3.6. Low Voltage Alarm.
Whenever the system voltage drops below 11.9 volts for a 12 volt system or 23.8 volts for a 24 volt system a low
voltage alarm output is activated. This complies with the N.F.P.A. 1901 requirements.
3.7. Switch Sources.
Each load can be programmed to activate by either the Ignition switch or the Warning Master switch.
Ignition: Loads programmed for ignition will sequence on when the vehicle ignition switch is turned ON.
Warning Master: Loads programmed for master warning will sequence on when the master warning switch is turned
ON.
3.8. User Setpoint / Variable Trip.
This is the user definable output. The user has the option of selecting a 'trip' voltage between 10.5 and 14.5 volts for a
12 volt system or between 21.0 and 29.0 volts for a 24 volt system. If the trip point is set to 13.8 volts or above on a
12 volt system or set to 27.6 volts or above on a 24 volt system the output acts as an overvoltage indicator and will
turn on when the selected voltage is reached. If the 'trip' voltage is set below 13.8 volts for a 12 volt system or 27.6
volts for a 24 volt system the output will activate when the voltage drops to the setpoint.
3.9. Auxiliary Battery Monitoring.
Terminal #23 can be used to monitor an auxiliary battery. There should be no connections to this terminal if a remote
battery is not monitored. If the auxiliary battery voltage drops below 11.9 volts on a 12 volt system or 23.8 volts on a
24 volt system the auxiliary battery output will turn on.
3.10. Output Modes.
Each load can be programmed for RESPONSE MODE, SCENE MODE, OR BOTH.
Response Mode: The output is ON only when the Park Brake is NOT set.
Scene Mode:
The output is ON only when the Park Brake IS set.
Both: The output is ON in both Response and Scene Mode.
3.11. Output Polarity.
All Outputs can be user selected to operate as a High Side or Low side Output.
3.12. Operating voltage.
The unit will operate from 7 to 32 volts DC.
3.13. Outputs.
Every output is user selectable to be a High side or a Low Side driver.
High Side: Vmain at 0.5 amp (source).
Low Side: Ground at 0.5 amp (sink).
3.14. Transient protection.
The main power supply and all outputs are protected against direct shorts and transient spikes.
