Devices of alarm of high performance for signaling of zone 0
15 January 2014
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.
