Re: EOLR Depate

["petem" <petem001@xxxxxxxxx>]

we use jelly filled bi-connector... I use those for any wire that can be in
contact with humidity..(and here in Quebec that's all perimeter device)

I use them for access reader connection too.. never had false alarm on those
type of connection..

I always strip the wire to the cooper and do a pretty tight joint between
the 2 conductor before squeezing the bi-connector...I don't trust the small
teeth in there to do the connection
