The world's most advanced alarm annunciator
RTK Engineering is launching what is claimed to be the world's most advanced integral logic alarm annunciator.
This ensures that all colours are matched to obtain consistent brightness across the range including white and blue.
Up to two LED clusters can be driven from one IIC power source.
The lamps provide a minimum of 100,000 hours of service life.
The clusters are Atex certified to Ex II 1G, EEx ia IIC T4 and are suitable for zones zero, one and two and for all gas groups.
When used in hazardous areas, the clusters must be powered through suitable intrinsically safe isolators or barriers.
RTK makes a range of suitable interfaces such as the S951 and S953.
The clusters are simple to install on any panel door.
The lens simply drops through a standard 22.5cm diameter hole and the body is screwed securely from the rear, providing a seal to the panel of IP65.
The clusters can be linked into either the LN1000 intrinsically safe alarm annunciator or one of a number of safe area annunciators.
Also, a range of matching pushbuttons and selector switches can be supplied.
With the LED's lower power consumption, low heat dissipation and long life expectancy, the DA170 is suitable for safe and hazardous areas alike.
