FO2 - 86° F/30° C: will activate the start sequence at the end of the time cycle (set by feature 2-06
option setting) if temperature is at or above this temperature.
FO3 - 95° F/35° C: will activate the start sequence at the end of the time cycle (set by feature 2-06
option setting) if temperature is at or above this temperature.
FO4 - 104° F/40° C (default) PROGRAMMABLE 20 ~ 65 [°C] / 68 ~ 150 [°F]: (using the OP500
programmer with software v.310 or newer that can be found at www.firstechdata.com) will activate the
start sequence at the end of the time cycle (set by feature 2-06 option setting) if temperature is at or above this
temperature.
2-10 Engine Sensing: This feature determines how the CM will monitor the state of the engine (running or not
running), release the starter output, and consider the vehicle running. We provide 4 options for engine
sensing methods
FO1 - Tachless Mode
–
(Automatic Transmission Vehicles Only)
Tachless sensing is an alternative engine sensing mode. It does not require a connection to the vehicle
other than the main ignition harness. Note: due to the delayed peak charging found with most late
model computer controlled alternators, this feature may not be reliable.
FO2 - Tach: This option uses a hard-wired input (yellow/black CN3 connector) or data signal from a
compatible interface module
to read the vehicles RPM’s
to release the starter during the remote start
process and determine that the engine is running.
FO3 - Alternator: This option uses the hardwired tach input (yellow/black CN4 gray connector) to read
the voltage output from the vehicles stator wire to release the starter during the remote start process and
determine that the engine is running. Note: with late model computer-controlled alternators, the peak
charging voltage mat not be reached for several seconds after the vehicle is running. This may make
this option inconsistent when the battery is low or very cold.
FO4 - No Connection Assumed running: Note: can only be used with automatic transmission.
(default to 3 seconds),This option provides a fixed starter output, and will then leave the rest of the
CM900 ignition and accessory outputs on and assuming the vehicle is running. Note: This is a good
option for (PTS) Push to Start applications and Hybrid vehicles (except manual transmission).
2-11 Advanced Tachless: This feature when used in conjunction with feature 2-10 option 1 will provide an
enhanced Tachless engine sensing mode.
FO1 - Off: (default)
FO2 - On: this option will enable the advanced algorithm. This option is better suited for late model
computer-controlled vehicles or older vehicles with poor battery conditions. Note: feature 2-10 must be
set to option 1 for it to work properly. If there is tach signal input to the CM900 either analog or data
interface module, this option will not operate consistently.
2-12 Crank Time: This feature allows the user to add or remove crank time to the selected option for feature
2-10 (engine sense).
FO1 - Standard: (default crank time no change).
FO2 - +200mS: To standard crank time of option selected on feature 2-10.
FO3 - +600mS: Adds 600 milliseconds to standard crank time of option selected on feature 2-10.
FO4 - (-)200mS: releases the starter output 200 Milliseconds earlier than standard crank time of option
selected on feature 2-10.
