To use the operator in any of the Failsafe wiring modes, or Timer To Close wiring modes (TS, T, FSTS), a LiftMaster self
monitoring safety device must be installed.
Recommended LiftMaster Self Monitoring Safety Devices:

NOTE:
1. External interlocks may be used with all functional modes.
2. Auxiliary devices are any devices that have only dry contacts. Examples are: photocell, loop detector, pneumatic or

3. Open override means that the door may be reversed while closing by activating an opening device without the need
to use the stop button first.

TYPE STATION
T 3 Button, 1 Button, 1 & 3 Button Radio Control
Function: Momentary contact to open, close, and stop, with open override and
Timer To Close. Every device that causes the door to open, except a
reversing device, activates the Timer To Close. Auxiliary controls can
be connected to open input to activate the Timer To Close. If the Timer
To Close has been activated, the open button and radio control can
recycle the timer. The stop button will deactivate the timer until the next
command input. The Timer to Close will function from the
programmable mid-stop with this wiring type. (NOTE: Requires
Optional self monitoring photo eyes to operate.)
FSTS Momentary button contact for open, close and stop. Radio controls
allowing open, close and stop. User set midstop. User set Timer To
Close. The single button station opens the door to the full open limit
bypassing the mid stop and activates the Timer To Close, putting the
operator in TS mode until the door reaches the down limit, or is
stopped in travel. At which time the operator enters the B2 mode.
