    How to obtain a Pulsing Output from terminal 6 of the D8112 panel types?

    Terminal 6 on the D8112 does not provide a pulsing output when a fire point is tripped.
    Pulsed Bell Output for fire on the D8112 is dependant on what is programmed into Item #75 PULSE. It is a Yes or No value. To begin, the fire circuit's zone code should be programmed as a 3181. This code gives the standard fire response of trouble on an open circuit, instant alarm on a short circuit, and restoral reports.

    Assuming there is a D136 Relay inserted in socket K6 to activate terminal 7 (Alternate Alarm output), the following occurs:

    • If Item #75 PULSE is programmed as Yes, a fire alarm creates a pulsing 12 VDC output on Terminal 6 (Main Bell Output) and a steady 12 VDC output on Terminal 7. On a non-fire alarm, Terminal 6 produces a steady output, and Terminal 7 produces no output.
    • If Item #75 PULSE is programmed as a No, a Fire alarm creates no output on Terminal 6, and a steady output on Terminal 7. On a non-fire alarm, Terminal 6 produces a steady output, and Terminal 7 produces no output.
    • Terminal 6 is the only output that can be made to pulse. Terminal 7 always produces a steady output on a fire alarm, regardless of whether Item #75 PULSE is programmed as Yes or No.
