ADEMCO 655 Installation Instructions Manual

GENERAL INFORMATION:

The No. 655 provides 8 zones of wide-angle coverage with range of up to 30

feet.

All models have the following important features:

*

High precision,

computer-designed parabolic optical system.

*

Dual element pyro-electric sensor.

*

Precision die-cast optical head for maximum RF1 protection and accurate

optical alignment.

*

Pre-declined zones for fast and,easy installation.

l

Separate pan and tilt control for convenient pattern adjustment to

achieve desired coverage or avoid hazards.

*

Zone direction not observable when cover is in place.

l

Wall/corner mounting plate for fast and easy installation.

The No. 655 requires power from either a 6V.DC or 12V.DC source that can provide

4omA and at least 4 hrs. of standby power.

The detector will operate at all times, regardless of whether the control to

which it is connected is ARMED or DISARMED. Whenever (and while) motion is

detected, the unit's LED will light and its relay contacts will transfer.

PRINCIPLE OF OPERATION:

The optical system divides the area into a series of protective zones. A special

sensor measures the level of far infrared energy in each zone.

When an intruder

crosses or enters any zone the resulting change in infrared energy is detected

and an alarm condition will exist.

The sensor does not respond to visible light or changes in the background tem-

perature of the room.

Because a passive infrared device employs no transmission of any kind, any

number of units may be used in the same area.

Far infrared energy does not penetrate most building materials (even window

glass) so the unit responds only to motion inside the room.

COVERAGE CONSIDERATIONS AND TYPICAL IAYDDTS:

The pattern of protection provided by the 655 includes five main zones which

span an angle of 75";

and three downward zones as shown in Diagrams 1 and 3.

The entire pattern may be'panned left or right up to 20°.

www.PDF-Zoo.com

The optical system has been designed to give proper coverage'based upon a typical

mounting height of 7'.

However,.the unit may be mounted at any height between

7' and 9' to achieve a proper 30' pattern.

If the unit is to be mounted higher than 9', perhaps as high as 12', or it

it is desired to obtain a range of less than 30' for a particular installation,

the optical head may be tilted downward.

Combinations of mounting height and

"tilt" can be used to obtain coverages as shown in Diagram 3. To adjust the

tilt of the optical head, grasp the metal casting firmly between thumb and

index finger at both sides (where a ridge is provided): pull gently forward

until assembly is free,

then set the tabs on the casting into the desired notches

on the bracket and release.

See Diagram 2.

IMPORTANT: Do not touch the reflector

or sensor surfaces.

"Dead" Zone Caution:

Note in Diagram 3 that for several tilt position/mounting

height combinations there are indicated "dead zones" within which a person

could be moving and not be detected by any of the unit's coverage zones. In

general, these dead zones are apt to be present as the unit's mounting height

is increased and its coverage pattern is tilted downward.

SELECTIN A MOUNTIN LOCATION:

The No. 655 Passive Infrared Motion Detector responds to changes in energy

which occur when an intruder moves into or out of a zone.

Best coverage will

be obtained if the mounting site is selected such that the likely direction

of intruder motion is ACROSS the pattern.

See Diagram 4a, b and c.

ItlSTALLATlOM AND YIRIWG:

Passiwe.1.R. units are remarkably resistant to false alarm hazards but the

following recommendations should be observed:

'

Avoid locating unit where central heating radiators, live fires or outlet

ducts could be within the protective zones.

r

Avoid locating the unit in direct sunlight or directly above strong sources

of heat.

Avoid locating unit on unstable surfaces.

Avoid running alarm wiring close to heavy duty electrical cables.

After wiring is complete, the wire entry opening in the case should be sealed

to prevent entry of air movement and drafts into the PIR unit.

muNTIN6:

IMPORTANT: Be careful during installation or adjustment NOT TO TOUCH THE REFLECTOR

DR SENSOR SURFACES. WHEN POSITIONING THE HEAD ASSEMBLY, GRIP THE DIE-CAST

BODY ONLY, AS SHOWN IN DIAGRAM 2.

1.

Mount the wall plate to a firm and vertical surface (flat on wall or in

corner) at the recommended height (see previous section).

Orient the

plate -so that its unit mounting hooks are at the bottom; If wiring is

provided from a hole in the mounting surface, center the mounting plate

with the bottom of the pl.ate just above the hole.

This will align the

wires with the wiring entry in the case when the unit is secured.

See.

Diagram 5.

2.

Remove front cover by loosening,.the retaining screw.

3.

Push the two special hex head screws provided through the two retainer

type mounting holes at rear of,the plastic case, if this has not already

been done.

4. Attach unit to wall plate, as follows:

Engage lower hooks on wall plate

into case bottom (see Diagram 5) and secure unit to wall plate with the

two hex'head screws provided; Note:

to gain access to screws.

Move detector head left or right

Do not remove detector, head from unit as damage

to mirror may result.

Use only the wiring entry at the lower rear of the case and carefully feed

the wires along the underside of the printed circuit board. Avoid contact

between bare conductors, screws or metal parts likely to contact the printed

circuit.

Avoid unnecessary splices and loops within the unit. Check all connections

carefully.

The meter's negative lead should be connected to terminal 2 on the connector

block (input ground).

The meter should be set to the 2.5V.DC range.

Mask the detector's optics so that motion cannot be detected. The meter should

indicate approximately 1.6VDC.

Remove the mask covering the optics, remain

motionless and allow time for the meter to settle.

Motion into any,of the

detector's 8 zones will cause the meter to deflect above or below the 1.6V

nominal DC level. Meter variations oft 0.5VDC will trigger the unit causing

the LED to illuminate and the alarm relay to transfer.

Final Test:

Double-check all connections. Replace the front cover and secure the holding

screw.

Walk-test unit with cover in place.

Test operation by walking through

the protective zones and observing walk-test LED.

Note: The absolute range of all Passive I.R. units is subject to variation

because of different types of clothing, backgrounds, and ambient temperature

changes.

For this reason,

ensure that the most likely intruder routes are

well within the protective zones and that walk-testing is carried out. along

these routes.

MINTAIWIWG PROPER OPERATION AND COVERAGE:

In order to maintain the detector in proper working condition, it is important

that the

following be observed by the user.

1. Power should be provided at all times.

The unit's DC source should have standby power available for

at least 4 hrs of operation during emergencies.

Units should never be re-aimed or relocated without the advice or

assistance of the alarm service company.

2.

3.

4.

The physical surroundings of the protected area should not be changed.

If furniture or stock is moved,

or air-conditioning or additional

heating is installed,

the system may have to be readjusted by the

alarm service company.

Walk-tests should be conducted at least monthly to confirm continued

proper coverage by each detector.
