DEI 2102T Power on Quirk

What I have found with the DEI2102T is that when first powered on, it automatically comes on in the 'disarmed' state.

I'm using the White/Black Starter disable (which is ground when armed) with a pull-up resistor as enable/disable trigger for another circuit;
This is all well and good if you power it up, then arm it - it will subsequently disarm and re-arm properly with that starter-disable output changing state accordingly.
But MAJOR issue is that it powers up in the DIS-armed state (even when the remote fob is not present)
So to bypass it, you simply have to disconnect and reconnect the battery
i.e. if it's powered and armed, disconnect the battery, reconnect and you have successfully bypassed it.

Anyone think of a way whereby it can be wired to overcome that initial power-up condition?

Is the battery being disconnected and reconnected on a regular basis or is it just that easy to disconnect the battery on the vehicle? If either apply, I would use a backup battery.

BTW, what year, make, and model is the vehicle? Are you using any interfaces with the 2102T?

~wirewise~ Verify all wiring with your meter before making any connections!

Thank you for your reply.
It's a motorcycle application - no other interfaces, just using the module as a remote trigger for an enable trigger for a custom application.
It's simple enough on initial install just to set it to armed and then it is fine from there.
And from there on, battery disconnection would be relatively infrequent and can easily apply the re-initiation of initial arming after disconnected for maintenance activities etc as necessary.
It's nothing to do with the inconvenience factor as it would be quite infrequent requirement from user perspective.
It's the security factor of someone being able to over-ride an armed condition by disconnecting & reconnecting the power that is the concern.

Battery back-up would be intriguing - simple solution, diode protected so current cannot flow out to the main system, nor current into it when main battery connected - need to see what I can find that is super-small; good news is doesn't have to supply any significant current, just maintain state.
Maybe something like A23 or A27 (would like something smaller though - any ideas?)

I'm also looking at an electronic solution that will ensure it manipulates the power-on state to give a disable condition at power-on, but still respond to arm/disarm signals from there forward.

I tried a battery test - the thing just consumes too much current for a battery to be practical; depletes is just a few hours.

I did complete an electronic design however, that ignores the turn-on state of not-armed until it receives it gets its first armed pulse.
