50FY Series
Step 3 - Wire sensors to logic amplifier as
follows:
• Old component versions (amplifier, FYQLA-140R-
1 and sensor, 50FY40) cannot be ordered.
However, for maintenance purposes, the new
components (amplifier, FYQLA-140R-3 and
sensor, 50FY41) may be used in an old
installation (see installation warning).
• The 52FY30 magnet actuators will work with
50FY41 sensors, however, the sensing distance
will increase.
a. 50FY41 sensor (new) with FYQLA1-140R-3
amplifier (new)
• Connect each sensor (see Wiring Diagram) via its
four leads as a set to the logic amplifier as
follows:
FYQLA1-140R-3 (new)
R (positive)
W (normally open)
B (negative)
O (normally closed)
• To secure power and sensor leads, torque
connector screws 0,56 Nm (5.0 in.-lb.).
WIRING DIAGRAM
• If less than six sensors are connected to the logic
amplifier, install two 22 K Ω resistors across each
unused logic amplifier terminal set as follows:
Logic Amplifier Terminals
R - W
B - O
*The resistors are necessary for the proper operation
of the logic amplifier. Ten 22 K Ω resistors are
supplied with each 50FY Series system.

IMPROPER INSTALLATION
• This product is designed to conform to the
technical requirements of EN954 Category III and
ANSI B11.19-1990. To ensure compliance with
these requirements, 50FY41 sensors MUST be
used with the FYQLA1-140R-3 logic amplifier.
• Strictly adhere to all installation instructions.
Failure to comply with these instructions could
result in death or serious injury.
b. 50FY41 sensor (new) with FYQLA1-140R-1
amplifier (old)
• Cut and remove the ORANGE sensor leadwire.
• Connect the RED, WHITE and BLACK sensor
leadwires to the logic amplifier terminals as
follows:
FYQLA1-140R-1 (old)
R (positive)
W (normally open)
B (negative)
• To secure power and sensor leads, torque
connector screws 0,56 Nm (5.0 in.-lb.).
c. 50FY40 sensor (old) with FYQLA1-140R-3
amplifier (new)
• Connect the RED, WHITE and BLACK sensor
leadwires to the logic amplifier as follows:
FYQLA1-140R-3 (new)
R (positive)
W (normally open)
B (negative)
O (normally closed)
• Install one 22 KΩ resistor between the BLACK
and ORANGE logic amplifier terminals.
• To secure power and sensor leads, torque
connector screws 0,56 Nm (5.0 in.-lb.).
Special instructions related to 50FY40 sensors
used with FYQLA1-140R-3 amplifier
If the door is open more than one second and
power to the amplifier is ON, the ATTENTION
INDICATOR LED will flash. To return to a green
condition, close the door(s), shut amplifier power
OFF and wait until the ATTENTION INDICATOR
LED is completely OFF, then turn the amplifier
power ON (power on reset).
