Strong performer for Zone 0 signalling

This powerful alarm horn produces up to 105dB(A) at 1m with a choice of 49 alarm tones and two additional, remotely selectable, alarm stages. For specific applications, custom tone configurations and frequencies can be engineered. The sounder can be combined with an LED beacon featuring an array of six high-intensity LEDs.

The alarm sounder and LED beacon can be powered through a single Zener barrier or galvanic isolator. Alternatively, the audible and visual elements of the IS-DL105 combination model can be controlled individually. When cabled with a common power supply, the sounder features an alarm accept function. By closing a pair of external contacts such as a push switch, the operator may silence the alarm for set periods between 5 seconds and 2 hours. The LED beacon continues to flash at twice its normal frequency providing indication of an ongoing alarm condition. If after the pre-set time the alarm condition still exists the alarm horn will activate again.
