Set Hold mode
Prevents false alarms when charging or cleaning the chambers.
While this mode is activated, pre-alarms will not signal and alarms will signal as pre-
alarms when faced with all effects (sound, relay activation and signalling).
To activate/deactivate this mode, press the
key for 3 seconds. The display will show the indicator.
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.
Maintenance mode
Disables gas pre-alarms and alarms for 1 hour for maintenance tasks.
While this mode is activated, no gas pre-alarm or alarm will sound.
To activate/deactivate this mode, press the
key for 6 seconds. The indicator will flash.
If there is a sudden increase in temperature near the transmitter, either in the cold room loading process,
or because the door has been accidentally left open, there is a risk of condensation occurring inside the
transmitter. In these conditions, the maintenance mode temporarily activates to avoid false alarms. The
transmitter returns to normal operation after 3 to 15 minutes.
In these cases, the maintenance mode cannot be manually deactivated.
The maintenance mode automatically activates for 5 minutes to prevent activation of alarms after
calibration has finished.
In this case, the maintenance mode cannot be manually deactivated.
Access code (Password)
Restricts access to the transmitter's functions to authorised personnel. Parameter b11 defines the code and
parameter b10 defines the function of the code:
b10 =0 Disabled
b10 =1 Blocks access to programming (Parameters) but enables the use of the rapid keypad functions
b10 =2 Blocks any keypad function
