Need an entrance alert with enough power to penetrate metal doors and travel a long distance? The ERA-UTDCR is a wireless entrance alert product created by Safeguard Supply and featured on 1800doorbell.com specifically designed for business doorbell use. Most contact based door/window entrance alerts have trouble when attached to metallic door frames. The wireless signal bounces off the metal and due to limited power, don’t seem to have the power to reach the receiver. The extra power of the ERA-UTDCR will reach a receiver up to 4,000 ft. away.

The ERA-UTDCR is a long range wireless door chime kit specifically designed for warehouse and business use. Most wireless products do not have the range needed to work effectively in a warehouse or business environment. The ERA product line has a wireless range of up to 4,000 ft. from transmitter to receiver. This range ensures reliability and that your kit will offer the functionality of wireless products with the reliability of wired products. The kit may also be expanded by adding more receivers and transmitters, as well as connecting devices like strobes, sirens, and buzzers to the live 12V DC outputs on the receivers.
