INPUTS
All inputs are specially treated to accept either a voltage (up to 24 Vdc), or a closure to
ground, which may be provided by switches, relays, or logic outputs. The inputs are
active low.
See the manual section 8 (Detailed Menu Reference) for details on using the panic dial
HOT TIP!
With system firmware versions 2.66 or later inputs 0-3 can
each be used as multiple panic dial inputs by setting Panic
Dial to “1-4” in the utility menu. Prior to this version there is a
single panic dial input using input 0.
DEEP TECH NOTE!
The Zephyr’s “universal” logic input circuit can be used with
switch or relay closures, voltage levels up to 24 Vdc, or logic
outputs – either “totem-pole” or open-collector.
