FDO Revision Comparison
Introduction
The proposed revision to the Fire Door operator line has been designed to be functionally identical to the previous revision.
Opening, closing, stopping, reversing and controlled descent functions are all equivalent to the functions present in the previous
revision.
All fire door functionality remains identical to previous revisions. Controlled descent retains the same control and load range as
the previous revision. All DIP switch selected delays and features remain unchanged.
However, it has been determined that changes to the battery testing routine would help make the device a more robust machine. The
proposed code will test the batteries more frequently to a lesser extent that the previous revision. This change helps to exercise the
batteries and extends their expected operating life. Additionally, battery presence is monitored much closer to ensure that the
batteries are properly connected in the operator.
Below is a feature comparison between previous and proposed revisions of an FDO B.

Battery Voltage Measuring
The battery voltage can be measured by measuring the DC voltage between J13 (+) and J14 (-) on the LMPLC board. The quick
connect inside the operator is not a “battery disconnect” but now a power disconnect and cannot be used to monitor battery
voltage at any time. Circuits from the secondary of the transformer in addition to the battery are now electrically opened when the
connector is disengaged.
Battery and charge voltage can be monitored separately while the operator is powered by removing the red (battery +) wire from J13
on the LMPLC board. The battery voltage is then available to measure between the red wire (+) and J14 (-). The charge voltage
may be measured between J13(+) and J14(-).
Advanced Feature Set Control Details
The Key Test input on the LMPLC board may be used to access undocumented features in Fire Door uses. The primary use of this
input is to place the operator in a test mode. Setting this mode is achieved by continuously holding this input for more than 6
seconds. The new features accessible by multiple momentary pulses to this input. All tests and controls are activated 10 seconds
after the last input. Additionally, the Forced Load Test may be initiated by holding the Open and Close buttons simultaneously for
5 seconds until a beep is heard.
The functions are entered when the operator is at rest in a non-alarm condition by providing momentary pulses to the Key Test
input. The test will be exited after completed or in the event that any input (Open, Close, Stop, Alarm, or Key Test) should be
received.
It is important to remember that these are undocumented features meant for technical support experienced technicians only. Battery
test will usually occur as an automated function requiring no user interaction. Additionally, code revision is maintained in the
factory and should not become an issue to be tested by the customer.

Battery Test Description
The proposed battery testing will provide improvements to the test in duration, frequency, failure definition, and safety.
1.
Duration
The proposed battery load test has duration of 5 minutes (1 minutes for FDCL) at a 1 amp current draw. The load is
created by placing the battery voltage across a 25 Ohm resistor. A one hour load test is adequate to ensure that the power
remaining in the batteries is sufficient to handle an emergency condition without requiring an excessively high level.
Additionally, a battery presence test will be conducted hourly to check that the batteries are present in the circuit. The
battery presence test has duration of 10 seconds.
2.
Test Frequency
The battery load test occurs only once every 24 hours for v400 or once every 7 days for v500. The test will not occur
within 12 hours of a power outage or an aborted test due to user input. The battery presence test will occur once every

hour. The battery load test can be forced by holding the Open and Close buttons continuously for 5 seconds while the door
is not in motion. This provides a means of provoking a full test at the request of technical support.
3.
Failure Definition
A failure is defined as a drop below the cutoff level of 22.1 VDC for 50 ms time. This ensures that only the DC voltage of
the battery dropping below the cutoff level leads to a test failure.
4.
Safety
Safety is improved by defining 3 possible battery test failures: a Severe Failure, Major Failure, and a Warning Failure.
a. Severe Failure. This failure mode occurs when the system determines that less than 10 seconds of battery backup
is available. The batteries are either not connected or are severely damaged. Notification will occur as a 1 second
on 1 second off pulse train. The batteries must be connected or replaced immediately in order to ensure a safe
system.
b. Major Failure. This failure mode occurs when the system determines that the batteries hold between 10 seconds
and 15 minutes of capacity for the v400 code or any time within the 5 minute test for v500 code. The on-board
sounder will begin notification immediately at 3 seconds per minute. The batteries will be retested every 24 hours
for v400 or every 168 hours for v500. The controller will attempt to close the door after 45 days of notification
and test failures (FDOB & FDC only).
c. Warning Failure. V400 Only! This failure mode occurs when the system determines that the batteries hold
between 15 and 60 minutes of capacity. The on-board sounder will only begin notification after 3 consecutive
tests spaced at 12 hour intervals fail in this mode. After 3 failures the controller enters the Major Failure mode as
noted above.

Firmware Revision Interrogation Description
The revision interrogation can be used by Chamberlain employees to confirm the version of code present in the MCU in testing new
products as well as RGA’s. The function is entered when the operator is at rest in a non-alarm condition by providing 7 momentary
pulses to the Key Test input. The test will be exited after completed or in the event that any input (Open, Close, Stop, Alarm, or
Key Test) should be received.
The function provides information in the following order: Operator Type, Major Revision, Minor Revision. The data is output in a
series of 1 second pulses from the onboard sounder. There is a 3 second delay between each piece of information. Nationally, there
information is ended by a single beep. The tables below provide the interpretation of the audible pulses.

Example of Revision Interrogation
A technician would like to verify the code revision in an FDO B. He provides a series of 7 momentary inputs to the Key Test
input. Approximately 10 seconds after the final input the operator begins to beep. He hears the following:
ƒ 2 one-second beeps
ƒ Three second of silence.
ƒ 5 one-second beeps.
ƒ Six seconds of silence
ƒ 1 one-second beep.
This translates into:

Operator Type = 2
5 one-second beeps.
Major Code Revision = 5
Six seconds of silence
Minor Code Revision = 0
1 one-second beep

The MCU has been programmed for a FDO B with code revision 500.

Battery and Code Replacement Kit (K29-FDOB-350 and K29-FDC-350)
In addition to the new version of operators, a kit containing updated firmware and new batteries is also being offered for use in
FDOB and FDC operators that are experiencing battery management issues. The kit consists of 2 batteries, a v350 microcontroller,
a chip puller and instructions.
Kit K29-FDOB-350 can be used in FDOB with v300 code. The battery management is updated but output power remains at 12
VDC.
Kit K29-FDC-350 can be used in FDC operators with v102 or newer code. The battery management is updated but output power
remains at 12 VDC.
These kits should be used in situation where an operator is experiencing battery problems. “…the thing starts beeping every
month… I reset it and 30-days later it starts again…” The kit contains new (date code inspected), load-tested batteries and a
microcontroller with updated battery management firmware.
