Kidde i12010S - Manual (Page 12)

• For alarms that are used as single station, DO NOT CONNECT
THE RED WIRE TO ANYTHING. Leave the red wire insulating
cap in place to make certain that the red wire cannot contact
any metal parts or the electrical box.
• When alarms are interconnected, all interconnected units must
be powered from a single circuit.
• A maximum of 24 Kidde Safety devices may be interconnected
in a multiple station arrangement. The interconnect system
should not exceed the NFPA interconnect limit of 12 smoke
alarms and/or 18 alarms total (smoke, CO, Smoke/ CO
Combination, heat, etc.). With 18 alarms interconnected, it is
still possible to interconnect up to a total of 6 remote signaling
devices and /or relay modules (see page 15 for details on
interconnecting Kidde devices).
• The maximum wire run distance between the first and last unit
in an interconnected system is 1000 feet.
• Figure 3 illustrates interconnection wiring. Improper
connection will result in damage to the alarm, failure to
operate, or a shock hazard.
• Make certain alarms are wired to a continuous (non-switched)
power line. NOTE: Use standard UL Listed household wire (as
required by local codes) available at all electrical supply stores
and most hardware stores.
