LightSpot presence-detecting washroom controls

Only suitably qualified personnel should install this equipment.

LightSpot washroom controls are high performance presence detectors with photocell. The photocell can
operate in three modes: Passive, Active or Disabled. Further information can be found overleaf.

Fixing

UC1201PSM / UC1221PSM - The housing may be secured to a hard surface or a BESA box. The unit fits into
the housing with a simple bayonet action.

UC1201PF / UC1221PF - Depth required behind ceiling: 62mm from front flange plus an allowance for the
minimum bend radius of the cable. Sinking box fits into an 89mm diameter hole in ceiling tile or plasterboard
ceiling. To avoid damage to ceiling tile, do not overtighten. No access above the ceiling is necessary.

Note: Do not mount within 25cm of a luminaire.

Solenoid Valve

The solenoid valve must be plumbed into the water feed to the urinal header tank and connected to the
LooSpot detector using 230V cable.

The required direction of water flow is shown on the valve. Avoid contamination by swarf, flux etc.

Off Delay

Independent Off Delays may be set for each output between 5 and 35 minutes. A 10-second Off Delay is
available for walk-testing the product. In a typical office environment a 20-minute Off Delay is usually satisfactory

Movement Detector Operation (Automatic / Semi-Automatic)

Where absence detection is required (ie the user manually turns lights ON if required but lights still turn off
automatically once an area is vacated), semi-automatic operation can be set via the programmer. It should be
noted that this mode of operation affects only the switched-live output. Where semi-automatic operation is
required on both outputs, please contact Ex-Or for assistance.

Power Up Setting (On/Off)

Set to ON the detector will automatically switch its outputs on when Mains is applied. If set to OFF, the detector
will power up without turning its outputs on, wait for 15 seconds and THEN look for movement. Only if the area is
occupied will the outputs switch on at this time. The detector must be set to Power Up ON when used in
conjunction with semi-automatic operation.

Photocell Operation (Passive/Active/Disabled)

Both the single-output detector and the dual-output detector have an in-built photocell. On the dual-output
detector the photocell does not affect the volt-free output - ie the volt-free output will turn ON regardless of natural
light levels when occupancy is detected. The photocell has three modes of operation - Passive, Active and
Disabled. Its operational behaviour is governed by the setting chosen and by the values stored in the Upper and
Lower thresholds (see diagram overleaf).

Passive - The photocell will inhibit turn-on of the controlled load if sufficient natural light is available. It will not turn
the load off whilst an area is occupied

Active - The photocell will turn the controlled load on and off as required whilst natural light levels fluctuate during
a period of occupancy. This mode of operation operates in conjunction with a passing cloud timer (PCT). The
PCT is asymmetrical in operation - the load will be switched on immediately should natural light levels fall
beneath the lower threshold, however, the load will not turn OFF should natural light levels increase beyond the
upper threshold level unless that increase is constantly above the threshold for the duration of the Off Delay.

Disabled - The photocell has no effect regardless of natural light levels.

24hr Cycle (Yes/No)

If the detector has seen no movement for 24 hours, the output (selectable on dual-output version, default =
volt-free) will be switched ON for the duration of the time delay, if 24hr Cycle is set to ON. Used in conjunction
with a suitable valve the need for separate urinal flush control is removed.

Commissioning

The units are supplied with factory default settings (power-up on, fully automatic operation, a 20 minute off delay,
no 24hr cycle, photocell disabled). Programme using the MLS Digital Programmer with LCD display (HP2000), or
the LightSpot Programmer (HP10) incorporating 12 dil switches.

Walk-test Mode

Walk-test mode is used to check that the detector is operating as required. The short off-delay enables the
installer to check that lights are switching on when movements are made at the edge of the detection zone. It is
easier to carry out a walk-test when the photocell is not holding the lights off. cont.

1. Change the programmed Off Delay to 10 seconds using either an HP10 or HP2000.

2. Move around the area that is being controlled, stopping for 10 seconds to allow the lights to switch off, before
moving and triggering the lights back on. Re-programme the desired Off Delay once testing is complete.

Setting the Photocell (Photocell only affects the ‘Live Out’ output)

1. Wait until the time of day when the ambient light level is equal to the level at which you want the photocell to

become active.

2. Using the HP2000, select ‘Set Light Level’ from the Utilities menu and press OK while pointing at the

detector to store the current light level - the lights must be on prior to starting this process. The detector
stores two values in Lower Threshold and Upper Threshold (see diagram). This procedure can also be
accomplished by using the HP10 Basic Programmer’s ‘Store’ button, however editing of stored threshold
values is not possible with the HP10.

3. If required, these values can be manually edited via the HP2000. Please note, these are not Lux levels but a

representation of the light levels perceived by the detector at the time of the store command.

Note: If the photocell is set to Passive, only the value in the Lower Threshold is relevant.

If the photocell is set to Active, once the ambient light level drops below the Lower Threshold value, the

lights will turn ON. If the ambient level exceeds the value of the Upper Threshold for the duration of the off­delay (Passing Cloud Timer) then the lights will turn ON. If the photocell is set to ‘Disabled’ when a Set Light
Level operation is made, it will revert to operating in Passive mode.

Washroom Mode

Both the single-output and dual-output version of this product allow the control of water for washroom
management applications (urinals). In order to maintain good standards of hygiene the products feature a
washroom mode (24hr Cycle) that, if enabled, ensures that when urinals have not been used for 24 hours
(i.e. the controlled area has been unoccupied), a hygiene flush occurs. Please note that when used on the
single-output unit (controlling lighting and urinals), it is not possible to have the photocell influence the output
status as this could prevent flushing of the urinals. On the dual-output unit the ‘flush’ will occur on the volt-free
output although this can be changed via the HP2000 Programmer.

Important Additional Notes

1. All terminals on this product are provided for final connections. It is not intended that the product be used as a junction box

for looping cables.

2. A means for disconnection must be incorporated in the fixed wiring in accordance with the current wiring regulations.

3. This equipment switches lights no more frequently than would a responsible human occupant. However, manufacturers of

some lighting types (e.g. ‘2D’ luminaires) may specify a maximum number of switching cycles in order to achieve a
predicted lamp life. Please check with the manufacturer of the luminaires to ensure that they are compatible with
automatic controls in this respect.
