6.4. Alarm indication (LED)
A red LED located in the head of communication flashes in case of confirmed alarm status.
• Flashing 1 Hz: Level 1
•
Flashing 3 Hz: Level 2
If the alarm memorization is activated, the LED continues to flash until the alarm is
acknowledged with the TLU or until the detector is powered off, then powered on again.
If the alarm memorization is disabled, the LED stops flashing when the alarm fades.
If the device is used in a safety loop in a potentially explosive area (EN60079-29-1),
the upper alarm must be memorized, and a manual action must be taken to clear
it.
6.5. Wireless communication tool TLU600
All settings and tests of detectors can be done by the wireless communication tool TLU600.
This communication tool and its software are compatible with all Oldham Simtronics
detectors: MultiFlame, MultiTox and MultiXplo. Communication is made via infrared link
(IrDA), similar but more efficient than infrared links for computers. IrDA head should not be
placed facing the sun as it significantly reduces the communication with the TLU600.
Please refer to the wireless communication tool operating manual for more details.
