Final answer:
The city of Seattle has certain requirements for alarm systems, but the use of Electronic Communication Verification for alarms may vary.
Step-by-step explanation:
The question pertains to whether the city of Seattle has a specific requirement for Electronic Communication Verification (ECV) when it comes to alarm systems. ECV is a protocol used to reduce false alarms by attempting to verify the alarm event typically through multiple call attempts to different numbers associated with the account before the police dispatch is requested.
In Seattle, the Seattle Police Department does have requirements surrounding alarm systems, including permits and false alarm fees, but the specific adoption of ECV protocols can vary based on the alarm company and local jurisdiction requirements. Therefore, for the most accurate and up-to-date information, it's recommended to directly consult with the Seattle Police Department or an authorized alarm service provider.
For definitive information, contact the Seattle Police Department or a licensed alarm service provider in the area.
