Industrial 75-OBA Dual Bell Telephone Alarm Bell

The ITT 75-OBA Dual Bell Telephone Alarm Bell is an industrial-grade audible alert device designed for telephone-based alarm systems. This dual-bell unit (model 75-OBA) from ITT provides two bells to deliver a clear audible warning in industrial environments when an alarm condition is signaled. As the audible component of a wired telephone alarm setup, it is intended to alert personnel on the shop floor, control rooms, and facility monitoring areas, enabling rapid recognition and response. Typical applications include process control alarms, safety interlocks, and plant monitoring systems where a dedicated audible alert is required. The dual-bell design helps ensure the alarm is audible over ambient noise, supporting timely coordination during incidents, routine testing, or maintenance activities.
