Frequently Asked Questions (FAQs)


What Type of dimming do Ansell offer & how are these wired?

We offer Switch Dim, DSI, Dali & 1-10v (please visit the below links for brief explanation of each + simple wiring diagram)

DD/1, DD/2, DD/3, DD/4

What is Corridor Function?

Corridor Function is a setting of DD dimmable control gear for operation with a PIR (standard on/off). Dimmable control gears reduces light output to 3-5% when an area is unoccupied and increases to full light output when PIR is activated.

Can Ansell LED fittings be dimmed?

Yes, with equipment that facilitates this, normally a dimmable LED driver, along with a suitable dimmer switch. All of our LED products are highlighted in our catalogue as either “dimmable” or “non-dimmable”

What dimmers can be used?

The dimmable drivers mentioned previously will not work with traditional resistive / mains dimmers. For mains dimming, leading or trailing edge dimmers would be required.

All Ansell products listed as DD (Digital Dimming) cannot be used with Conventional dimmers.

DD (Digital Dimming) products are either: DD1 Switch dim, DD2 DSI, DD3 (Dali) or DD4 (1-10v).

Dimming LED Strips

We have many enquiries, asking whether the LED strip can be dimmed. This can be achieved, with both Cobra & Adder, by using the ADDIM75W/12V (switch dim or 1-10V only). Please see ADDIM75W12V Dimmable LED Driver Datasheet and Push-to-Dim Dimming,

Microwave Sensors

How are the microwave sensors set up / adjusted?

Please see the list of fittings & their respective microwave sensors. Installation instructions for each sensor are available for download.

HC005s MWS, HC009S-KD, HC008S


How much strip can be run from 1 driver?

AD30W/12V 4mtrs (Adder) 2mtrs (Cobra)
AD75W/12V 10mtrs (Adder) 5mtrs (Cobra)
ADDIM75W/12V 10mtrs (Adder) 5mtrs (Cobra)

Can the strip be cut?

Yes, but only at the cutting points. The remainder of the strip would become a dead end.

When would the amplifier (ACLED/AMP/TOUCH) be used?

An amplifier can be added to synchronise larger installations. 1 amplifier is required every 5mtrs, after the initial run on Cobra RGB & every 10mtrs after the initial run on Adder.


What are Self-Test Emergency Light Fittings?

These fittings utilise an accurate internal clock which is programmed to interrupt the permanent mains supply at set intervals, thus initiating emergency lighting tests. These units are supplied pre-programmed to initiate short duration tests once every month, a one third duration test after six months and a full duration test once every 12 months.

LED Wiring

What is Series & Parallel Wiring?

LED drivers are supplied either Constant Current or Constant Voltage. Both require the LED chips / modules to be wired differently (CC- Series; CV- Parallel).

Bathroom Zones

What do bathroom zones signify?

Bathroom luminaire installations must comply with legislation. Please see section 701 of BS EN 7671:2008 (17th Edition Wiring Regulations)

Zone 0 – This is inside the bath or shower. Any fitting used in these areas must be SELV and IPX8.

Zone 1 – This is the area above the bath to a height of 2.25m from the floor. In this zone a minimum rating of IPX4 is required. If a 230V luminaire is used, the circuit must be protected by a 30mA RCD.

Zone 2 – This area extends a further 0.6m outside Zone 1. In this zone a minimum rating of IPX4 is required. It is also recommended to have luminaires with a rating of IPX4 around the wash basin (with 0.6m radius of the tap).

Outside Zones - Anywhere outside Zones 0, 1 and 2 are classed as outside zones (excluding specific areas) providing water jets are not used, so the minimum rating is IPX0. If water jets are to be used a minimum of IPX5 is required.

Full details can be found in the IEE Wiring Regulations.


What is LED lighting?

A light emiting diode is a device consisting of a semiconductor which emits light energy when an electrical current is passed through it. LEDs can be used for a variety of lighting applications.

What is Anti-Ligature?

This is a luminaire that is free from points where a cord could be fastened to create a ligature point.
