Alarm sounder controller has five times greater output
Apollo fire Detectors has increased the current capacity of its DIN-rail sounder controller from 1 to 5 A, enabling it to drive more powerful sounders or up to five times as many conventional sounders or visual warning devices.
This capacity is particularly useful under the Disability Discrimination Act, which requires sounders with a higher sound output. It is also useful for areas with higher background noise.
This sounder controller reports the status of controlled devices to Apollo-compatible analogue control equipment. These devices allow warning devices to be sounded continuously or be pulsed one second on and one second off — individually or in groups. An opto-coupled input monitors the state of the external power supply.
