Excel Bedlam Loud Tonecaller
The Bedlam Loud Tonecaller is for use in office or factory areas with high background noise level, and is available
as a Domestic version fitted with a 3 metre cord terminated with a 431A telephone plug, or Trade version
intended to be hardwired to the telephone system after the telephone master socket by an engineer responsible
for the system.
The Tonecaller will emit a loud sound in sympathy with the ringing signal, and will be silent at all other times. It is
factory set to maximum sound output and close proximity could result in hearing damage, therefore it should
not be mounted within 3 metres of persons using the area.
Telephone lines should provide enough current for two or more phones or tonecallers whose RENs add up to 4.
The Bedlam Loud Tonecaller has a REN of 0.75.
Even where the number of phones or tonecallers has been limited there is no guarantee that different types of
phones on the same line will ring,
Installation
Before fixing the unit in position make sure that the tonecaller is not connected into the telephone wall socket,
as an incoming call will activate the unit before you are ready.
The Tonecaller should be mounted high up on a secure vertical wall or upside down from an overhang with the
tonecaller nose facing the direction that the sound is to be projected. Never mount the tonecaller with the nose
facing upwards, since it would then collect dust and / or water and may suffer failure.
Fix the base mounting bracket (1) to the suitable surface via the two slots using suitable screws and wall plugs.
Fix the base unit (2) into the base mounting bracket (1). Make sure that the line cord is routed to the master or
secondary telephone socket so that it cannot be damaged by accident and that any excess cord is secured safely.
Now plug the cord into the telephone socket and the tonecaller is ready for use and will sound when an
incoming call is present.
On the
Trade version
pass one end of the 6-wire telephone cable through the cable gland, after first loosening
the outer clamp nut. Terminating two wires of the cable to the screw terminals marked 1 & 3 (3) or to the
Insulation Displacement Connector (IDC) pins 1 & 3 (4). Now tighten the outer clamp nut of the cable gland onto
the cable to secure it.
Take the nose unit (5) and rubber sealing O-ring (6), passing the red and black wire from the base unit (2)
through the plastic sleeve and O-ring. Terminate them in the terminal block (7) in the rear of the nose, with Red
wire to terminal marked RED and Black wire to terminal marked BLACK. With the O-ring in place fit the nose on
to base unit and lock in place using the security screw (8).
Complete the installation by running the cable to the nearest master or secondary socket using standard
