User Pushbutton Controls
Test
Pressing the ‘test’ pushbutton will immediately cancel programming mode
if active.
Pressing and holding the test pushbutton for more than three seconds will:
Illuminate all LEDS except the Telco line active and alarm contact active LEDS
Sound the audible device steady on
Activate the common trouble relay
Transfer the programmed (or default RX) manual test event code to the SIA transmitter, which
will initiate a dialing operation as described above.
The LEDS, audible and common trouble relay will remain active for as long as the test pushbutton is held.
Program
Pressing the ‘program’ pushbutton will place the Keltron S/FDACT into programming mode in order to
download the configuration program to a PC, or upload a new configuration program from a PC.
When the S/FDACT enters programming mode the serial port baud rate and other settings will
automatically change to match those required by the S/FDACT programmer PC software. For SDACT
only, the FACP personality software will be disabled, and the serial port supervision feature will be
disabled allowing the user to disconnect the FACP, and connect the serial port to his PC or laptop.
While in programming mode, the red and yellow serial port LEDS will alternately light once a second as
an indication that programming mode is active.
If there is no serial port activity for 60 seconds, the S/FDACT will time out and resume normal
monitoring mode. Pressing the test pushbutton also causes immediate return to normal monitoring mode.
Silence
Pressing the ‘silence’ pushbutton will silence the audible device.
The audible device will sound immediately if a new initiating condition occurs.
Reset
Additionally, there is a reset pushbutton, which is not meant to be used in normal operation. Pressing this
pushbutton will reset the on-board microcontroller, which places both telephone lines on-hook, releases
any line seizures, clears all pending events from the SIA transmitter, and clears all memory of off-normal
conditions. Any off-normal conditions present after reset are treated as new events.
CAUTION
: DO NOT RESET the S/FDACT while it is writing to its EEPROM memory as
a result of uploading a new configuration in programming mode. Doing so could corrupt the
stored configuration and make it unusable. A “Configuration Trouble” will result. This can
be corrected by restarting programming mode, and uploading the new configuration again.
