    Mallory Pulsing Piezo Mini Alarm
    Audio Indicator
    Combined shipping provided on
    multiple purchases.
    Mallory Alarm Specs:
    Sound Level: 85 db
    Operating Voltage: 4 to 24V DC
    The alarm is not overly loud, yet
    it is still loud enough to be heard
    above most ambient noise in an
    adjacent room through an open
    doorway.
    As with all alarms that have
    self-contained electronics, proper
    polarity must be observed when
    connecting to a voltage source.
    The positive DC Supply voltage
    line connects to the side with the
    "+" symbol on the top of the alarm.
    Connecting with the polarity
    reversed will damage the alarm.
    Note:
    Since this is just an alarm, it does not
    include a triggering mechanism,  power
    supply, or have provisions for an internal
    battery.
    Because this alarm cycles ON and OFF
    Repeatedly, Battery Life (if run from a
    battery) is Longer than with Constant
    Sounding Alarms. A Pulsing Alarm is
    also a more distinctive and pleasing
    sound, and is more recognizable in a
    noisy environment.
    Features and Specs:
    Totally self contained electronic driver,
    just connect it to a 4 to 24VDC Power
    Source. Two Pins on bottom for
    mounting on Printed Circuit Boards.
    Size:
    24mm x 14mm (15/16" x 9/16")
    (excluding bottom pins).
    All Alarms Are Tested Before Shipping!
    Pulse Rate and dbs of sound produced
    are both somewhat related to the supply
    voltage used. Higher DC voltages will
    produce a louder sound. This is governed
    by the Laws of Physics and applies to all
    alarms made, not just this one.
    This alarm is not intended for use as an
    extension on home security alarms.
