The IS FlashDome is an intrinsically safe strobe for use in hazardous areas. Certified to ATEX and IEC Ex, the IS FlashDome is designed for use in Zones 0, 1 & 2.
In order to be intrinsically safe, the IS FlashDome must be powered via an approved 28v 300Ohm zener barrier or galvanic isolator.
Suitable barriers and isolators are available from Vimpex.
The LF-PE-4111 Conventional Type Photoelectric Smoke Detector uses a specialized smoke chamber design, which could sense the presence of smoke particles produced by fast combustion or slow smoldering fire. Combining fire algorithms stored on its memory with the special three part design of the smoke chamber and given the photo-sensor’s viewing angle, the detector can effectively sense both white smoke and black smoke with virtually no false alarms. A maximum of thirty smoke detectors can be installed on a single zone.
