The Type Y05/ISA Audible Alarms produce a loud audible warning signal within a hazardous location. To avoid confusion between alarm signals the alarm can be configured in the field to generate any one of 11 unique first stage alarm signals. Eight of these signals can produce distinct second stage alarms signals when the supply voltage to the unit is reversed.
The alarm can be configured to generate simple continuous tones, single or dual tones with fast or slow switching rates, slow or fast whoop, swept frequency or a siren. A maximum continuous output of between 15dB(A) and 105dB(A) at 3 feet (1 meter) is available, but may be reduced by 15 db(A) using the internal volume control.
The Y05/ISA is rated as intrinsically safe and may be installed in a hazardous location when connected to a certified intrinsically safe circuit.
Operational Description
The Y05 Audible Alarm uses a microprocessor to generate the desired sound. Single or dual stage alarms can be generated using either two or three wire circuits. The diagram on page 3 shows a simplified block diagram of the sounder. It has two sets of terminals in parallel, each set numbered 1 to 4. One set allows connections from the safety barriers, the second set has been provided for the end-of-line resistors when required.
