1
Locate box on interior of building within 100 tubing feet
of the door to be controlled.
Box must be in a clean,
dry, well ventilated place where temperatures do
not exceed 120°F or fall below 35°F.
2
Mount box to a structurally sound surface using
screws provided as shown on page 2 with air fittings
on left side as shown.
Do not mount box upside
down or on a horizontal plane.
3
Refer to instructions packed with actuators and
connect leads to terminals 5 through 10 as required.
4
Connect unpowered 120V AC input to terminals 3,
4, and ground screw. (Line side to ternimal 3, neutral
side to terminal 4 and ground wire to ground screw).
If door control is on a fire door, 120V AC input must
be interrupted by the fire alarm panel when in alarm.
When dry auxiliary fire alarm contacts are used,
remove shunt from terminals 1 and 2 and connect to
dry contacts of fire detector or alarm panel. Terminals
1 and 2 are in series with line side of 120V input.
5
Turn on power. Air valve will operate one cycle when
power is applied.
6
Air pressure output valve has been preset at factory.
If more air pressure is required to adequately open
doors, adjust regulator valves found inside control box.
7
Adjust time delay to keep air valve energized by
turning adjustment wheel on timer modules “A” & “B”
(CW to increase - CCW to decrease). The LED (light)
on the timer module indicates the valve is energized.
The time can be adjusted from 0-30 seconds. 10
seconds is a “normal” delay.
8
When using sequential operation, adjust dual timer
module “S” for desired delay between door operation.
(CW to increase delay; CCW to decrease delay). Top
timer delays “A” to “B” operation; the bottom timer
delays “B” to “A” operation.
9
Test actuators to ensure wiring and tubing are properly
connected.
