Latching Flashing LED Heat Alarm

Really new at this but looking to build a circuit for a project that would allow and LED to flash until reset which is triggered by a heat sensor. Ive simulated a circuit which uses a Thermistor and an SCR to latch at a certain temp but unsure how to then build in a flashing LED to this?

Any help would be great, thanks
