Remote 4 wire Smoke hookup

[murlyns]

Can you tell me how do I hook up a 4-Wire Smoke Detector when I am using a ELK- M1XIN (M1 16 Zone input Expander) that is located in a remote building and thus unable to power the smoke off the +SAUX and NEG out put on the main M1 board.

Thanks

You could power the smoke detector from the same place that you power the XIN from. The obvious drawback is the loss of reset that the Elk does on SAUX bus. For more info, search CT for SAUX.

You could add a relay expander with a relay to the remote building to do the reset based on a rule and a function key. Is the smoke going to have a built in sounder? If so, that adds another reason for the relay expander. Of course, make sure your install meets local codes, etc yada yada yada...
