After small fire in my house (dishwasher caught on fire) my hard wired smoke detector (no battery in this head) has the permanent red light on. I have 4 electronic smoke detectors with battery backup on the same line. There is no beeping, just a red light on. Is this normal?

All the hard wired smoke detectors in our apartment have a red light that stays on all the time.
Just to be sure I would call the fire department and/or an electrician to ask to be safe rather than sorry.
