The question is wiring connection not base installation
Expert:  Pete replied 1 year ago.
Hi,
If you look closely at the base diagram, you will see the wiring information.
Customer: replied 1 year ago.
my question is 0v-+v is required for base connection or not ,because this is AUX- out put 0-28v commining from panel for out put divices So without this connection to every detector base can we use direct to the output divice?
LSN a1/a2 , b1,b2 is IN and OUT loop this is o.k
Expert:  Pete replied 1 year ago.
Hi,
Yes, the 0v-+v connections are required.
Are you setting this up for the first time?
Customer: replied 1 year ago.
this product is first time for me.what is the use of this voltage line in the detector ? Normally Loop in and loop out also carrying voltage to drive detector.
yes in the sounders other than loop in and loop out - required 0-28 v line to drive which is feeding from panel and remote indicators and displays required this Aux- voltage as i think.
Please make sure that " am i right or not.? --- because i waiting to start connections.
thanks and regards.
