CEFL PIR

Ceiling Flush Mounted

PIR Occupancy Switch

Input: 220-240 Vac 50Hz

PLEASE READ THESE INSTRUCTIONS BEFORE INSTALLING THE PRODUCT

DANLERS ceiling flush passive infra-red

occupancy switches (PIR) can be flush

mounted into suspended and plasterboard

ceilings (diagram A). They include a 2 metre

connecting flex to make installation quicker

and easier.

Clearance

Springs can either be

hole 63mm or

left closed (down the

64mm (2.5")

side of the product)

diameter

or opened out.

DIAGRAM A

These PIR switches incorporate a passive

infra-red quad sensor to detect movement

of a warm body within their detection zone

(diagram B) and a photocell to monitor the

ambient light level.

For optimum coverage recommended

mounting height: 2.4 to 5m

up to 7m

DIAGRAM B (DETECTION)

Upon detecting movement, if the ambient

light is dark enough, the PIR switch will turn

the load on. The ambient threshold can be

set by the user to between approximately

30 lux and 1000 lux and maximum

(photocell inactive) at the PIR via the LUX

adjuster (diagram C).

If no more movement is detected within a

pre-selected time, then the PIR switch will

turn the load off. This time lag can be set

via the TIME adjuster to 10 seconds, 20

seconds, 40 seconds, 80 seconds,

2 minutes 30 seconds, 5 minutes,10

minutes, 20 minutes or 40 minutes

(diagram C).

INSTALLATION PROCEDURE

1. Please read these notes carefully before

commencing work. In case of doubt

please consult a qualified electrician.

(Presence detection)

2. POSITIONING: The PIR occupancy

switch (PIR) should be installed to achieve

correct coverage of the area, see diagram

B. If the photocell override facility is

required, the switch must be located

above an area where daylight can give

greater illumination than the artificial light.

Avoid locating this product where it is

exposed to draughty conditions (exposed

lobbies, open ceiling voids or near fans)

or near heat sources. To cover large

areas PIRs should be spaced in a 5 metre

grid formation.

3. The greatest energy savings will be

achieved if each PIR controls an

independent set of lamps. They can be

wired in parallel but this should ideally be

limited to three, see diagram E.

4. Make sure the power is isolated from the

circuit. The PIR should be connected as

shown in diagrams D & E:

Brown: L (Live in). Blue: N (Neutral in).

Black: SL(Switched Line out).

NOTE: Terminate the mains cable with the supplied

terminal block (terminal blocks must comply with EN

60998-1 or EN 60998-2-1 and be suitable for 0.75-

1.5mm2 conductors). In order to comply with wiring

regulations, the terminal block must be enclosed in

a suitable wiring box (This should comply with EN

60670-1 or EN 60670-22).

See overleaf for loading details.

START-UP MODE

When the PIR is powered up, the PIR will

switch on the lighting load for 1 minute then

switch it off. After 2 seconds it will switch

on again if it detects movement. With Time

set to minimum the load will stay on for 10

seconds so the detection range can be

easily assessed. If a manual override-off

switch is positioned before the PIR in the

circuit (diagrams D & E, note 1) it will do this

each time the wall switch is switched on.

Alternatively, if the wall switch is placed after

the PIR (diagrams D & E, note 2) it will not

enter the start-up mode each time.

TIME AND LUX SET UP

For convenience, ensure that the TIME is

set to the minimum when setting up the

LUX level. Afterwards set the TIME to a

value suitable for the application.

The LUX is best set up when the local

ambient light is at approximately the

minimum desired working light level, a lux

meter placed on the surface under the PIR

may help. With the LUX set fully clockwise

wait for the PIR to switch off. Rotate the

LUX adjuster slowly anticlockwise (- to +),

whilst waving your hand approximately 1m

below the PIR, until the load switches on.

TROUBLESHOOTING

The load will not switch on:

• The LUX adjuster is set too low and is

inhibiting the switch.

• The moving body is not emitting more

IR than the background. (Person

wearing insulating clothing in a warm

environment)

• Person is too far from the PIR switch, see

detection diagram.

• Person is moving unusually slowly

(perhaps when testing).

The load switches on when nobody is

present:

• Heater causing infra-red variations in a

small cold room. Re-site the CEFL PIR.

• Please contact DANLERS for further

technical support.
