Devices of alarm of high performance for signaling of zone 0

And2S has launched to the market his acoustic alarms and devices combined intrinsically safe and high performance with box of aluminium. The alarm IS-D105 and the device combined IS-DL105 are certified according to the norms IECEx and ATEX for zone 0 and the box sealed of aluminium of maritime degree IP66 is fosfatada and recubierta of dust sinterizado, offering like this a better protection for applications inside and out of the coast.

The powerful alarm produces until 105 dB(To) to a metre and has of 49 tones of alarm and 2 phases of additional and selectable alarm to distance. For specific applications, can design with frequencies and configurations of tone customised. The alarm can combine with a luminous buoy that includes a matrix of 6 LEDs of high intensity.

The alarm and the luminous buoy can activate through an only barrier Zener or aislador galvanic. Alternatively, the acoustic and visual elements of the model combined IS-DL105 can control individually. When they are wired up to a common electrical supply, the alarm includes a function of acceptance of alarm. Closing a pair of external contacts (that is to say, a switch pulsador) the operator can silenciar the alarm during periods established from among 5 seconds and 2 hours. The luminous buoy continues destellando to the double of his normal frequency, indicating that it follows active the state of alarm. If after the time preestablecido the state of alarm persists, will activate again the acoustic alarm.

And2S is specialised in the design and manufacture of devices of acoustic and visual signaling and signals of warning for dangerous areas, industrial applications and maritime surroundings.
