UNIT WIRING
Input 1 (Selectable Via DIP Switches)
A. Standard Input - (DIP switches S3 OFF, S4 OFF) This mode configures the
unit to be tripped from a DC voltage ranging from 9 V DC to 12 V DC or an open
collector.
B. Timed Bell - (DIP switches S3 ON, S4 OFF) This mode configures the unit to be
tripped from a DC voltage ranging from 9 V DC to 12 V DC. The unit reads a
pulsed voltage as a fire signal and a steady voltage as a burglary signal. It may
be necessary to place a 1K Ohm resistor in parallel to prevent false alarms when
using panels with supervisory voltage on the bell circuit. Some panels with
supervised bell circuits may require a 1K Ohm resistor in the circuit. Contact
Technical Support for further details.
C. Sampled Siren* - (DIP switches S3 ON, S4 ON) This mode configures the unit
to be tripped from a siren driver or a panel with a built in siren driver. The unit
reads a steady tone as a fire signal and a yelping tone as a burglary signal.
*NOTE: The input assumes that a speaker is connected to the panel. If you are
not using a speaker we recommend using a Timed Bell instead of Sample Siren.
This is an option on most panels.
Input 4 (DIP switch S8 ON) A trigger of INPUT 4 from high-to-low and back-to-
high causes the CDMAEZ to reset. The high-to-low-to-high must be held for
at-least 100 msec.
