To use the optional Phone Line Trouble Relay, install a
D136 Relay in socket K5. The D136 has a Form “C” dry
contact, rated at 2 A maximum current at 30 VDC
(power from independent supply). The relay activates
(reverse state) when a faulted condition appears on either
the primary or alternate telephone lines, or when a
communication failure occurs.

12 VAC Mode
Connect a 12 VAC, 20 VA transformer to Terminals 1
and 2 using 18 AWG (1.2 mm) stranded wire, maximum
length 50 ft (15.3 m). Commercial fire applications
require the D8004 Transformer Enclosure for the D1220
Transformer or the D2071AmC Kit.

The hardwire transformer mounted in the
D4103R Enclosure, included in the
D2071AC Kit, replaces the D1220
