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.
