For the operational check, it is necessary to use the radiation check source
provided with the instrument to ensure proper alarm function. When the check
source is not being used, store the check source in a secure area.
Note:
LMI check sources present minimal risks and are therefore unlicensed
(Exempt Quantity Sources reference: 10 CFR 30.71 Schedule B). The
radioactive element is sealed (permanently bonded or fixed inside a
capsule). Consequently, cleansing of the users skin after contact is not
deemed necessary. Radiation exposure while handling this source is
minimal with no identified long or short-term risks. Although the amount
of radiation given off by exempt sources is so low that it presents no
significant hazard, they should be handled with care and respect. Time,
distance, and shielding are the best ways to control exposure.
1. While placing one hand in front of the infrared sensor, position the check
source over the “Ludlum Measurements, Inc.” sticker on the detector.
a. The
CHECKING
light on the remote display should now be lit, and
the Supervisor software should show that the lane is occupied.
b. After three to four seconds, remove the source from the detector
and your hand from in front of the sensor.
2. Verify that the alarm circuit is activated by checking to see if the alarm
light(s) is on. Any other remote alarm indicators should also be activated
(i.e. strobe or horn if applicable) and the Supervisor software (if used)
should display an alarm “popup” message.
3. Press the
ALARM RESET
button, or if the alarm hold time is set to a non-
zero number, wait until the alarm automatically clears.
a. All alarm indicators should go off, including any remote strobe or
horn (if applicable).
b. The “popup” alarm window must be cleared manually, by clicking
on the “X” in the upper right-hand corner.
4. Repeat the procedure for any other active radiation detector and each
infrared vehicle sensor pair. Once completed successfully, the system is
ready for normal operation.
