INSTALLATION

Mounting:

Mount the unit to a firm

venical

surface (flat on wall or

in corner). The wall wiring hole should be no more than

64 6' (8rnm) diameter.

Remove the front cover as shown in Figure 1.

Remove the screw holding the PC board in the

detector base (the screw is located at the center

the

board) and temporarily

remove the board

@andIs PC board carefully).

Refer to Figure 2. Knockout holes in the base are

availa&

for normal surface mounting on a wall

(holes 'A'). or for comer mounting (holes '8').

Break out only those mounting holes required.

Feed wiring emerging from the wall through the wire

access slot at the bottom of the detector base.

Make sure wires have sufficient sbdr lo allow the

PC board lo slide up and down freely when the

wires are subsequently connected lo the terminals

on the board. Then mount the base.

Re-install lhe PC board (with renninal block dosest

to the wiring access slot in the base). Before fully

lightening the holding screw, make sure the board

is positioned tor the appropriate selling on the

graduated

scale

(see

'B.

Vertical

Pattern

Adjuslment'. and Fig. 3).

Refer to WlRiNG CONNECTIONS before replacing

the front cover.

B. Vertical Pattern Adjustment

The prelection pattern provided by the lens in Use Can

be raised or lowered by re-positioning the PC boatd n

the detector. A graduated scale to Ihe right of the

board (see Fig. 3) indicates the approximate number of

degrees by which the pattern can be raised (max. l 4 '1

or lowered (max. W). The detector is normally shipped

with the board set to the 0" positlon. To make this

adjustment. remove the cover on the detector and

loosen the screw holding the PC board (the screw is

located at the approximate center of the board). Slide

the board upward or downward by the

number

degrees required, lhen tighten the holdi

screw again.

After any adjustment. you must conduct a walk test 10

ensure proper coverage of the area to bs protected. as

indicated under Test Procedures-.

C. Lens Masklng:

The masking strips lhal have been supplied are

designed for application to one or more lens segments

to prod&Y? a protection pattern pattern that suits the

parlicular

.requirements

of the protected

area.

lndiiual

masking slrips have been provided

for

each

of the lens segments on the standard lens supplied

with the PIR. Simply peel off the appropriate pressure-

sensiliie adhesive strip(s) and apply over the desired

IenS segment(S). Be sure lo affix the masking strips lo

the inside of the lens (not the outer, smooth ade).

Each lens segment that is masked results in the

elimination of one zone of protection from the coverage

paltern. By masking segments of the lens. you can

adjust lhe coverage lo suit the area lo be prolected. or

eliminate coverage from areas where you anticipate

environmental

disturbances

that might reduce the

PIRL stabilii (a heater or

other

heat-producing objecl

for example).

WIRING CONNECTIONS

Bring all wires in through the wire access slot near the

terminal bk& and conned lo the screw terminals (see

Fig. 3 for wiring details). Beal all openings in the base

wilh loam or RTV (not supplied) lo prevent drafts or

insects from entering the unit. Apply power on/y after

aI/ amfx3cMns haue

been made and are &pee&d.
