Alarmed and Dangerous

Here's a shot of Elgar using the Periscope.

Here's a shot of a Fire Extinguisher Detonator.

Here's a shot of 2 Piranhatrons after they set off a fire alarm.

Here's new footage of Elgar and Rygog in Angel Grove due to the fact they're seen in the same shot as the Fire Truck and you can see part of the Fire Truck's text on it says "Angel Grove."

All of the footage on Elgar and Rygog from when they teleport in by the Fire Truck until Elgar plants the Detonator on the Truck and activates it and then the 2 of them teleport away is new footage. It looks like all scenes of the 5 Rangers on the scene where the Fire Truck is at is new footage until the Truck turns into an evil Fire Truck monster which is called Blazinator. Once it turns into Blazinator, all footage of Blazinator is Sentai and I believe all footage of the Rangers is Sentai at that point too. All footage of Elgar, Porto and Rygog facing the 5 Rangers is also Sentai. This shot of the Red, Pink and Green Rangers is more than likely new footage.
