sensors not triggering alarm

Here is an perplexing problem Alarm: Scytek Galaxy 5100 Sensors: Microwave, Glass breakage, Dual-stage Shock, Tilt. Everything works on the alarm minus the sensors, the hood pins, the door pins trigger the alarm. First thought, bad connections. I have diode isolated each sensor from each other using the n4001 diodes with cathode(the bands) facing the sensors since the trigger wires are negative. I ran a diode test to make sure that the diodes were blocking the signals the correct way & to make sure there is continuity between the sensor plugs & the sensor plug location on the alarm module. But no matter what I do I can't get the alarm to trigger from the sensors, the led(s) on the sensors will flash indicating they are tripping but the alarm never goes off. I unplugged all but one sensor(it varied which one) & would try triggering the alarm & even removing the diode so it was a 'straight shot' from the sensor to the alarm module with the brain still never sensing a trigger. I'm at a loss as to what it could be and what to try & am asking for some suggestions on what the issue may be & what to try to solve it. TL;DR: sensors tripping but not triggering alarm even though their diode blocked properly & the wiring is good.

My alarm has a 30 wait time before it becomes active. The armed led will be steady on while arming then blink once a second when armed. I haven't yet grounded the sensor warning or sensor trigger wires from the alarm straight to ground. I'll do that one tomorrow & see what happens.
