The Child Check-Mate Safety System (CCMS) is made up of two main components. The first is the Main Alarm Unit (MAU), which is mounted at the front of the bus near the driver and comes with a separate "Wiring Harness". The second, is the Rear Vehicle Transmitter (RVT-Reset Button) that is mounted on the inside rear of the bus.
Note: Some RVT installations will require a "Conduit Kit".
Questions relating to the installation should be directed to Allan Lowe, VP Engineering, Child Check-Mate Systems Inc. ccms@childcheckmate.com or directly at 613-835-9828.
A) Installing the Front Master Alarm Unit
Location and Mounting: (back to top)
- Locate a convenient mounting area for the Master Alarm Unit within the main electrical panel at the front of the bus. Before securing the unit, check to ensure that its location is central enough so that it can be reached easily by the plug leading from the wire harness once all the wires have been connected.
- Secure the unit to the wall using the two-sided tape provided.
- Once mounted, screws may be applied to the holes located at each end of the Unit.
Connecting the wire harness for the Master Alarm Unit: (back to top)
- Before plugging into the Master Alarm Unit, connect wiring harness as follows;

 |
- Connect the YELLOW wire to ignition - 12 volts.
- Connect the RED wire to battery 12 volts. (Positive all the time)
- Connect the BLACK wire to a good ground connection.
- Find the horn relay of the bus and connect the GREEN wire to the ground side of the horn relay. NOTE: You may need to run extra (18 gauge) wire if the relay or ground wire is located under the steering column. If there is no horn relay, a relay must be installed. See insert.
- The brown wire is connected to the overhead lights and becomes live whenever the overhead lights are activated. Ensure that the brown wire "is not" connected to the master switch.
- Find the front warning buzzer of the bus. On this buzzer there are two wires - one wire runs to the rear door switch, the second wire becomes positive when ignition is turned on. Join the BLUE wire of the Child Check-mate system to the wire running to the rear door switch.
- Once the wire harness has been connected, simply plug it into the Master Alarm Unit.
- You are now ready to install the Rear Reset Button
B) Installing the Rear Vehicle Transmitter (RVT-Reset Button)
Location and Mounting: (back to top)
The RVT can be mounted two different ways depending upon whether the bus is "rear engine" or "conventional" rear door model.
Rear Engine Buses: (back to top)
On rear engine buses, the wires extend out of the "back" of the unit directly into the wall panel. The RVT is mounted above the window on the bus wall over the furthest rear seat on the driver's side of the bus. The RVT is connected to the furthest rear window or side door buzzer. The following steps describe the proper mounting procedures for rear engine buses:
- Drill a 23/64th-inch hole at desired location over the rear seat.
- Insert plastic grommet, (supplied) into drilled hole.
- Loosen panels required to run the two wires to the closest emergency buzzer. This could be either the rear emergency window buzzer or the side emergency door buzzer.
- Feed the two wires out the "back" of the RVT and through the pre drilled hole and secure it to the panel with the top screw (supplied). IMPORTANT: The lock washer provided MUST be installed between the bus body and the Rear Vehicle Transmitter to ensure a good ground.
- Place the small plug (supplied) over the two remaining holes at the bottom of the Rear Vehicle Transmitter secure to panel.
- Refer to "connecting the RVT wires" on following page.
Conventional Buses: (back to top)
For installation on conventional bus models, the wires can extend out of the back of the RVT and fished down the back wall of the bus into the rear door buzzer housing. Alternatively, the wires can extend out of the "bottom" of the unit using an optional "Conduit Kit" Model RVT-2Wc available from Child check-Mate. The RVT is mounted at the top right of the rear emergency doorframe, and is connected to the rear door buzzer thorough the conduit. The following describes the proper mounting procedures when installing on a conventional bus:
- Prepare the Buzzer housing as shown below if using a conduit mount, or; drill a hole and fish wires following the installation procedures outlined above for Rear Engine Models.
- With the two wires running out the "bottom" of the RVT, mount the unit to the doorframe with the three self-tapping screws (supplied).
 REMEMBER:
The lock washer supplied must be installed between the bus panel and the Rear Vehicle Transmitter to ensure a good ground.
- Measure the desired length of the conduit to be cut. Allow for any bends necessary then add ½ of an inch for the conduit to be inserted into the buzzer housing and the RVT.
- Once the conduit has been cut, feed the two wires through the conduit and push the conduit just inside the Rear Vehicle Transmitter about 1/8th of an inch. Do not force the conduit too far into the RVT
- Bend the conduit along the path chosen and secure the conduit to the bus with the "P" clips and screws (supplied). Because of the thickness of the doorframe, it will be necessary to pre drill the screw holes.
- Refer to "connecting the RVT wires" on following page.
The tools needed for the cut away portion of the buzzer housing will vary, depending on which material the housing is made from, i.e. plastic or metal. Drill a hole large enough for the conduit on the top of the housing. The hole should be close to the middle of the housing, tight against the mounting flange of the housing. See area marked in red on housing diagram. Cut away the mounting flange so it will meet up with both sides of the hole drilled as shown by a dotted line in the housing diagram. This cut out will allow removal of the buzzer housing in the future. While not disturbing the conduit.
Connecting the RVT wires: (back to top)
- GROUND SIDE OF BUZZER - BLUE WIRE -
- 12 VOLT IGNITION OF BUZZER - RED WIRE -
- The Rear Vehicle Transmitter is to be wired to the closest emergency buzzer / switch assembly. Typically the rear emergency door or window.
- View the following diagrams to determine which switch is being used.
- Connect the BLUE wire to the wire running to the front buzzer.
- Connect the RED wire to the 12 volt side of the buzzer.
Operation Check List: (back to top)
- Start the bus; turn on the master switch and then, the yellow pre-warning overhead flashing lights only (DO NOT ACTIVATE THE RED OVERHEAD FLASHERS at this time). Turn off the lights and the bus. The Child Check-Mate System alarm should not sound. If the system alarm sounds, re-check your brown wire location.
- With the front door closed, start the bus, turn the master switch on. Open the front door, the overhead lights should be flashing at this point. Note: In California, insert this step! "With the Red Lights still flashing, turn the ignition off and remove the key. The system alarm should not sound. Turn ignition back on." Close the front door, the overhead lights will stop flashing. Turn the ignition off. The system alarm (a high pitched beeping) should begin to sound. Turn the ignition back "on" or to the "accessory" position; the alarm should be silenced in either position. Return to the rear of the bus and depress the reset button and hold for at least one second. You will hear a deactivation signal (a rapid chirping sound). The system has now been deactivated and the key can be removed from the ignition.
- With the front door closed, start the bus, turn the master switch on. Open the front door, the overhead lights should be flashing at this point. Close the front door, the overhead lights will stop flashing. With the bus still running, return to the rear of the bus and depress the reset button once again until you hear the deactivation signal. Turn ignition off, the alarm should not sound and the key can be removed.
- Close the front door, start the bus, turn the master switch on. Open the front door, the overhead lights should be flashing at this point. Close the front door, the overhead lights will stop flashing. Turn the bus off and allow the alarm to continue to sound. After one minute the Vehicle's horn should pulse "on" and "off" at one-second intervals. Turn the ignition back "on" or to the "accessory" position, to silence the alarm. Return to the rear of the bus and depress the reset button until you hear the deactivation signal. The system has now been deactivated and the key can be removed from the ignition.
- Apply sticker to inside front of vehicle above entrance door.
