Typical Wiring Diagram
ZN-34UA
NOTES:
1. Normally open parallel connected gate
valve contacts, or the equivalent.
2. The maximum loop resistance for each
zone is 100 ohms.
3. Connect the supervisory contact
operated output of the zone (terminal 6
or 12) to the input of a dedicated
AE-30U (terminal 5 or 6). Multiple ZN-
34UA zones may be connected to a
single AE-30U. Refer to the
CP-35
Wiring Information,
P/N 315-085178,
for signal factor load units.
4. The ZN-34UA is a latching device and
follows ULC S527 requirements.
5. Minimum wire size:
18 AWG
Maximum wire size:
12 AWG
6. Positive and negative ground fault
impedance threshold
≤
40K ohms.
7. TB positions 1-12 are power limited.
