Interconnecting Two Battery (DC) Only Alarms
When interconnecting compatible DC alarms, location is important. Do not locate alarms on ceiling joists or other obstructions.
NOTE: 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).
1.Follow Steps 1 to 3 in “INSTALLATION FOR BATTERY (DC) ONLY OPERATION” for alarms being interconnected.
2.Thread the low voltage wire through the inter- connect hole drilled in the mounting surface. Strip off 1/2” of insulation and attach to the alarm connector with a wire nut.
3.Connect yellow and white wires to the connec- tor using a wire nut. Connect yellow to yellow and white to white for proper operation. Do not connect black wire.
4.Insert the screw anchors into the holes drilled for the mounting slots. If necessary, gently tap the anchors with a hammer until they are flush with the mounting surface. Repeat Steps 2 and 3 with the other Firex alarm.
5.Attach the mounting plate to the mounting surface with the mounting screws provided.
6.Plug alarm connector into alarm. Feed wire through hole in mounting surface. Position the combination smoke and CO alarm on the mounting plate and turn clockwise to lock the unit into place.
7.Activate the battery. Remove the arrow tab and close the battery door. The combination alarm will beep briefly and the RED light will flash as the battery door is closed.
8.Test the alarm with both local and interconnect tests (See TESTING AND MAINTENANCE.)
