Final answer:
A tamper alarm on a pull-station is connected to a fire alarm system to signal unauthorized interference. The connection typically involves a circuit that sends a signal to the control panel when the pull-station is tampered with, which alerts the monitoring staff for immediate response.
Step-by-step explanation:
The tamper alarm on a pull-station is an integral component of a fire alarm system. In essence, a tamper alarm is designed to signal when there is an unauthorized interference with the pull-station. This ensures the integrity of the fire alarm system is maintained and prevents malicious attempts to disable it.
Typically, the connection involves a circuit that completes when the pull-station handle is moved from its normal position. When this circuit is completed, the tamper alarm sends a signal to the main control panel, which can then initiate an alert condition, sometimes distinct from a fire signal, allowing for immediate response and investigation.
More advanced systems may include electronic monitoring of the pull-station's status, where any irregular activity such as opening the station's casing, cutting wires, or an attempt to pull the alarm without actually triggering it, will also cause an alarm and notify the system's central monitoring location.
