    AUTRONICA KRC-1
    Alarm indication unit
    7225-026.0005

    The alarm unit consists of two seperate channels, A and B. Each channel has a hybrid tick film circuit, KRU-1, as a main element. The KRU-1 element is supplied from a 24 V d.c voltage (19V to 32 V d.c.) and a flashing signal. The input signal is fed from a normally closed alarm  contact. When the alarm contact is opened, and a time delay of 0,5 sec. is passed, alarm condtion is established. The acknowledge input is normally low. When an alarm is acknowledged, the input become high (+ 15 V d.c).
