Note 1
: The control inputs are powered with a weak internal pull up (5
volts at 0.2mA). The inputs are designed to be operated from voltage free
contacts (relays or switches) or switched voltage. If the switched voltage
method is used, the control voltages must not exceed 12V and a 1000 ohm
pull down resistor is required across the input.
Note 2
: The rated power is the combined output power of both the “Siren”
and “Strobe” outputs. The voltage which can be expected on this output is
the battery voltage. The combined maximum output current of both these
outputs is 2.5 Amps. Note that the maximum output power will drop as
battery voltage drops.
