Min recall, No recall options.
• Detector diagnostics with “max fail recall”
• Detector memory on or off
• Vehicle Recall modes; extension, maximum, soft,
or ped recall.

Pedestrian Features
• Flashing Don’t Walk through Ped Clear
• Flashing Walk
• Conditional ped service
• Flashing Don’t Walk through Yellow.
• Exclusive ped
• Dual Enhanced ped--barrier phase walk (e.g. ph 2)
waits for other ring walk (e.g. ph 6) if it starts early.
• Overlapping peds
• “Not ped” overlaps (O/L inhibited when selected
ped active, often used for right turn O/L’s)
• Walk Rest Modifier (WRM)
• Alternate ped timing by time clock (TOD)
Reporting Features
• Calls up to 2 phone numbers
• Scheduled time of day call-ins
• Prioritized messages (alarms)
• Detector volume logging
• MOE’s (Measure of Effectiveness) with Computed
speed and true speed, green utilization, volume,
occupancy and more.
• User defined messages
• Conflict monitor (MMU) messages
Pre-emption Features
• 6 high and low priority pre-empt inputs
• Assignable priorities
• Special Intervals
• Coordination during pre-emption
• Per overlap Inhibits during pre-emption
• Memory on/off
• Flash override
• Delay before pre-emption
• Omit non pre-empt phases and all peds during “last
x” seconds of delay
• Minimum re-service
• Priority return option to return to interrupted phase(s)
• Hold only pre-emption
• Flashing Don’t Walk through yellow during pre-
emption.
Transit Priority General Features
• 6 TP inputs for “soft” form of prioritized service to
transit vehicles.
• TP phases can extend settable amount past normal
force off or max.
• Non-TP phases can be shortened to get to TP phase
• Unit offset seeks to compensate for TP phase
extended timing.
• Control timing adjustment provided for customized
control
Time Clock Features
With an internal clock standard in all units, the LMD can
operate in response to time of day commands based on
a yearly program. This function can be used to imp-
lement various modes of operation such as night time
flash, and in conjunction with other controllers, wireless
time based coordination. In this mode, each controller
time clock simultaneously issues coordination
commands.
The time clock battery back-up feature allows the clock
to continue to keep time without power supplied, so there
is no need to reprogram, or re-setup the time clock after
power failure.
