feature descriptions
1 ACTIVE/PASSIVE ARMING:
When active arming is selected, the system will only arm when the transmitter is
used. When set to passive arming, the system will arm automatically 30 seconds after the last door is closed.
Passive arming is indicated by the rapid flashing of the LED when the last protected entry point is closed.
2 CONFIRMATION CHIRPS ON/OFF:
This feature controls the chirps that confirm the arming and disarming of
the system.
3 NO FEATURE
4 NO FEATURE
5 NO FEATURE
6 NO FEATURE
7 CODE HOPPING ON/OFF:
This system features Code Hopping as an option. Code Hopping is a feature that uses
a mathematical formula to change the system’s code each time the transmitter and receiver communicate. This
makes the group of bits or "word" from the transmitter very long. The longer the word is, the easier it is to block
its transmission to the unit. Disabling the Code Hopping feature lets the receiver ignore the Code Hopping part
of the transmitted word. As a result, the unit may have better range with Code Hopping off.
bypassing sensor inputs
There are times when you need to temporarily bypass all sensor inputs to the unit, such as when remote starting
the vehicle. Anytime an auxiliary channel output is used, all inputs are bypassed for 5 seconds. During the
5-second bypass period, ground can be supplied to the H1/6 Blue wire without triggering the unit. When the
5-second bypass period ends, if the unit sees ground on the H1/6 Blue wire, all trigger inputs except the door
trigger input will remain bypassed until 5 seconds after ground is removed from the BLUE wire. This can be done
using the status output of a 551T remote start unit as shown below:
