Firstech Shock Sensor - Optional
For best results mount the shock sensor by zip tying it to the vehicle’s main ignition harness or other solid harness.
There is a small dial on the sensor that ranges from Off to 10. The higher the number on the dial the greater sensitivity
of impact. A small adjustment to the dial can make a significant difference in sensitivity for both 1st and 2nd stages.
Recommended dial settings for most vehicles is somewhere between 2 & 4.
Siren - Optional
The volume output of the siren can be increased 3 dB by cutting black wire loop located near the base of the siren. To
adjust duration time when the alarm has been triggered, change Option 2-07 – the system default is 30 seconds.
Thermistor (Temperature Sensor) Optional
Every 2 Way remote - Firstech system includes an optional thermistor, which must be plugged into the 2 pin port of the
control module for use. The use of the thermistor allows the 2 Way remote to display the vehicle’s interior temperature
on the remote LCD (Liquid Crystal Display) as well as permitting the vehicle to start with timed Hot or Cold starting;
see options 2-01, 2-02 and 2-03. IMPORTANT: New thermistor plugs are blue 2 pin connectors on the CM5 series but
old white plug thermistors will still work.
Setting Auxiliary Output
To set auxiliary outputs on the control module you must set these using the boot loader via your computer.
Set menu to Option 2-05 and 2-06 and set the options. You can only set specific time from 1 – 100 seconds on Aux 1.
Please see the Option Table for details.
Tach Sensing
Tach sensing for the FT-820 is done through the vehicle’s data connector or CAN network. There is no manual wire to
connect to the vehicle’s engine bay for a proper tachometer signal.
Reservation Mode for Manual Transmissions
To remote start a manual transmission vehicle, the system must first be set up in reservation mode. Reservation mode is
designed to prevent the vehicle from remote starting while the transmission is in gear.
Installation Requirements
1. The vehicle’s door triggers must be connected to the control module. Prior to making final connections, test the fac
-
tory door triggers to ensure that they are functioning properly.
2. The vehicle’s emergency/parking brake wire must be connected to the control module. The proper vehicle wire usu-
ally provides a negative (-) trigger while the emergency / parking brake is set.
3. The vehicle’s clutch must be momentarily bypassed while the remote start cranks the engine. This momentary
bypass simulates the clutch being depressed. For complete details on how to wire a momentary clutch bypass consult
your CompuTech program or contact our technical support department by calling 888-820-3690.
IMPORTANT:
Do not install a remote start in manual transmission vehicles with convertible / removable tops and
in user’s vehicles that leave their windows down. Firstech nor their authorized dealers will assume responsibility for
improper use or install.
