Detector initialisation
Each time that the detector is supplied with power, an initialisation process begins, during which the
the alarms, digital inputs and keyboard are disabled.
After a few moments, the detector begins to operate normally. However, at least 5 minutes should elapse for optimal operation to be reached.
AUTO-CONFIGURATION function
Allows for digital input polarity to be configured and for the audible alarm to be enabled / disabled.
1.- Ensure that both digital inputs are in standby (not activated)
2.- Disconnect the power supply, connect it again and press the 'AUTO-CONFIGURATION' push-button 5 consecutive times before 2 minu-
tes have elapsed. The
and
indicators light up alternately.
3.- Press the
key to enable / disable the mute key.
4.- Keep the "AUTO-CONFIGURATION" push-button pressed down for 5 seconds to save the configuration of the digital inputs.
Optionally, we can return the detector to its factory settings. To do so, press the "AUTO-CONFIGURATION" push-button 5 times
before step 4.

vation and signalling).
To activate/deactivate this mode, press the
key for 3 seconds. The display will show the
You may also activate/deactivate this function remotely using digital input 2 (DI2) if required.
This mode will remain active for a maximum of 5 hours, then will deactivate automatically.
If this mode is activated using the
key, it can only be deactivated using the same key. This is also true when activating the mode using
digital input 2.

Alarm relay is activated.
Operation check (Bump test)
EN-378 and F-GAS international standards require verification of the correct operation of the transmitter at least once per year.
Please check what current local regulations specify for such cases. Always ensure that you comply with current local
regulations.
We recommend using AKO-58110 cable. To carry out this check, follow the instructions included in the kit.
