Byron SX-15 Manual

Wire Free Battery Bell Kit
The wirefree battery bell kit consists of two
separate units:
1. Push button unit (Transmitter)
2. Door chime unit (Receiver)
These units are completely self-contained
and no wiring between them is necessary.
No wiring is required for this wirfree door bell
kit. When the push button is pressed, it sends
a wirefree signal to activate the door bell.
As the operating range is up to 100 metres
(320 ft. approx.), you can mount the door bell virtually
anywhere in the home, workshop, or office. However,
the operating range of the wirefree 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
Push button unit
1. The push button unit is operated by 2 x 3 volt
Lithium batteries (CR2032 - included).
2. Remove the back of the case by pushing in the tab
on the bottom with a small, flat screwdriver.
3. 2 x 3 volt Lithium batteries (CR2032) have been
installed. Simply pull off the isolating strip to allow
the batteries to make electrical contact.
4. Snap the front cover of push button back on and it
is ready to use.
Replacing the batteries. Remove the locking screw
from the battery fastener in the battery compartment.
Insert 2 x 3 volt Lithium batteries (We recommend
Byron model SX-100 - not included), ensure the
battery's polarity matches the internal markings.
Tighten the screw on the battery fastener to hold the
batteries firm in their compartment. Test to see if the
L.E.D. light comes on.

Installation Guide
a) Bell Push Unit: Using the two holes on the back of push button
as a template,mark the fixing position for the unit. Drill holes,
fit wall plugs (if fixing to masonry) and secure the Bell Push
Unit with screws (self-tapping N3 x 16mm screws - included)
in position, alternatively use the double-sided self-adhesive
pad (included), by placing onto your front doorframe or a
position nearby. Please note, the latter is not the most theft
resistant option.
Important: Mounting the push button unit onto UPVC doorframes
or metal surfaces will reduce the operating range.
b) Door Chime Unit: This has a slotted hang hole on the rear,
this hole will enable the chime unit to be hooked onto a
screw and be easily removed or relocated to another room.
Drill a hole and fit wall plug (if fixing to masonry) and screw (self-tapping N3
x 16mm screw included) 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.
Channel Selection
The unit comes from the factory on a pre-set
radio frequency channel. However, should
your door chime activate intermittently for no
reason at all, it is possible that a similar unit
is operating nearby on the same frequency.
The encoded frequency of the push button
(transmitter) and Door Chime (receiver) can
be changed to avoid this problem.
1. Bell Push: Remove the back of the case
by pushing in the tab on the bottom with
CR2032 x 2
a small, flat screwdriver.
Door Chime Unit: Slide open the battery compartment.
2. There is 4 position dip switch marked 1,2,3,4. Use a small screwdriver to
alter the dip switch levers to the "On" or "Off" position, which can be altered
to achieve total sixteen (16) possible channels.
