A New Solution for You...
A Replacement for CRS CR2 A/B
1.0 Introduction
The Bus-Scan CR2 is a specialized version of our traditional BS 300 series of Child
Reminder Systems. It is intended to provide a generalized replacement for the now-defunct
CRS CR2 A/B systems that were manufactured by one of our competitors. Even though it is
not meant to be an exact recreation of that product, it fulfills these criteria:
● It is plug & play, with a totally-compatible connector for direct substitution, and uses
the wiring from your existing CRS CR2 A/B installation. It is meant to plug into your
existing harnesses, and presumes your existing, working wiring.
● We also offer a wire harness, remote LED and remote disarm switch for new
installations.
● It relies on your door sensors to 'captivate' drivers until the unit has been properly
disarmed.
● The system will automatically arm after the ignition has been on for 10 minutes with
the doors closed (field-trip mode).
● If a driver fails to disarm the system and attempts to exit the bus, the horn will be
activated.
● To reset an alarm, the driver must recycle the ignition then complete the inspection
properly.
● We expect to add more features as we go—we listen to our customers!
● NOTE 1: The mounting centers of the Bus-Scan (4.1”) differ slightly from the CRS
system (approx. 4.2”).
● NOTE 2: Our CR2 replacement requires direct wiring to a push button that feeds a
Ground level for disarming. If your existing system uses the vehicle’s door buzzer
circuit and diodes, then you will need to provide a simple push button switch (we can
provide one, if you like – Order Num: 103547). It was never a good practice for the
original CR2 to use the vehicle buzzer wiring and diodes for disarming, and as a matter
of proper engineering, we chose not to perpetuate it.
1.1 The Purpose
This prototype represents our effort to fill the need and vacuum that was created when
CRS
CRS
went out of business, and their products became extinct.
2.0 Just so you know...
When it comes to Child Reminders, we have been around longer than anyone else—including
CRS. We were founded in 1988, and created the Bus-Scan® Child Reminder in 1995, about
10 months before CRS. We offer both hard-wired and our
exclusive
exclusive wireless models for
quick and easy installation. These models offer some great features, so please check them
out at: http://www.roboticstech.com/busscan/
We provide the best selection of Child Reminder types and models to fit
every requirement.
Here are feature comparisons between the Bus-Scan
®
CR2 and the CRS CR2 A/B:
Function
Bus-Scan
®
CR2
CRS CR2 A/
B
Ignition ON (Yellow +12V) Prepares the system for operation. YES YES
Arming Signal (Orange +12V) Arms the system OR... YES YES
System will automatically ARM after 10 minutes w/door(s) closed. YES YES
System has 2 door-sensing inputs: One for +12V / One for 0V (Gnd) YES YES
If either the White or Blk/Gry Wire is Grounded (0V), the system will
DISARM, and the interior lights will flash twice to confirm.
YES YES
If Exit Courtesy Lights are on, they can be interrupted by turning
the Ignition ON, so that the system is immediately ready for
operation.
YES NO
If the system has been ARMED, then the Ignition is turned off, a
reminder tone will sound, indicating that the vehicle must be
checked & disarmed. Also, the dome lights will be activated.
YES YES
Ignition must be in the OFF position to disarm system. YES YES
If any door is opened during the REMINDER state, the horn will
ALARM— ½ second on / ½ second off intervals until system is
disarmed.
YES YES
Ignored Horn Fail-safe operation: An ignored Horn alarm will cease
sounding after 5 minutes, to save battery power and horn function.
YES NO
If the system is in an ALARM state, the only way to stop the alarm
is to recycle the ignition and start the DISARM/INSPECTION
sequence over. The system will not permit an exit without alarm
until the proper DISARM SEQUENCE has been performed.
YES YES
Upon DISARM, the interior lights will remain ON for a period of 60
seconds, for help in exiting the vehicle (Exit Courtesy Lights).
YES YES
Entry Courtesy Lights will be activated for 60 seconds upon first
entry (door open, if closed / door closed, if open). Activating
Ignition will cancel the lights.
YES NO
If Ignition is ON and a door is opened, Passenger Courtesy Lights
will be activated to help guide passengers on/off the vehicle. The
lights will be immediately turned OFF upon door closing.
YES NO
The Warning Beeper is built-in, so no additional wiring is required. YES NO
Dual-row, 6-position Interface Connector for Power & Signals YES YES
Single-row 2-position Interface Connector for Remote LED YES YES
NOTE: We have been told that the main connector in the CRS CR2 A/B was too accessible, and
was being disconnected by some drivers. We have purposely recessed the connector slightly, to
make that less likely. Please let us know if that helps.
More features have been created for the Bus-Scan® CR2. See the next page for
details.
New CR2 Features
3-Position DIP Switch on Back of Unit
1. Timed Auto-arming (field-trip mode). In addition to arming the Bus-Scan CR2
by an input signal (8-way flashers, stop sign, etc.), you can choose to have the
system automatically arm after the ignition has been on for 10 minutes, with both
doors closed. Enable by sliding Switch 1 of the 3-position DIP switch to the 'ON'
position.
2. Timed Alarm Mode Adds a timeout alarm to the usual “Door Opened Without
Disarming” mode. Sliding Switch 2 to the 'ON' position enforces a time limit of 60
seconds for the driver to press the “Disarm” button. Therefore, the system must
be disarmed before opening a door AND within 60 seconds.
3. Diagnostic Mode This is used for factory testing, but can be used during
installation, to speed up the process. There are many timed functions in the CR2,
including auto-arming, light delays, etc. Sliding Switch 3 to the 'ON' position will
“speed up the clock” to move through those delays very quickly—so that you can
confirm that everything is working properly. For example, the usual Auto-arm of
10 minutes occurs in only 10 seconds. If you use this special Diagnostic Mode,
make sure to return Switch 3 to the 'OFF' position when you are finished.
Otherwise, the system will not function properly.
