Secure plate to junction box using mounting screws

4.Secure plate to junction box using mounting screws.

5.With a small wire connector, connect white wire from connector plug to white household wire.

6.Connect black wire from connector plug to black household wire.

7.To interconnect alarms, connect yellow wire from connector to interconnect wire between other combination or smoke alarms. Before starting, see “INTERCONNECTING COMBI-

NATION AND OR SMOKE ALARMS.”

FOR INTERCONNECT: USE #18 AWG MINIMUM WIRE

NOTE: For a single-station combination alarm, cover yellow wire with electrical tape and tuck into junction box.

8.Attach connector plug to pins on back of com- bination alarm. Plug will fit only one way and will snap into place. Gently tug connector to be sure it is attached securely.

9.Position the combination alarm to mounting plate and turn clockwise to lock into place.

10.Turn on power at main fuse box or circuit breaker.

11.Test combination alarm. See “TESTING THE COMBINATION ALARM.”

12.Activate the battery. Remove arrow tab and close battery door. The combination alarm will

beep briefly and the RED light will flash as door is closed.

Interconnecting AC Only and AC/DC (With Battery Back-up) Alarms

•Use #18 AWG minimum solid or stranded wire. When interconnecting, maximum wire length between any two is 1,500 feet for #18 AWG or 4,000 feet for #14 AWG (20 OHMS loop resistance).

•This combination alarm may be interconnected with as many as 11 other Firex model FADCQ, FADC, TPCI, AD, ADC, PAD, G, GC, PG40, or FX1218 smoke alarms, and as many as 6 Firex model ADH heat alarms or COQ-8 CO alarms for a total of not more than 18 interconnected devices. DO NOT connect to any other type or model combination smoke, or CO alarm.

WARNING

While AC and AC/DC smoke alarms can be inter- connected, ONLY when AC power is ACTIVE will ALL units ALARM when one unit senses smoke.

WHEN AC power is DISCONNECTED, INTERRUPT-

ED OR NOT PRESENT FOR ANY REASON, ONLY AC/DC UNITS WILL CONTINUE TO SEND AND RECEIVE SIGNALS AND SOUND AN ALARM IN RESPONSE TO THE PRESENCE OF SMOKE. WHEN power is DISCONNECTED, INTERRUPTED OR NOT PRESENT FOR ANY REASON, AC pow- ered smoke alarms WILL NOT OPERATE. The Model G is an AC-only smoke alarm!

•Connect combination and smoke alarms to a single dedicated AC branch circuit. If local codes do not permit such a wiring configuration or connection, be sure the neutral wire is com- mon to both circuits or phases.
