Installation/Operating Instructions for
Time Delay Switch
Part No: TLSN

Thank you for purchasing a quality time delay switch from GreenBrook. Please read these instructions fully prior to initial use.
Every effort has been made to ensure that the guidance information on this sheet will enable the installation of the switch to be carried out safely and correctly.
THIS PRODUCT SHOULD BE INSTALLED BY A COMPETENT PERSON AND IN ACCORDANCE WITH THE CURRENT IET WIRING REGULATIONS, AND BUILDING REGULATIONS.
The TLSN is suitable for controlling incandescent (GLS), fluorescent, and compact fluorescent lighting. The timer can be used on its own, or with other units in a 2-wire (no neutral) lighting circuit, and can therefore be installed on new installations or replace existing single gang switches.

IMPORTANT

All metal boxes must be earthed.
Please ensure that the top and bottom lugs are removed, if fitted, from metal wall boxes before fitting as there is a danger of the common terminal (marked com) fouling a mounting lug and causing an earth fault if boxes having four lugs are used.

INSTALLATION

The TLSN has been designed for mounting on a 20mm or 25mm deep standard BS single gang accessory box. However, it is recommended that deeper boxes are used where extra space is required for additional cables, for example when looping in. Please ensure that there is adequate space for wiring.
It is recommended that if using molded backing boxes, please ensure that the backbox only has two mounting lugs as certain manufacturers do not allow adequate clearance for the Time Delay Switch terminal connections. Some molded boxes also have two locating pips on the mounting face which can obstruct the Time Delay Switch and prevent it from fitting flush. These will need to be ground off.
If mounting on surfaces such as unplastered brickwork or the mounting box is completely true to the wall surface, please avoid over tightening the mounting screws, as this may cause the switch faceplate to distort and in turn lock the plunger in the “ON” position.

OPERATION

The switch is operated by pressing the plunger button. This will “make”. The plunger will gradually return to its original position during the time delay sequence, eventually returning the contacts to their original position. The face-plate is molded in a semi-translucent material and therefore it is normal to occasionally see a flash when the contacts “make” or “break”.

WIRING

The live feed should be connected to COM (common). Contacts are connected when the plunger button is pressed and will stay connected for the period of the time delay.
As these units are designed for lighting circuits, a neutral feed is not required at the switch position.
To use the Time Delay Switch as a normal light switch type operation, connect the “Live Feed” Wire into the COM Terminal, and the “Switched Live” wire into the NO terminal.
Additional switches can be wired in parallel to control the same load (please see diagram below).

TIMER ADJUSTMENT

The timing can be adjusted between 10 seconds and 10 minutes (approx) by turning the brass timing screw in the center of the plate on the back of the unit. Turning the timing screw clockwise will increase the time delay.
