Audible Alarm for Facility Safety

The EDWARDS-SIGNALING 340A-G5 is a surface-mount buzzer designed for indoor facility and traffic safety applications. It operates on a 24V AC supply drawing 0.250A and produces a continuous tone at 70 dB. The unit features a vibrating armature mechanism housed in a corrosion-resistant steel enclosure with a heat-flowed epoxy finish. It carries FM and UL listings for compliance with recognised safety standards.

Sustained Operation Characteristics

Under continuous duty the buzzer maintains its rated 70 dB output without cycling or thermal derating. The vibrating armature is built for uninterrupted running rather than short burst signalling. Power draw remains steady at 0.250A on the 24V AC circuit, so electrical loading is predictable for long-term installations. No visual indicator is present, so the device relies solely on its audible output for alerting.

Thermal and Acoustic Profile

The steel housing acts as a heat sink, keeping the unit cool to the touch during normal indoor operation. Acoustic output is a fixed 70 dB continuous tone with no volume adjustment or selectable patterns. Because the device is rated for indoor use only, it should not be exposed to weather or direct moisture. The corrosion-resistant finish protects the steel housing in typical indoor environments.

Questions about this item

How much heat or power does the 24V AC buzzer drawing 0.250A produce when running continuously?

At 24V AC and 0.250A the buzzer draws about 6 VA, so heat output is minimal and it can run all day without overheating.

What power supply and mounting hardware must I already have to install the 340A-G5 buzzer?

You need a 24V AC source capable of 0.250A and a flat surface with screws or bolts to match the 2.3438 in height and 5.1094 in width mounting footprint.

Will the 70 dB continuous tone of this steel buzzer work alongside older 24V AC alarm circuits?

Yes, the buzzer operates on standard 24V AC at 0.250A with a continuous 70 dB pattern, so it integrates directly with legacy 24V AC alarm wiring.
