Color
Yellow Illuminates when the real time clock is not functioning properly. It also may light during power-up after the
UDACT-2 has been turned off for awhile. To ensure that the UDACT-2's time is accurate, extinguish the LED
by downloading the database, waiting 3 minutes, then pressing reset. (The UDACT-2 will get the correct time
from the PC that does the download.) The light will extinguish within 3 minutes if the reset button is pressed
without downloading the database, but the time may not be accurate without the accompanying download.
Red LINE SEIZE PRIMARY - Illuminates when the primary phone line is seized.
Yellow LINE FAILURE PRIMARY - Illuminates when the primary phone line voltage test fails.
Yellow NO TONE PRIMARY - Illuminates when the primary phone connection does not receive a "handshake" tone
from the Central Station. When the UDACT-2 is in transmit/receive mode, a trouble message is sent to the
panel.
Red KISS OFF PRIMARY - Illuminates when the Central Station does not acknowledge receipt of each
transmitted message from the primary telephone.
Yellow COMMUNICATION FAILURE PRIMARY - Illuminates when the maximum number of attempts to reach both
Central Stations has failed over the primary telephone line.
Yellow • Illuminates during initial SDRAM test during power up. Goes out when test is successfully completed. If
this LED remains on for more than 30 seconds during power up, contact Customer Service for a
replacement.
• Illuminates when the UDACT-2's Class B relay outputs are de-activated, indicating the UDACT-2 is in
trouble.
• Illuminates in bootloader mode once the UDACT-2 is ready for download.
Green Illuminates when there is 24VDC power.
Red Illuminates when a manual test has been initiated by pressing SW3 on the UDACT-2. The LED goes off
automatically when the test transmission is complete.
Green COMMUNICATION ACTIVE - Illuminates during USB communication.
Red LINE SEIZE SECONDARY - Illuminates when the secondary phone line is seized.
Yellow LINE FAILURE SECONDARY - Illuminates when the secondary phone line voltage test fails.
Yellow NO TONE SECONDARY - Illuminates when the secondary phone connection does not receive a
"handshake" tone from the Central Station. When the UDACT-2 is in transmit/receive mode, a trouble
message is sent to the panel.
Red KISS OFF SECONDARY - Illuminates when the Central Station does not acknowledge receipt of each
transmitted message from the secondary telephone.
Yellow COMMUNICATION FAILURE SECONDARY - Illuminates when the maximum number of attempts to reach
both Central Stations has failed over the secondary line.
Yellow • Illuminates while the initial CRC test is in progress. Turns off when this test has been successfully
completed. If this LED remains on for more than 10 seconds during the initial CRC test, try downloading
the application or database again.
• Illuminates while downloaded application or database information is moved from the SDRAM to the
UDACT-2's memory. It turns off when this process is complete. The DIP switch may be changed at this
time back to the OFF position.
Yellow Lights any time a tone is detected on a UDACT-2 phone line.
Table 1.3 LED Indicators
Set to ON when downloading an application. Set to OFF when downloading is complete. Normally OFF.
The piezo sounds when troubles are found at startup, or when the UDACT-2 is in trouble. UDACT-2 troubles are:
• EIA-485 fail
• phone line voltage test fail
• phone line communication fail
• no handshake tone detected.
Connects a 120 Ohm terminating resistor on the EIA-485 bus when set to ON. Set to ON when the UDACT-2 is
the last or only EIA-485 device.
Press and hold this button switch down for over 3 seconds to immediately stop UDACT-2 transmissions, hang up
from the telephone network, clear out any messages that were waiting for transmission and reset, and return to
normal system processing.
