General
The DB952IAS is a range of integrated, self monitoring base sounders with integral short-circuit isolator for use on Series 950 and Series 990 systems. They incorporate a base into which a series 950 or 990 detector, or beacon can be fitted. It may also be used with a red (AS952CAP-R) or white (AS952CAP-W) cap for stand-alone use.
Tones
The DB952IAS sounders support multiple tones. A low tone range is useful in areas such as hospitals where a fire alert is initially intended to warn staff only. The sounder may be set to the high range for general use. In addition to the standard tones in the DB952IAS, a slow whoop tone to Dutch standard NEN2575 is available in the DB952IAS-NEN, as well as a German standard DIN tone version in the DB952IAS-DIN.
Syncronisation
Synchronisation of tones ensures the integrity of the signal—tones from different sounders do not merge into one signal that could be mistaken for a different tone. DB952IAS sounders are synchronised with each other in both ‘alert’ and ‘evacuate’ modes.
Self Test
The acoustic self-test means that the sounder listens to itself when it is switched on. If no sound is detected a fault signal is transmitted when the sounder is polled. The same self-test feature may also be used during commissioning or periodical maintenance testing. The sounder may simply be activated for at least 5 seconds and the control panel checked for a fault signal. If none is received, the sounder is working properly.
