Description
The Integrated Base Sounders 45681-277, 45681-290
and 45681-300 are fi tted into a round, white plastic
case with an integrated base for accommodating au-
tomatic Fire Detectors or Strobes Series XP95 or Dis-
covery.
The sounders are powered and actuated as modules via
the ADM loop with Apollo/Discovery protocol. They can
be used in combination with a detector or strobe, or as
stand-alone device. For the latter case an optional white
or red plastic lid is available. Furthermore, the sounders
are equipped with an integrated dual-isolator module.
Two different tone types, depending on the sounder
model, are available, and they can be selected during
parameterisation of the Fire Detection Control Panel Se-
ries BC216. If several sounders are actuated in parallel,
they are synchronized by Fire Detection Control Panels
Series BC216 to generate a uniform warning tone.
In case of activation, the sounder is tested acoustically
by means of an integrated microphone.
The address of the sounder as well as the sound level
are selected by means of a DIL switch.
The base sounders have been designed for indoor
mounting. An optional mounting plate is available for
surface mounted cabling.
