Narrative: I briefed the crew like I always do; but emphasized to both pilots and FAs the fact that we are making a lot of mistakes. I encouraged everyone to stick to SOP and work together as a crew.We pre-flighted the aircraft and I made a point to be diligent. That said; you get interrupted and this was the case with my normal inspection of the circuit breaker panel. I normally do this as so as I go into the flight deck. In this case; the FO was not in their seat fully; so I accomplished some initial items; then stepped back. When I returned; I failed to inspect the C/B panels. If I had; I'd have noticed the collared C/Bs for every probe heater.I went through my overhead flow although I checked the probe heat; I didn't notice that the lights never went out. I think this is possibly due to the fact that every probe heater was ions; so the whole light panel for these probes was lit; as opposed to noticing if only one light failed to extinguish. My error.We continue with our procedures and briefly noticed before taxi that the panel anti-ice light was lit. The FO jiggles the button and it extinguished. We figured it was just the panel acting up; which it often does. This is a human factors issue. We have become so de-sensitized to the panel not working that when we get an indication like this; we think nothing of jiggling the switch and continuing if the lights go out. I have the panel stick many times and often when we check it; it take numerous presses from both pilots to get the system to test. This is normalization of deviation; both from and SOP standpoint; but also from a design and system failure standpoint. We all know this system is poor.When the anti-ice light went out; we continued to takeoff; checking the panel once again; and got no lights. We took the runway and at about 30 knots; the Master Caution light lit up and I took the aircraft and rejected the takeoff. We ran the checklist and cleared the runway to troubleshoot. We had gotten the Master Caution with no associated panel light illuminated. This is not right. We jiggled both panel lights and the anti-ice light in front of the FO came on steady. It should have been on; the entire time. I called Maintenance Control and after talking with the; I taxied back to the gate for maintenance.They discovered that when the aircraft was pulled from storage; that all the C/Bs for the probe heaters were still collared.Takeaways for me:- Late night departure.- Lack of recent experience; proficiency.- Interrupted SOPs during preflight.- Myopia to the illuminated probe heat lights because they were all on. This is not common and doesn't stick out. This may seem strange; but we both looked at the overhead panel numerous times; and even though all the probe heat lights were on; it didn't stick out. If only one had been on; it would have been salient.- The panel system doesn't work right. We all know this and have learned to accept it. That said; I think we all believe this system needs fixing. It sticks and doesn't test very often.


Second narrative: Scheduled push of XA:55 local. 3rd flying leg in the previous 33 days. Due to various reasons both the Captain and I completely missed the CB check during our preflight flow. During the recall test for the after start flow; the MC light and Anti-ice annunciation on the panel illuminated. We checked the overhead panel; and the window heat looked normal (no overheat; all green). We then checked the probe heat panel and all of the amber lights were on; however our brains incorrectly registered it as 'normal' since there wasn't a broken up pattern (expecting to see one or two lights not in the same state as the others). We then retested the recall check it did not illuminate the MC light or any panel annunciations; even during the recall checks of all subsequent flows. During the takeoff roll; before the engines even achieved T/O N1; the MC light illuminated but no panel annunciations illuminated. The Captain executed a low speed RTO and stopped on a taxi way to troubleshoot. We checked and cleared the recall test multiple times because the only light that kept illuminating was the MC. Only after several recall tests did the anti-ice annunciation on the panel illuminate again. After discussing the situation with Maintenance Control we ended up returning to the gate. Operations started asking us questions and troubleshooting the anti-ice systems. After a couple minutes; the Captain realized that we had completely forgotten to check the CBs and we started looking for any popped CBs. We then saw all the pitot heat CBs pulled and secured with big red collars and flags even though the maintenance release we had was valid. Operations re-secured the CBs and we were on our way.


Synopsis: Air carrier flight crew reported rejecting a takeoff in response to multiple warning lights. The aircraft had been in storage and anti-ice circuit breakers had been collared and not removed by Maintenance prior to flight.
