MOUNTING
The฀detector฀base฀mounts฀directly฀to฀3-1/2฀inch฀and฀
4-inch฀octagon฀boxes฀and฀4-inch฀square฀boxes,฀with฀
or฀ without฀ plaster฀ rings.฀To฀ mount฀ the฀ base,฀ remove฀
the฀decorative฀ring฀by฀rotating฀it฀in฀either฀direction฀to฀
unhook฀the฀snaps฀before฀separating฀the฀ring฀from฀the฀
base.฀Use฀the฀screws฀supplied฀with฀the฀junction฀box฀
to฀attach฀the฀base฀to฀the฀box฀through฀the฀appropriate฀
slots฀in฀the฀base.฀
See฀ Figure฀ 1.฀ Position฀ the฀ decorative฀ ring฀ around฀
the฀base฀and฀rotate฀it฀in฀either฀direction฀until฀the฀ring฀
snaps฀into฀place.฀
INSTALLATION฀GUIDELINES
Allowable฀loop฀resistance฀is฀an฀important฀specication฀
for฀control฀panels฀as฀well฀as฀for฀smoke฀detectors฀and฀
their฀ bases.฀ The฀ alarm฀ system฀ cannot฀ be฀ expected฀
to฀ operate฀ correctly฀ if฀ system฀ components฀ have฀ in-
compatible฀ allowable฀ loop฀ resistances.฀ Therefore,฀
before฀beginning฀installation,฀refer฀to฀the฀control฀panel฀
manufacturer’s฀loop฀resistance฀specication฀to฀ensure฀
that฀it฀is฀listed฀as฀compatible฀with฀the฀Notier฀base฀and฀
smoke฀detector฀being฀installed.
All฀ wiring฀ must฀ be฀ installed฀ in฀ compliance฀ with฀ the฀
National฀Electrical฀Code฀and฀all฀applicable฀local฀codes฀
and฀ any฀ special฀ requirements฀ of฀ the฀ authority฀ hav-
ing฀jurisdiction,฀using฀ the฀ proper฀ wire฀ size.฀The฀con-
ductors฀ used฀ to฀ connect฀ smoke฀ detectors฀ to฀ control฀
panels฀and฀accessory฀devices฀should฀be฀color-coded฀
to฀ reduce฀ the฀ likelihood฀ of฀ wiring฀ errors.฀ Improper฀
connections฀ can฀ prevent฀ a฀ system฀ from฀ responding฀
properly฀in฀the฀event฀of฀a฀re.

this.฀฀After฀the฀detector฀base฀is฀wired฀and฀attached฀to฀the฀electrical฀box,฀position฀the฀shorting฀spring฀against฀terminal฀3.฀
Use฀the฀slot฀in฀the฀retaining฀clip฀to฀hold฀the฀spring฀against฀the฀terminal,฀as฀shown฀in฀Figure฀1.฀This฀shorts฀the฀negative-in฀
and฀negative-out฀leads฀so฀that฀loop฀wiring฀can฀be฀tested฀for฀continuity.
The฀shorting฀spring฀in฀the฀base฀will฀disengage฀automatically฀when฀the฀detector฀head฀is฀removed฀from฀the฀base.฀DO฀NOT฀
remove฀the฀shorting฀spring฀since฀it฀reengages฀as฀the฀detector฀head฀is฀turned฀into฀the฀base,฀completing฀the฀circuit.
TAMPER-RESISTANCE฀FEATURE
NOTE:฀DO฀NOT฀use฀the฀tamper-resistance฀feature฀if฀the฀XR2฀Removal฀Tool฀will฀be฀used฀to฀remove฀detectors฀from฀the฀
base.
This฀detector฀base฀can฀be฀made฀tamper฀resistant฀so฀that฀the฀detector฀cannot฀be฀detached฀without฀the฀use฀of฀a฀tool.฀To฀
make฀the฀base฀tamper-resistant,฀break฀off฀the฀smaller฀tab฀at฀the฀scribed฀line฀on฀the฀tamper฀resistant฀tab฀located฀on฀the฀
detector฀mounting฀bracket฀(see฀Figure฀3A),฀before฀installing฀the฀detector.
฀
To฀remove฀the฀detector฀from฀the฀base฀after฀it฀has฀been฀made฀tamper฀resistant,฀remove฀the฀decorative฀ring฀by฀rotating฀it฀in฀
either฀direction฀and฀pulling฀it฀away฀from฀the฀base.฀Then,฀insert฀a฀small฀screwdriver฀into฀the฀notch,฀as฀indicated฀in฀Figure฀
3B,฀and฀press฀the฀plastic฀lever฀toward฀the฀mounting฀surface฀before฀rotating฀the฀detector฀counterclockwise฀for฀removal.

For฀signal฀wiring฀(the฀wiring฀between฀interconnected฀detectors),฀it฀is฀recommended฀that฀the฀wire฀be฀no฀smaller฀than฀AWG฀
18.฀However,฀the฀screws฀and฀clamping฀plate฀in฀the฀base฀can฀accommodate฀wire฀sizes฀up฀to฀AWG฀12.฀The฀use฀of฀twisted฀
pair฀wiring฀for฀the฀power฀(+฀and฀-)฀loop฀is฀recommended฀to฀minimize฀the฀effects฀of฀electrical฀interference.
NOTE:฀To฀ensure฀that฀electrical฀connections฀are฀supervised,฀do฀NOT฀loop฀wires฀under฀terminals฀2,฀3,฀and฀5฀-฀break฀the฀
wire฀at฀each฀terminal.
To฀make฀electrical฀connections,฀strip฀approximately฀3/8"฀(1฀cm)฀insulation฀from฀the฀end฀of฀each฀wire.฀Slide฀the฀wires฀under฀
the฀clamp฀plate฀and฀tighten฀the฀terminal฀screw.
