OPTIONAL ACCESSORY WIRING
MASTER/SECOND SYSTEMS
NOTE:
The timer switch on the second circuit board must be OFF
at all times.
1. Connect 115Vac to each SW425 gate operator. Connect the
Master/Second wires (4) from the master circuit board to the
second circuit board (Figure 1). Any operator can be used as
either a master or a second. Accessories can be connected to
the master or second operator.
2. Switch the Auto Close Timer switch to the OFF position on the
second circuit board. The Auto Close Timer switch on the
master circuit board may be switched either ON, if the timer
function will be used, or OFF, if the timer function will not be
used, but the second timer must always be switched OFF.
LIGHT DELAY TIMER WIRING
If it is desired that the driveway illuminate when the gate is
activated, a light delay timer may be installed. The light delay timer
will switch power on to the light for two minutes, then shut power
back off. The timer relay is capable of switching up to 10 amps
which will handle most flood or spot lights available. A general
hook-up diagram for the light and timer is shown (Figure 2).
EXTENDED AUTO CLOSE TIMER WIRING
The standard auto close timer built into the circuit board can be
adjusted to between 0 and 45 seconds. Some installations may
require that the gate must stay open for more than 45 seconds
before it automatically closes. The extended auto close timer may
be hooked up as shown (Figure 3). This optional timer can be
adjusted to automatically close the gate after the gate has been
open between 1 and 100 minutes. The extended timer will add
time onto the auto close timer already on the board. For more
control, reduce the timer adjustment on the main control board to
zero seconds and make all adjustments with the extended auto
close timer knob.
WARNING ALARM WIRING
For added safety, a warning alarm may be installed in the gate
operator to give audible warning that the gate is in motion. This
will in some cases give extra time to get out of the way of the
moving gate. The warning alarm is an ear piercing 120 decibel,
dual tone, piezo siren that operates on 12Vdc. To install the
alarm, mount the siren next to the circuit board and connect the
positive wire to terminal 12 (12Vdc) (Figure 4). Connect the
negative wire to limit switch 1 NC or limit switch 2 NC for the
alarm to sound in the open or closed directions. Contact the
manufacturer for connecting the alarm to sound in both
directions. If the alarm is to loud, the sound may be partially
muffled by applying tape over the two holes where the sound
comes out.
