i) Momentary Switch(es): The XR315 will power up when a switch is pressed once and
power down when a switch is pressed a second time. Connect the two wires from the
switch(es) to "up" and "common". Program the input for "Momentary".
j) Separate Up & Down Switches: The XR315 will power up when the UP switch is pressed
and power down when the DOWN switch is pressed. Connect the two wires from the UP
switch to "up" and "common", and the two wires from the DOWN switch to "down" and
"common". Program the input for "Separate Up & Down".
k) Center-Off Switch: The XR315 will power up when the switch is pressed to the UP
position and power down when the switch is pressed to the DOWN position. Connect the
wire from the UP terminal to "up", the wire from the DOWN terminal to "down", and the
wire from the COMMON terminal to "common". Program the input for "Separate Up &
Down".
l) Latching Switch: The XR315 will power up when the switch is closed and power down
when the switch is open. Connect the two wires from the switch to "up" and "common".
Program the input for "Latching".
Note: The front panel button will not operate with options a, b or f
12.2.2 Over-Ride Input
The XR315 has the option of adding an over-ride function for purposes such as providing fire
safety over-ride to force the system either on or off. An over-ride is initiated by applying a dc
voltage of 5-30V or by a sustained contact closure. The selection of dc voltage or contact closure
is accomplished during programming. This topic is covered fully in the programming section.
Connect the over-ride signal to the "over-ride" input and "common". In the case of a dc voltage,
connect the positive wire to "over-ride" and the negative wire to "common".
12.2.3 External LED Connections
The XR315 is able to drive external LEDs or other signaling devices through its 12V dc output
which can provide up to 40mA of current. External LEDs connected in this way will mimic the
red LED on the front panel. When connecting LEDs to the 12V output, a series resistor is
required. For example, many LEDs work well with 10mA of current, so a 1K resistor is usually a
good choice. If more than one LED is required, then use a separate series resistor for each LED.
In this example, four external LEDs could be powered at 10mA each from one XR315. If more
than four LEDs are required, it will be necessary to increase the series resistor so that the total
load is not more than 40mA.
Connect each LED anode to "12V dc output" through a resistor, and the cathodes to "common".
Program the 12V dc Output for "LED". This causes LEDs connected to the XR315 to flash while
the unit is powering up or powering down in the same manner as the front panel LED.
