What type of alarm notification system sends a signal to a 3rd party offsite monitoring facility?

The choice of a Central Station Service Alarm as the correct answer stems from its design and function in alarm notification systems. A Central Station Service Alarm is specifically engineered to transmit signals from the alarm system to an offsite monitoring facility. This facility continuously monitors incoming signals for any alerts, such as fire, intrusion, or other emergencies.

When an alarm is triggered, the central station receives this notification immediately and can take appropriate action, which may include contacting the relevant emergency services or dispatching trained professionals to address the situation. This type of system is essential for ensuring a rapid response to emergencies, particularly in locations where immediate on-site monitoring is not feasible.

In contrast, a Local Alarm is typically self-contained and only alerts individuals in the immediate vicinity without notifying any outside services. A Manual Alarm requires a person to physically activate it for the alert to be sent; it usually does not have the automated communication capabilities of central station alarms. A Direct Wire Alarm may involve connections to local systems or other devices, but it does not inherently provide offsite monitoring like a Central Station Service Alarm does.
