Hi,

I am struggling a bit with the follwowing and hope someone is in position to provide me support here:

I want to add two optical smoke detectors (DP721R Aritech - base DB702, 6 connectors) on a CD34 alarm central. The purpose is to link those detectors in serie and connect them on only one zone.

Could you tell me how I have to connect the alarm contacts on the base(s) and at alarm central side.

In advance many thanks for your support.

In series.

use two colours of your choice for the alarm outputs on the detectors, at the furthest use both colours at the next break into one colour and use that in both terminals but dont break the other.

Use the power to double up in second det and thru to last.

As for panel whats the other circuits doing, copy them.

Or do you want the technical version?

Scratch that, i was on a bout A2Z heads. If yours have diodes in them this wont work.
