DO NOT INSTALL ANY SIMPLEX PRODUCT THAT APPEARS
DAMAGED. Upon unpacking your Simplex product, inspect the contents of the
carton for shipping damage. If damage is apparent, immediately file a claim
with the carrier and notify Simplex.
TrueAlarmPhotoelectric Smoke Detectors output diagnostic data encoded in
each visible LED pulse. The encoded data provides a present status indication
relevant to testing and inspection. The 4098-9839 Data Reader hand-held test
unit, is used to read, display, store, and download diagnostic data. The data
reader is battery powered, lightweight, and easy to read and interpret. It is
capable of storing test data for downloading to the Test and Inspection
Reporting System. Memory is non-volatile, allowing the reader to be powered
down without losing data. The reader decodes a detector’s diagnostic data and
provides immediate notification if the detector is outside its calibration limit.
The reader also has the capability to detect and indicate low voltage of its 9V
battery.
WARNING: Do not depress all push buttons on the data reader
simultaneously, this can clear the memory.
Power is applied via an ON/OFF switch. When powered ON, or by pressing the
SCAN button, the reader goes into scan mode, indicated by an illuminated red
LED. Point the reader to the appropriate detector’s LED and bring it to within
12-inches of the detector. When a valid reading is made, the green LED is
illuminated. When the diagnostic data contains a trouble message the red LED
remains illuminated, otherwise only the green LED is illuminated.
To scan detectors that are located in inaccessible areas, attach the pole mounting
bracket (provided) to the reader. With the bracket mounted to the reader it can
be attached to a testing pole. See Figure 2 for mounting instructions.
Note: Refer to Table 4 for a description of trouble flags and other diagnostic
data.
Table 1. Status Descriptions for LED Lights
A three-digit integer number is displayed to indicate the memory position that is
available for the next storage event. When a valid reading is made, and the
green LED is ON, the data can be stored into non-volatile memory for later off-
line downloading. To store the data, press the STORE button and hold it down
for approximately two seconds until the green LED turns OFF and the memory
counter increments to the next number. To increment the memory counter
without a valid reading, hold the STORE button down for approximately two
seconds until the counter increments to the next number. This loads the memory
position with all zeros.

When finished with scanning and storing, or if the limit of the memory is
reached, the data in the non-volatile memory can be downloaded through the
serial port located on the right side of the data reader. A serial cable must
connect the reader to a computer with upload capabilities. The data is
transferred by depressing the D/L button. If the reader is holding a valid
reading, and the green LED is lit, hold down the D/L button for approximately
two seconds. This is to protect against inadvertent clearing of the last reading if
it has not been stored.
To clear the non-volatile memory, power down the data reader then, while
pressing both the STORE and D/L buttons, power up the reader. Hold down
both buttons until the display indicates “#001” on the memory counter. This
procedure takes several seconds.
The display is a Liquid Crystal Display with two rows of 16 characters.
Examples of the display are shown below in Figure 1. When a valid reading is
made, the diagnostic data Hex code is first displayed. Next “XX%ALM” is
shown, where XX% is the percent to alarm of the last sample, then “#YYY”
where YYY is the next available non-volatile memory location. When the
battery runs low, a low battery message is displayed.

The data reader displays a message (similar to the one shown in Figure 3) when
a compatible detector is scanned and a valid reading is made. The data shown as
“20%ALM” represents the value of the last smoke measurement in terms of
“percent to alarm”. For example, if the last measurement returned a value above
the factory set “Clean Air Value” and is half way to the factory set “Alarm
Threshold”, the display indicates “50%ALM.” Since the operator is scanning
the device in clean air, it is assumed that the increase in the smoke measurement
is due to contamination of the smoke sampling chamber.
Typically, increased contamination of the smoke sampling chamber
automatically leads to increased smoke sensitivity of the detector. However, in
this case, the Simplex TrueAlarm detector compensates for chamber
contamination. The TrueAlarm technique compensates up to 50% to alarm
(50%ALM), while maintaining the detector’s full factory set sensitivity. If left
uncleaned, any additional contamination results in increased smoke sensitivity.
Note: The detector must be cleaned or replaced if it exceeds 50% to alarm
(50%ALM), or if both LEDs are illuminated.
The detector requires a full 24 hours to complete chamber compensation,
initially and if the device is reset, it returns to its factory set Alarm Threshold
value (see Figure 3). This leads to higher sensitivity initially, but as the
compensation proceeds the detector returns to its compensated sensitivity.
