Alarms – Opto-Acoustical
Back to OverviewBS 601 / 602
The alarms BS 60** are used for generating optical and/or acoustical signals in potentially explosive atmospheres. As flameproof or even intrinsically safe versions they can fulfil various tasks - e. g. in underground mines.
Combined Alarms "flameproof"
- Available as optical, acoustical, opto-acoustical, flameproof and intrinsically safe version
- Four different mains AC voltages, from 110 to 1000 V, distinction by different letters within type designation
- Available with intrinsically safe control
- Optical part has a light frequency of 1 Hz with xenon photo-flash lamp
- In case of optical alarms: uv-resistant and impact proof - no protective cage required
- Even light distribution
- Electronical two-tone siren, adjustable up to 107 dB
- Loudspeaker in degree of enclosure protection IP 67
- Difference between types BS 601 and BS 602 is the nominal energy of their photo flashes of 5 Ws (BS 601) and 10 Ws (BS 602)
- Activation of all combined alarms by applying a control voltage of 5 V to 15 V (exception: type BS 601 E)
- Current consumption max. 10 mA
- On request, control is performed via telephone ringing signal
- Special feature type BS 601 E: activation of the alarm by applying a supply voltage of 12 V
Combined Alarms "intrinsically safe"
In addition to the flameproof versions, also the intrinsically safe types BS 601 *I and BS 601 *IS are available. They operate the same way as the types mentioned above.
The alarm BS 601 *I is put into operation by applying a supply voltage. In type BS 601 *IS the supply voltage can remain connected permanently and the alarm is activated by means of an external potential-free contact (e. g. switch, relay or optocoupler).
When applying external control a switch-off lag of 0 - 7 seconds can be adjusted in order to bridge breaks in between telephone ringing signals.
