SImx LHT0179 Installation Instructions Manual

2. Have another person move across the desired
perimeter of the area to be scanned and slowly
adjust the SENS knob until the unit activates.
Note reducing SENS will reduce both normal and
occupancy zones

3. To set the light level at which the lights will
automatically switch “on” at night, turn the LUX
control knob from daylight () to night (  ). If the
lights are required to switch on earlier, e. g. Dusk,
wait for the desired light level, and then slowly turn
the LUX control knob towards daylight while someone walks across the center of the area to
be detected. When the lights activate, release the LUX control knob. You may need further
slight adjustments to achieve your ideal light level setting

4. Once LUX and SENS are calibrated, adjust TIME to suit site requirements.

5. Duplicate these settings for similar locations

INSTALLATION INSTRUCTIONS

SIMX strongly recommend that this sensor is installed by a suitably qualified and registered
electrician.

Please read the entire Installation Instructions and Calibration Settings before installing this
product.

All electrical work must be carried out in accordance with local and national electrical codes as
applicable.

Always switch power off prior to installation.

A means of power isolation must be installed on the circuit for the purpose of safe access for any
internal cleaning, recalibration or maintenance.

This appliance is not intended for installation or calibration by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience or knowledge, unless they
have been given supervision or instruction concerning its use by a person responsible for their
safety.

There are no user-serviceable parts in this product.

Any changes or modifications made or attempted to this product without the prior written approval
of the manufacturer will void any and all stated warranties. This excludes normal calibration of the
Sens, Time and Lux control setting knobs as described in these installation instructions.

IMPORTANT

!

Thank you for purchasing this SIMX PIR Sensor. This sensor is suitable for indoor use, and restricted
outdoor applications only. Please read this manual thoroughly before installation and retain for future
reference.

DETECTION RANGE

This Triple PIR sensor has a normal detection range
in open space of max 22 meters diameter. As this
detection zone is circular, please ensure an adequate
overlap in your layout to eliminate dead-zones.

OCCUPANCY ZONE

This PIR Sensor has a high sensitivity
Occupancy Zone of 6 meters diameter. In
this zone, the sensor will detect small
movement to activate lights or keep
those lights illuminated.

1. The circuit can be switched on for an 8 hour period by using the Manual override. Operation
in this mode bypasses the PIR sensor. This can be activated at any time by using the internal
wall switch or circuit breaker.

2. Toggle the internal wall switch/circuit breaker twice (off/on/off/on) within 3 seconds. The circuit
will now be switched on continuously for 8 hours or until switched back to Auto mode.

3. To switch the unit back to Auto mode, toggle the internal wall switch/circuit breaker twice (off/
on/off/on) within 3 seconds (Same operation as activating Manual Override). The unit will return
to Auto mode.

TIME SETTING:

The duration time is the length of time the circuit stays ‘on’ after activation. The duration time can be
adjusted from (10±5) seconds to (40±5) minutes. Rotating the TIME knob from (+) to (-) will reduce
the duration time. Note: Once the circuit has been triggered by the PIR sensor any subsequent
detection will start the timed period again from the beginning.

SENSITIVITY SETTING (REACH): The sensitivity set to (+) provides the maximum distance

which PIR Sensor can be triggered by body movement. Turning the SENS knob from (+) to (-) will
decrease both the sensitivity and activation zone.

B: RECESS MOUNTING TO CEILING (FIGURE 2B)

1. Unscrew the Cable Clamp, remove the Junction Box and Terminal Block.

2. Discard the Base piece for recess mount applications – not required

3. Connect circuit wiring to the terminal block as labelled.

4. Refit the Terminal Block, Junction Box and Cable Clamp.

5. Fit springs, carefully lift the spring clips into the 82-88mm diameter hole, and recess the
PIR to the ceiling. The spring clips will secure the unit. Refit the front cover.

1. Remove the front cover

2. Unscrew the cable clamp, and remove the Junction Box and Terminal Block

3. Use the Base as a template to mark the screw holes into the ceiling. Pre-drill the lining to
depth of 35mm and fit the plastic plugs, and then affix the Base securely. Care should be
taken to avoid drilling or screwing any concealed services inside the ceiling void.

4. Connect circuit wiring to the terminal block as labelled.

5. Secure the Junction box & Terminal block to the PIR and tighten cable clamp over Mains
Cable.

6. Carefully align the male terminal pins, click the PIR body onto the Base then re-fit the front
cover.

INSTALLING THE SENSOR

Before commencing any electrical work, ensure the mains supply is isolated by switching off
and removing the relevant fuse.

Exceeding the maximum rated load may cause overheating and probable failure of this sensor.
Please exercise care!

LIGHT CONTROL SETTING:

The Lux control is a built-in sensing device (photocell) that detects daylight and darkness.
() position denotes the light can activate during daylight and night. (  ) position denotes

the light can activate only at night. You can set the unit to operate at the desired switch on
level by adjusting the LUX knob

SETTING THE CONTROLS

1. Put the LUX control knob to light () position, turn the wall switch on and wait half a minute

for the control circuit to stabilize. At this stage ensure that the TIME control knob is set at
minimum duration time (-) position. The connected circuit will now switch on and remain on
for about 30 seconds (within 60 seconds).
