ff.,

 

you

 

can

 

install

 

the

 

sensor.

 

How

 

and

 

where

 

you

 

anchor

 

the

 

optical

 

head

 

and

 

electronics

 

enclosure

 

depends

 

on

 

the

 

type

 

of

 

surface

 

and

 

the

 

type

 

of

 

bracket

 

you

 

are

 

using.

 

You

 

can

 

mount

 

the

 

optical

 

head

 

through

 

a

 

hole,

 

on

 

a

 

bracket

 

of

 

your

 

own

 

design,

 

or

 

on

 

the

 

available

 

bracket

 

accessory.

 

You

 

may

 

need

 

to

 

“snake”

 

the

 

fiber

 

optic

 

cable

 

through

 

and

 

around

 

any

 

obstacles,

 

such

 

as

 

beams,

 

walls,

 

support

 

columns,

 

etc.,

 

or,

 

if

 

your

 

installation

 

requires,

 

through

 

conduit,

 

before

 

attaching

 

the

 

end

 

to

 

the

 

electronics

 

enclosure.

 

(Do

 

not

 

attach

 

until

 

you

 

aim

 

the

 

optical

 

head.)

 

The

 

cable

 

can

 

be

 

disconnected

 

from

 

the

 

electronics

 

box

 

for

 

aiming

 

or

 

threading

 

through

 

conduit

 

during

 

installation.

 

The

 

cable

 

is

 

keyed

 

and

 

can

 

only

 

be

 

inserted

 

one

 

way

 

into

 

the

 

electronics

 

enclosure.

Cable

 

Tighten only after securing connecting sleeve 

Note keyed connecting sleeve (can be 
inserted only one way - slot must face mode 
switches) 

Push connecting sleeve in until it stops 
(approx. 15 mm / 0.6 in) 

Tighten screw (finger tighten only)
