadily.
C. Position the detectors in their planned locations without fixing them in place.
• If the radio range is satisfactory, the red LED remains steadily lit.
• If the radio range is not satisfactory, the red LED flashes.
D. Move the detectors located outside of the radio range or programme one detector as a relay (see 2.5. Installing the
detector as a relay) then perform the test again.
E. To exit the test mode, press once on the Cfg1 button on all the detectors. The red LED goes out.
F. Perform the radio range test for all the detectors again to make sure they trigger, whatever the detector having
activated the alarm.

Fix the detectors in place following steps 1 to 4 in chapter 2.2. Installing a detector as a standalone device.
Specific cases
Adding a detector to an existing network
1. Put the detector to be added to the network in recognition programming mode by pressing 2 times on the Cfg1 key. The
red LED flashes.
2. Put one of detector that are already in the network in recognition programming mode by pressing 2 times on the Cfg1 key.
The red LED flashes.
3. Press the test key on a detector that is already in the network until the red LED on both detectors lights up steadily.
4. Briefly press Cfg1 on one of the detectors to exit the programming mode.
Putting a detector back into its factory configuration
Upon the back into factory configuration, the interconnection between the detectors will be deleted.
1. Press 2 times on the Cfg1 key.The red LED flashes.
2. Keep holding on the Cfg1 key until the red LED light up steadily. Release the button.
3. Briefly press Cfg1 to exit the programming mode.
2.5. Installing the detector as a relay
If the radio range between all the detectors is insufficient, one of the detectors can be progra-med as a relay. This means
that it will re-transmit alarms received to all the other detectors.
Examples:
A. If an alarm is activated on detector 1, only detector 2
and the control panel will be triggered.
Detector 1
Detector 2
It is possible to programme just one "relay" detector per network.
• To be programmed as a relay, the detector must first have been programmed for recognition by the network.
To programme a detector as a relay:
1. Press Cfg1. After 4 s, the red LED flashes. Keep holding the button down.
2. After 10 s, the flashing speeds up or slows down:
- if the flashing speeds up, the relay function has been activated,
- if the flashing slows down, the relay function is still deactivated.
3. Release the button and press briefly on Cfg1 to exit the programming mode.

B. Detector 2 is programmed as a relay. If an alarm is
activated on detector 1, the detector retransmits the
information on the whole installation.
