Often in the design of a control system the requirement to provide a “common” alarm signal to say drive an audible alarm or signal a BMS system is required. However, it is sometimes required that after an alarm input signal is received the output relay is cancelled, thus say silencing an audible even if the alarm input is still present, but also with an alarm contact still to remain to give silent indication. The YWA10 achieves this function.

The YWA10 is only available in 24VACDC input voltage. In all cases the input signals must be derived from the same source, with AC versions also derived from the same phase.

The integral electronics ensures that each input is electrically isolated from each other, thus preventing feedback from occurring between inputs.

YWA10, any input in then two separate output relays energise. One output relay (AA) can then be reset via a pulse to the cancel terminal “C”, even if the original input(s) is still present, the second relay (BB) will always remain energised so long as an alarm input is present. Another input in and the cancelled relay will energise again - and so on.

Voltage tolerance: ±15%

Operating temperature: -20°C to +65°C

Output contact: 5Amps/250VAC

Housing material: Polycarbonate, Auto extinguishable to UL 94 V-0

Terminal N: Common Neutral or with DC 0V

Terminal C: Cancel input (for DC +V signal required)

Terminals AA: Normally open alarm contact, closes on alarm, opens on reset

Terminals BB: Normally open alarm contact, closes on alarm

Terminals 1-10: Alarm signal inputs (for DC +V signals required)
