2.0 Equipment Description & Operation
2.1 PAM-TRX (Personal Alarm Module Transmitter)
2.1.1 Features:
•
High volume buzzer, 85 dBA at 2200
±
500 Hz mounted on the
top of the enclosure facing the user
•
Two high intensity multicolor LED’s. One facing the user on
top of the enclosure and one on the enclosure front to facilitate
monitoring by other workers in the vicinity of the user. The
LED indications: GREEN flash to indicate data transmission
and a good battery and, RED to indicate a local alarm triggered
by the dosimeter. An option configuration consists of a BLUE
flash to indicate the receive function is on, and data is being
received by the PAM-TRX (used for RF mapping applications).
•
Driver and connector for external alarm devices: LED,
Earphone, EAM, etc.
•
External DC supply capability.
•
Single ‘AA’ Battery that can provide over 35 hours of
continuous operation with one hour of continuous alarming.
•
Low battery indication
The PAM-TRX has a stereo jack to allow connection to the LED or earphone output, an 8 pin
connector to connect to a PC to allow radio programming and a power jack to allow connection of
an external power supply used to operate the alarms and the transmitter for area monitoring
applications.
The pattern of the audible and visible alarm signals are the same as the alarm signal from the
dosimeter - fast pulsating signals are integrated into a single alarm level to improve the
effectiveness of the vibration alarms. The PAM-TRX can be configured to latch the dose rate
alarm from the dosimeter.
CAUTION: If the optional alarm latch feature is enabled, once the latched alarm is
triggered, it is necessary to remove the battery to terminate the alarm condition.
Testing the alarm functions (red LED, vibrator and buzzer) is performed by pressing the test button
through the back of the enclosure. If the ILS feature is enabled, the alarm can be tested by placing
a magnet in proximity to the side of the enclosure.
