The K24000 audio visual indicator units are robust and compact devices which can be used to fulfil a variety of alarm and indication needs for fire alarm or other 24V DC systems.
K24100-M10 and K24110-M10 units are fitted with red indicators and are intended to provide an audible and visual Fire alarm indication when supplied with a nominal 24V DC from a fire alarm circuit. The K24110-M10 unit has a keyswicth which enables the audible alarm to be silenced.
The standard label fitted to these units describes the unit as a FIRE alarm however, this can be easily changed and a customised label fitted. A template and instructions for creating customised labels is available at http://www.kentec.co.uk/audio.doc.
K24200-M10 and K24210-M10 units are fitted with yellow indicators and are intended to provide an audible and visual indication for any other condition than a fire alarm, such as a PLANT ISOLATED indication. The K24200-M10 unit requires a switched 24V DC supply applied when the indication is required.
The K24210-M10 unit requires a permanent 24V DC supply and will indicate when the keyswitch is operated. The keyswitch also operates a volt free contact accessible at terminals mounted to the PCB which is available to control other systems. All units can be configured such that the internal buzzer can be disabled.
