eDLT Bell Press Mod

Is there a way to reverse the operation of the Bell Press on the eDLT's
so rather than when you press it energises a relay, it de-energises a relay.

We have a door lock that needs to be energised to lock.

 

Hi Carl,

A few options,

1. you can use the L5504RVFC changeover relays. With that wired correctly it can energise the circuit when the relay is off and de-energise when the relay is on so bell press will work normally

2. A SPDT relay or contactor run off a normal RVF style relay can also provide the same 'reverse' service but is more advanced to wire up. Bell Press still works normally for this config.

3. Use a 'Timer' on the eDLT button and have it set the group address of lock relay to level 1% (as it doesn't seem to go to 0%) for 2-3 seconds etc, then final level as back to 'ON', but you would need to initially set the group address to 'ON' using a 'Lock' button / logic somewhere. You also need to set the relay channel 'Turn on Threshold' to something above 1%, like 3%.

probably a few more ways too. eg rotary scenes with the 2 levels OFF/ON with logic follower,

Good Luck,

Brad
