Alarm module A9052T

Product features

• Nonpolar two-wire system.
• Inspection indicator blinks once about every 12 seconds in inspection status or remains lit in operation status.
• Complies with standard EN 54-18.

Product Info
The A9052T Zone module (A9052T module for short) is designed for use with addressable fire alarm control panels. It connects conventional photoelectric smoke detectors, conventional heat detectors or other conventional devices to an addressable loop. When a connected conventional device signals an alarm, the A9052T transmits the alarm to the fire alarm control panel via the loop.
