This product requires to be permanently powered which is achieved through the switched live. As such, some LED and CFL lamps may glow or flash whilst this product is in the “OFF” status. This glow/flash can be eliminated by adding the Timeguard FLA01 Light Adaptor or ZV900 Automatic switch load controller to the circuit.

Selecting a Location

• For indoor use only i.e.: hallways, dining room, basement, utility rooms, and garages, etc. To replace existing one-way light switches.
• Since the ST910 is sensitive to temperature changes. Avoid mounting directly above heat sources or exposed to direct sunlight.
• Avoid mounting the motion sensor switch where it can come into contact with water or rain.
• For best results mount the sensor switch to detect objects moving across it.
• The ST910 can be mounted at heights between 0.85m to 1.5m.

The optimum height for detection is 1m, which we recommend to achieve the 10m range. Please note that mounting it any higher will not give the same performance.
Detection

Installation

5.1 Ensure the mains supply is switched off and the circuit supply fused are removed or the circuit breaker is turned off, until you have completed the installation.
5.2 Remove the existing light switch, and transfer the wires to the ST910 (See Fig 6. Connection Diagram).
5.3 Secure the unit to the backbox with the fixing screws provided, forming the cables during installation to avoid any entrapment and cable damage.

Connection Diagram

In the event of ST910 not being able to power on during installation due to the high impedance of the LED lamp, the installer is advised to connect the X1 capacitor (without polarity) in parallel with L/N.
Recommended X1 Capacitor value.

• X1 0.22uf / 275V or
• X1 0.33uf / 275V or
• X1 0.39uf / 275V

DIP Switch and Slide Switch

Note: The DIP Switch located on the back of the light switch can be used to enable or disable the Manual ON/OFF function when using the Slide Switch. By default, this will be set ON.

• If the DIP Switch is set to the ON (upwards) position, the Slide The switch can be used to turn your lights ON/OFF manually or can be set to AUTO for motion control only.
• If the DIP Switch is set to the opposite (downwards) position, the Slide Switch will be disabled and your lights will turn ON using motion only.

Walk Test

Note: If the DIP Switch is set to the ON position, also make sure the Slide Switch is set to the AUTO (middle) position.

• Set the On-time adjuster fully anticlockwise to the min 10s position.
• Set the Lux adjuster fully clockwise to the SUN symbol.
• The light switch will now operate during the daytime as well as at night, illuminating your lights for approx. 10 seconds each time. This allows testing to be carried out to establish whether the sensor is covering the required area.
• Walk-in front and around the sensor to establish the detection area. The sensor will detect motion within an 10m diameter (walking across), and within a 3m range (walking towards) with the sensor mounted at 1m.
• As you cross the detection `zone’ your lights will illuminate.Now stand still until your lights extinguish (this should take approx. 10 seconds).
• Start moving again after 2 seconds until your lights turn ON.
• Repeat the above, walking at various distances and angles from the light switch. This will help you confirm the detection pattern.

9. Setting up for Automatic Operation

• Turn the Lux Adjustment fully anti-clockwise to the Moon symbol.
• Turn the On-time Adjustment to the desired setting (10 seconds Minimum to 15 minutes Maximum).
• When the ambient light level reaches the level of darkness at which you wish the lamp to become operative once motion is detected (i.e. at dusk) SLOWLY rotate the control in a clockwise direction, whilst moving (e.g. your hand) in front of the sensor, until a point is reached where the lamp illuminates.
• Leave the Lux Adjustment set at this point.
• At this position, the unit should become operative at approximately the same level of darkness each evening each time motion is detected.

Adjustments

• If you find that your lights switch on when it is too dark, turn the Lux Adjustment clockwise towards the Sun symbol.
• If the light is in operation when it is too light, turn the Lux Adjustment towards the Moon symbol.
