Assume you wish to quantify the alarm system requirements - see below. You might start with the following: (a.1) Intrusion shall be detected within (TBD) seconds (a.2) CO shall be detected above a level of (TBD) ppm (b) The system shall connect with EMS within (TBD) minutes (c) Owner shall be able to operate system after (TBD) minutes of training (e) The system shall operate (TBD) hours without external power For each requirement, list the factors that would be traded off when considering what value to choose. Explain how you would decide on the right value. You DO NOT have to decide what the value should be.

System Requirements:

This system will be used in homes and small businesses to detect intrusions, fire, smoke, and carbon monoxide.

The system will be interconnected with a monitoring service and appropriate government Emergency Response Services (EMS) (fire, police, etc.).

The system will be operated by the building owner or manager via a simple user interface

The system must be secure against tampering or disablement

The system must be able to operate over long intervals without external power

You may add other requirements that you feel are necessary
