Stanley MA900 Features and Functions
Magic-Touch™ A feature that allows the door to be actuated by
a slight movement of the door.
Manual Operation If power is shut off, the door functions as a
manual door.
Lock Delay Delays the operation of the door 1/2 sec to allow a
lock to release.
Power Close In a building in which stack pressure exerts a force
that prevents the door from closing, the Power Close feature can
be actuated to help it to close.
Swing-Safe Technology The electronic safety control senses an
obstruction during the opening cycle of the door. The operator
immediately reverses the door direction, allowing time for the
obstruction or person to clear the swing path area of the door.
Adjustable Time Delay When it reaches the fully open position,
the door pauses for a specified time before closing. The time delay
is adjustable, and must be set to at least 5 seconds. The maximum
available adjustment is about 30 seconds.
Adjustable Opening Angle The angle of the door at the fully open
position can be set in the range of 90˚ to 120˚.
On/Off Switch When the switch is in the On position, power is
supplied to the operator. When the switch is in the Off position, the
MA900 works as a manual closer.
Mode Switch Controls Hold Open or Operating Mode
(Day or Night).
• Hold Open - When activated the door is moved and held
in the fully open position.
• Day and Night Operating Modes - In Day mode all features
are fully operational. In Night mode actuators (for example,
a push plate or an RF transmitter) are deactivated. If the
Magic-Touch™ feature has been turned on, it remains
active.
Sequential Operation This feature provides for sequenced oper-
ation of two units. For example, in a vestibule the opening of the
second unit can be delayed 1 to 30 sec after the opening of the first.
Easy Interface The MA900 can be easily interfaced with various
access control system components, including keypads, card
access, proximity, electric strikes and exit devices with electric
latch retraction.

cccccvestibule they must be connected to the timing and sequencing module per the instructions provided with the module.
4.) Momentary electric strikes: If using an electric strike that requires only a momentary contact to prevent overheating,
ccccca one-shot relay may be needed. Upon receiving an activating signal, this type of relay provides an open or closed
ccccccontact for an adjustable time interval. An example is Magnecraft part number TDRSRXP-24V.

Tune-In Procedures
Tuning-in is the process of adjusting the operating characteristics
of the Stanley MA900 — opening time, closing time, etc.
The door must operate in accordance with the ANSI
(American National Standards Institute) Standard for
Power Assist and Low Energy Power Operated Doors,
A156.19.
The tune-in procedures must be followed completely,
and in the order presented here, to make certain that
the door is in full compliance with the ANSI standard.
Check your local code requirements to assure com-
pliance in your area.
Cam Adjustments

Overall view of operator assembly, with callouts to cams
Back-Check Cam
The door opens at normal speed until it is almost fully open; then
back check is activated, and the door moves slowly to the fully
open position. The ANSI standard specifies that the back check
must not occur before the door is open at least 60˚. Normally the
back check occurs about 20˚ before the door reaches the fully
open position.
1. Power up. Test door operation by setting the mode switch to
Hold Open, or by using the external actuation device. Make
sure that back check occurs after the door is open at least
60˚, and at least 10˚ before the door is fully open. If it is in
compliance with the ANSI standard, go to Latch-Check Cam,
below. If it is not in compliance with the ANSI standard, go to
step 2.
2. Power down.
3. Using a 3/32” Allen wrench, loosen the set screw on the back-
check cam (top cam) (see Fig. 26).
4. Use the Allen wrench to rotate the back-check cam.
5. On a right-outswing or left-inswing door, rotate the cam count-
er clockwise (ccw) to increase, clockwise (cw) to decrease,
the back-check angle.
6. On a left-outswing or right-inswing door, rotate the cam cw to
increase, ccw to decrease, the back-check angle.
7. Use the 3/32” Allen wrench to tighten the Allen screw.
8. Power up.
9. Test door operation by setting the mode switch to Hold Open,
or by using an external actuation device. If necessary, power
down and readjust the cam.
Latch-Check Cam
The door closes at normal speed until it is almost fully closed; then
latch check is activated and the door moves slowly to the fully
closed position. The ANSI standard specifies that the latch check
must occur 10˚ before the door reaches the fully closed position.
1. Power down. Test door operation by moving the door to the
open position and releasing the door. Make sure that the latch
check occurs 10˚ before the door is fully closed. If it is in com-
pliance with the ANSI standard, go to Adjust Opening and
Closing Times, below. If it is not in compliance with the ANSI
standard, go to step 2.
2. Power down.
3. Using a 3/32” Allen wrench, loosen the set screw on the latch-
check cam (bottom cam) (see Fig. 26).
4. Use the Allen wrench to rotate the latch-check cam.
• On a outswing or inswing door, rotate the cam ccw to
increase, cw to decrease, the latch-check angle.
• On a left-outswing or right-inswing door, rotate the cam
clockwise to increase, counter clockwise to decrease the
latch-check angle.
5. Use the 3/32” Allen wrench to tighten the Allen screw.
6. Power up.
7. Test door operation by manually pushing the door open and
checking the position at which latch check occurs. If neces-
sary, power down and readjust the cam.
Do not wear rings, watches or loose clothing
while installing or servicing the door operator.
