Wire Free Door Chime Kit Model No.: SC335T
No wiring is required for this Wire Free Door Chime Kit. When the Push Button is pressed, it sends a
wireless signal to the door chime that activates the chime.
Since the operating range is up to 150ft (50metre approx. in open field & at suitable condition), you
can mount or take the door chime virtually anywhere in the home, workshop, office or garden.
However, the transmission range of the wire free signal will be reduced if the signal is transmitted
through a number of walls or ceilings. Metal and UPVC doorframes will also reduce the operating
range.

Installation Guide
a) Push Button Unit: Using the two holes at the back of bell push as a template, mark the fixing
position for the unit. Drill holes and fit wall plugs (if fixing to masonry) and secure the push button
unit with screws onto your front door or the position nearby.
Important: Do not mount the Push Button unit on the UPVC doorframes or metal surface, it will
reduce the broadcasting range seriously.
b) Door Chime Unit: This chime unit can be completely portable or fixed in one place. It has a
slotted hang hole on the rear and it can be easily removed or relocated to another room.
Drill a hole and a fit wall plug (if fixing to masonry) and screw (self-tapping 3 x 16mm screw) to
fixing position. Leave a gap of 3mm between the screw head and the wall. Locate the keyhole slot
on the back of the unit over the screw.
Important: Operate the Chime unit within the operation range, test it before final installation.
