Activator and Momentary Fitting

When connecting with Elkay activators use 

three core cable connecting the live in, 

live out and trigger terminals as shown in 

Diagram 1. Please note that the TRIGGER 

terminal is the third terminal between 

live out and neutral. Retractive or 

Momentary switches will work with this 

product when looped with the live in 

and trigger terminals.

Operation of the Unit

1. Press the pushbutton/touch pad and the 

red LED will light up. Your light source or 

appliance will now be switched ON.

2. At any time during the working of the 

light source or appliance, the 

pushbutton/touch pad can be pressed 

to reset the timing sequence to the 

originally set time, e.g. when the timing 

period is 30 minutes. If pushbutton/

  touch pad is pressed 15 minutes into 

the sequence, the timer will re-set for a 

further 30 minutes.

3. To end the timing sequence prematurely, 

press and hold the pushbutton/touch 

pad until the red LED fl ashes 

continuously indicating the last minute 

of operation. Your light source or 

appliance will be switched OFF, after 

one minute.

4. At one minute prior to the end of the 

timing sequence, the red LED will begin 

to fl ash continuously for the last 

minute of operation. The blue locator 

  ring will then illuminate once the light 

source or appliance has gone off .
