MS850 Installation Manual - Page 17
no chirps = ignition
1 chirp = door
2 chirps = shock sensor
3 chirps = trunk
When Audible Tamper Alert report is turned off, the siren will emit a long chirp on disarming
to indicate the system was triggered, but the zone indication will be from the status LED
only.
5. Door Unlock Pulse - Single/Double. Selects between a
single pulse or a double pulse
door unlock output.
On many late model Nissan vehicles, as well as some European makes, the factory door
locking system requires two pulses on the proper wire to unlock the vehicle’s doors.
Programming the system for Double Pulse Door Unlocking allow these systems to be
interfaced directly
without the use of relays or any additional circuitry.
6. Auto Rearm. When selected, the system will automatically rearm if no other activity is
detected within one minute of Remote Disarming.
One minute after Remote Disarming, the system will alert you with a 10 second series of
chirps, then arm. (If the Passive Door Locking feature is selected during the installation, the
system will also relock the doors.)
Any of the following will cancel Automatic System Rearming:
• Turn on the ignition.
• Activate Auxiliary Function.
• Open the Trunk or Hood.
Automatic System Rearming is independent of Passive Arming and only takes place if the
system was Armed (actively or passively) for at least 15 seconds and then Disarmed by the
Remote Transmitter.
7. Door Entry Delay with Passive Arming. When selected, the door input trigger will be
delayed for 15 seconds, allowing access to the emergency override switch. Only delays
when the system is arm passively.
8. White/yellow Wire Operation. Selects between operation of an auxilary remote function and
Dome Light operation for this output.
Aux. - Yellow/white wire will provide a negative output each time the Auxiliary Function
Button is pressed. The output will stay active for as long as the button is held.
Aux. w/ Trunk Bypass - When the Aux. function is used to activate a power trunk release,
the system will temporarily ignore the trunk trigger input and the sensor inputs when the
trunk is opened by the remote while the system is armed.
Dome Light Control - the system will turn on the vehicle’s dome light for 15 seconds each
time the system is disarmed and after the ignition key is turned off.
9. Passive Door Locking. Sets the system to automatically lock the doors during
Passive
Arming and Auto Rearming.
10. Transmitter Operation. Configures the system’s Remote Tranmitters to work in one of
three operating modes: Standard Mode, Convenience Mode, and Driver Door Priority Mode.
See Remote Transmitters - Transmitter Operating Modes.
