MOUNTING INSTRUCTION

1. A qualified electrician should mount the bell.
2. It is recommended to use 0,5 mm
wires for the bell electrical system. The wire type should be appropriate for local
circumstances.
3. The bell may by powered by 8V AC voltage only. An external 230/8 V AC
transformer is needed (e.g. TRM-8 of ZAMEL). It is necessary to buy a
transformer independently; it is not included in the bell kit.
4. It is necessary to prevent a phase wire against shortcuts and overloads by
means of an overcurrent switch or a safety fuse with an appropriate rated
current and electrical characteristic.
5. In necessary to disconnect 8V AC mains before you connect the bell. Check if
there is no voltage between power leads by means of an appropriate gauge.
6. Select a place for the bell mounting and drill two mounting holes in the wall
and insert studs into the holes. The hole spacing should be equal to 43 mm.
Drive the shorter screw into the lower hole until its distance to the wall is 5 mm.
7. Remove the separator.
8. Strip the bell electrical system wire ends insulation (approximately 8 mm in
length) and connect the wires to appropriate terminals (fig. 1). You can lead
the system wires through the spacer after the round protection insert removal
(fig. 2a) or through the casing. In this case it is necessary to cut thin areas in
the top part of the casing (fig. 2b).
9. Screw down the bell by means of the longer screw. Place the screw into the
upper hole. Insert the shorter screw end between the bell protective fins,
which are placed in the lower part of the casing (fig. 3).
10. Turn on the mains.
11. Press the bell push button to check if the bell operates properly.
NOTE! Check if there is no voltage between power leads before you remove
the bell cover!
