Accessory manuals for most make and model accessories

can be found on the web at:

The accessory manuals you have or find at the above address may be

written to coincide with that manufacturers model of gate opener. To

determine correct terminals on your Estate Swing operator, use the

accessory terminal section of your Estate Swing manual. The following are

some common terms and abbreviations found in manuals:

Normally Open – abbr. N/O – Indicates a circuit that is left open during

normal operation of the gate operator. When a device closes this circuit it

signals the operator to perform a function. This circuit is the main circuit for

entry devices. (i.e. keypads, exit wands, push buttons, etc.)

Normally Closed – abbr. N/C – Indicates that in order for the gate opener

to be active this circuit must be closed. When a device opens this circuit it

stops the motion of the gate operator. This circuit is the main circuit for

safety devices. (i.e. photo eyes, safety loops, etc.)

Common – abbr. COM – This is the matching terminal for both Normally

Open and Normally Closed circuits to be connected to. Accessory wiring

that begins in a N/O or N/O terminal must have a wire that ends in a

Common terminal.

Ground – abbr. GND or GRD – Ground is sometimes also known as

negative. Common terminals are the same as Ground terminals. Ground

can also be the negative spade of the battery if it is being used in

association with positive voltage.

If a device has both a N/O and a N/C wire, both are never used at the

same time. Some devices can be used as either an opening device or a

safety device (i.e. gate crafters exit wand, NIR photo eye, etc.) If being

used as an opening device use the N/O and if being used as a safety

device use the N/C terminals.
