Connections From Device To The Operator - Chamberlain LM21AFCB Owner's Manual

CONNECTIONS FROM DEVICE TO THE OPERATOR

NOTE: For low voltage wiring #18 AWG is recommended.
OPERATOR CONNECTIONS
1. Connect terminals 11 and 12 from the release device to the
transformer secondary in the door operator. The required
voltage should be 24-30Vac.
NOTE: This connection must be made in order to avoid a
mechanical release in alarm conditions when the door is not
closed (Figure 2).
2. Connect release device to auxiliary limit switches on the
operator. These are required and must be provided by the
door operator manufacturer.
Auxiliary Closed Limit Switch (Figure 1):
Connect a wire from the common and N/O of the auxiliary limit
switch to terminals 13 and 14 on the release device. This input
will not allow a mechanical release if the auxiliary close limit is
activated. This circuit also turns off annunciators when the
auxiliary close limit is activated.

To prevent DAMAGE to the circuit board, auxiliary limit switches
MUST be provided as dry contacts and may not be used in
conjunction with the simultaneous switching of a motor control
or ANY other voltage through the same contacts. Connections of
this type will result in immediate damage to the release device.
Auxiliary Open Limit Switch (Figure 1):
Connect a wire from the common and N/O of the auxiliary limit
switch to terminals 14 and 15 on the release device. A
connection to an auxiliary up limit switch is required for
3-cycle obstruction count feature. Adjust the auxiliary open
limit to activate just before the operators open limit is activated.
AVERTISSEMENT
3. Connect wires from terminals 7, 8, 9, and 10 to the door
operator terminals that are used for 3-button station (for use
with N/O 'Close' switch, N/O 'Open' switch and N/C 'Stop'
switch). The close relay output latches to initiate a door closure
through the operator after the factory set delay.
