6.6.4
Connection to the FACP line
Each of the following examples illustrates the control via reset input according to Sec. 6.6.3.2. If connection with the control via
the voltage supply is required, the control circuit in the figures below can be implemented as described in Sec. 6.6.3.1.
6.6.4.1
Connection to zone detection via
Al
/
St
relays
For connection to zone detection lines, the control relay is
usually actuated from the line plus. The precondition is that
the line plus also switches for “Zone ON/OFF” and “Reset”.
Fig. 36 Connection to zone detection
6.6.4.2
Connection to selective identification or addressable loop via
Al
/
St
relays
With line technologies such as selective identification lines
and addressable loops, the control relay is actuated from a
software-controlled output (output card or control module).
The output is programmed via the FACP software using the
“Zone Off” and “Reset” functions.
A normal relay or PMR 81 semi-conductor relay can be used
as the control relay.

dressable loop
