ABAT ABAT Communication Systems & Central Station Monitoring 2 — Questions and Answers
Question 1: When a cellular communicator loses its connection to the cellular network, what should a properly configured alarm system do?
- Immediately trigger a local siren
- Log the event and switch to the backup communication path (Correct answer)
- Disable all zones until connectivity is restored
- Notify the user via keypad only
Correct answer: Log the event and switch to the backup communication path
A properly configured dual-path system logs the cellular trouble condition and automatically fails over to the secondary communication path (e.g., IP or POTS) to maintain monitoring.
Question 2: What is 'line seizure' in the context of alarm communicators using POTS lines?
- The panel disconnecting all extensions to gain exclusive control of the phone line for dialing (Correct answer)
- A central station override that remotely locks the phone line
- A surge protection feature that disconnects the phone line during lightning
- A diagnostic mode that tests telephone line voltage
Correct answer: The panel disconnecting all extensions to gain exclusive control of the phone line for dialing
Line seizure is the communicator's ability to disconnect all phones in the premises and seize the POTS line to ensure the alarm signal is transmitted without interference.
Question 3: Which central station grade under UL requires the facility to be located in a building with reinforced walls and dedicated backup power?
- Grade A
- Grade AA (Correct answer)
- Grade AAA (highest)
- Grade I
Correct answer: Grade AA
UL Grade AA certified central stations must meet more stringent physical security and redundancy requirements than Grade A, including reinforced construction and comprehensive backup systems.
Question 4: In alarm monitoring, what does 'test signal' or 'test report' scheduling accomplish?
- Verifies that communication between the panel and central station is functioning at regular intervals (Correct answer)
- Tests the volume of the local siren
- Resets the alarm panel clock
- Checks zone wiring continuity
Correct answer: Verifies that communication between the panel and central station is functioning at regular intervals
Scheduled test signals (e.g., daily or weekly) confirm that the end-to-end communication path from the alarm panel to the central station is operational.
Question 5: What is the significance of the SIA DC-09 standard in alarm communications?
- It defines the wiring standards for alarm panel installations
- It specifies IP-based alarm transmission using TCP/UDP protocols (Correct answer)
- It sets the minimum battery backup requirements for communicators
- It governs the licensing requirements for central station operators
Correct answer: It specifies IP-based alarm transmission using TCP/UDP protocols
SIA DC-09 (Internet Protocol Event Reporting) defines how alarm events are transmitted over IP networks using TCP and/or UDP, enabling modern broadband alarm communications.
Question 6: A central station operator receives a burglary alarm signal and cannot reach the subscriber or any keyholders. What is the standard next step?
- Cancel the alarm and log it as unverified
- Dispatch police immediately (Correct answer)
- Wait an additional 10 minutes before acting
- Send a test signal back to the panel
Correct answer: Dispatch police immediately
When a verified alarm cannot be resolved through call verification, standard central station protocol is to dispatch law enforcement immediately to protect the subscriber's property.
