Vibrating bell for traffic safety

The EDWARDS-SIGNALING 340-4G5 is a steel vibrating bell rated for 24V AC operation at 88 dB. It provides a continuous audible signal without a visual indicator for indoor or outdoor facility and traffic safety applications. The gray steel housing measures 4.5 in diameter with a 4 in height and 2.4063 in depth. This unit is not suited for buyers who need a visual strobe or a different voltage supply.

Sustained continuous sound output

The bell produces a continuous vibrating tone at 88 dB when powered, designed for ongoing alerting rather than short bursts. It draws 0.250A at 24V AC during operation. The mechanism maintains its output pattern as long as voltage is applied. Installations needing intermittent or coded patterns cannot use this continuous-only device.

Weatherproof with proper back box

The steel housing is weatherproof when mounted with an appropriate back box, allowing reliable outdoor use. UL and FM listings confirm compliance with safety standards for the intended environment. The 0.250A draw at 24V AC keeps power demand modest for continuous duty. Buyers without a suitable back box or conduit entry will not achieve the rated weather protection.

Questions about this item

How much noise and heat does the 340-4G5 bell produce when it runs continuously all day?

The bell emits a continuous 88 dB tone at 24 V AC while drawing 0.250 A, so acoustic output is steady and electrical heat is minimal.

What mounting hardware or back box must I already have to install the 340-4G5 vibrating bell?

The unit includes its own mounting hardware; a separate weatherproof back box is required only if you need outdoor weather protection.

Will the 24 V AC 340-4G5 bell work with my existing 24 V AC fire-alarm circuit?

Yes — it operates on 24 V AC, draws 0.250 A, and carries FM and UL listings, so it integrates directly with compatible 24 V AC notification circuits.
