3.1 Inputs
3.1.1 Input 1 (Selectable Via DIP Switches)
Standard Input - (DIP switches S1 OFF, S2 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.
Pulse Counter - This mode configures the unit to count 12-volt pulses. This is not intended
•
for rapid repetitive pulses.
Timed Bell - (DIP switches S1 ON, S2 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.
Sampled Siren* - (DIP switches S1 ON, S2 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.
