FTC164 — Is there a maximum duration limit for DOUT activation triggered by Towing Detection?

Telematics Question
1

Hi,

I’m using an FTC164 on a motorcycle with a self-hosted Traccar server. I have a siren connected through an automotive relay driven by DOUT1, triggered by the Towing Detection scenario.

Current Output control settings: DOUT ON duration 5000 ms, DOUT OFF duration 1000 ms.

According to the DOUT controls wiki page, the ON/OFF cycle repeats “until scenario turns off”, and the Towing Detection description states the scenario only stops when ignition is switched ON. In my bench test this matches: the siren keeps cycling indefinitely and only stops when I apply ignition voltage.

My questions:

  1. Is there any parameter to limit the total DOUT activation time for a triggered scenario, so the output turns off automatically after X seconds/minutes even if the scenario is still active?
  2. I’ve seen “DOUT deactivation settings” with a Duration timeout documented for other devices (FMC650, FMM650) in the Call control context. Does the FTC164 have an equivalent general DOUT control section, and can it be applied to scenario-triggered outputs?
  3. If neither exists, is the recommended approach to handle this externally (e.g. a timer relay in the siren circuit)?

The device is wired to a switched auxiliary connector and runs on its internal battery while parked, so an indefinitely cycling output would drain the backup battery and keep the siren sounding with no way to stop it remotely.

Thanks.

Good Day,

Unfortunately, it is not possible to turn the DOUT off while the associated scenario remains active.

FMx devices provide DOUT ON time and DOUT OFF time settings; however, these control the output timing and do not act as an overall duration timeout. There is currently no configurable duration timeout for scenarios.

Thanks, and best regards,
