CESF PIR

Ceiling Surface Mounted

PIR Occupancy Switch

Input: 220-240 Vac 50Hz

PLEASE READ THESE INSTRUCTIONS BEFORE INSTALLING THE PRODUCT

DANLERS ceiling surface passive infra-red

occupancy switches (CESF PIR) can be

ceiling mounted on a square pattress box

(DANLERS code: PABO).

The CESF PIR incorporates a passive infra-red

quad sensor to detect movement of a warm

body within its detection zone (diagram A) and

a photocell to monitor the ambient light level.

For optimum coverage recommended

mounting height: 2.4 to 5m

DIAGRAM A (DETECTION)

Upon detecting movement, if the ambient light

is dark enough, the CESF PIR will switch 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 B).

If no more movement is detected within a

pre-selected time, then the CESF PIR will

switch 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 B).

CESF PIR also incorporates a sensitivity

adjuster, labelled 'SENS', to reduce the range

and sensitivity of detection (diagram B).

INSTALLATION PROCEDURE

1. Please read these notes carefully before

commencing work.

In case of doubt please consult a qualified

electrician.

2. POSITIONING: The CESF PIR should be

installed to achieve correct coverage of

the area, see diagram A. 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 windy or

drafty conditions (exposed lobbies, open

ceiling voids or near ventilation fans) or

(Presence detection)

near heat sources. To cover large areas

CESF PIRs should be spaced in a 5 metre

grid formation.

3. The greatest energy savings will be made

if each CESF PIR controls an independent

set of lamps. They can be wired in parallel

but this should ideally be limited to three,

see diagram D.

4. Make sure the power is isolated from

the circuit. The CESF PIR should be

connected as shown in diagrams C & D:

L - Live in.

N - Neutral in.

SL - Switched Li

ne out.

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 C & D, 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 C & D, note 2) it will

not enter the start-up mode each time.

TIME, LUX AND SENSITIVITY 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, making

reference to diagram B.

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

CESF PIR may help. With the LUX set

fully clockwise wait for the CESF 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.

Turn the SENS adjuster fully clockwise

for maximum range and sensitivity of the

person detector. Turn anti-clockwise for

reduced range and sensitivity.

TROUBLESHOOTING

The load will not switch on:

• The LUX adjuster is set too low and is

inhibiting the switch.

• The SENS adjuster is set too low.

• 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. Reduce the sensitivity

adjuster or re-site the CESF PIR.

• Please contact DANLERS for further

technical support.
