Output Circuits Installation
There are four (4) Output circuits provided on the VFR-500, each rated 3.0 amps continuous at 24VDC. The Output circuits may
be configured for Class A or Class B. Class A wiring requires a Class A expansion board (CA-4064). Outputs may be programmed
to provide steady (constant) voltage, a cadence pattern, releasing service or synchronized strobes. Full synchronization is
maintained system-wide. The Outputs may be programmed as silenceable or non-silenceable.
An Output can be programmed for continiuous power while the panel is not in an Alarm condition, such as required for energizing
a Door Holder. The Output is considered a special application type, with a maximum output current of 3A.
Output Wiring Characteristics

Note: Type of Output is selectable, and may be configured for strobe synchronization with Gentex®, AMSECO®,
Wheelock®, or System Sensor®. Refer to the listing of compatible devices located in the "Output Compatibility Document",
Potter #5403592, for this information.
Output Maximum Wiring Impedance Formula
The maximum impedance is a function of the load placed on the circuit. To calculate the maximum line current impedance, use
the following formula:
(Alarm Current of Notification Appliance) x (Wire Resistance) < 3.0 Volts

Notes:
1. The Potter part number for the listed end of line assembly is #3005013 EOL Resistor Assembly.
Note: When a NAC is used as a releasing circuit, a Potter End of Line Diode (EOLD) assembly must be installed. The
EOLD is Potter part number 3005012 and must be installed in accordance with the installation manual
2. The panel has ground fault detection on the Output circuits. The impedance to ground for ground fault detection is 0
ohms.
