How long would it take a sound wave from a car alarm to travel 1 km if the temperature were 20 degrees celsius?
A decent estimate of the speed of sound at sea level in dry air is (331.3+0.606*T)m/s where T is in °C. That means that at 20 °C, the speed would be about 343.2 m/s. Using that value, you get an estimate.of about 3 seconds (2.912 from the equation) for a sound wave to travel 1 km. Factors that can change it include: altitude (as pressure drops, the speed of sound decreases), frequency (in dry air, the speed of sound increases by about 0.1 m/s as the frequency rises from 10 Hz to 100 Hz, but above 100 Hz, where pretty much all car alarms sound, it's essentially constant), and humidity (the difference between 0% and 100% humidity is about 1.5 m/s at standard pressure and temperature). None of these effects are anywhere near as significant as the temperature of the air though.

What is the meaning of High casing temperature alarm?
A high temperature alarm is an alarm unit that is utilized in industrial settings for fire monitoring. The alarm utilizes sensors to detect possible overheating activity within an industrial environment.
How do you eliminate scavenging high temperature alarm?
A scavenging high temperature alarm can be eliminated by disconnecting the wires feeding it and removing it from the circuit. Some connections may have to be looped together to allow electricity to continue to flow properly.
What is a heat detector?
A heat detector is a device designed to sense a significant increase in temperature, typically above a certain threshold. It is commonly used in fire alarm systems to detect fires in areas where smoke detectors may not be suitable, such as kitchens or areas with excessive dust. When the temperature rise is detected, the heat detector triggers an alarm to alert occupants of potential fire hazards.
What is touch alarm?
A touch alarm is a type of alarm system that is activated or deactivated by touch. It typically involves a touch-sensitive interface that allows users to set or disable the alarm by touching a specific area or button on the device. This type of alarm can be found in alarm clocks, security systems, and other devices that require manual activation.
Does the heat detector melt?
Heat detectors do not melt; instead, they typically use a bimetallic strip or a thermistor that responds to changes in temperature. When the ambient temperature reaches a specific threshold, the detector activates an alarm. Some types of heat detectors may have components that can be damaged by extreme heat, but they are designed to function within a certain temperature range.
