Safeguard Supply ERA-UTVPR Wireless Entry Alert and Portable Receiver Kit

Portable Entry Alert for Doors, Gates, and More

The ERA-UTVPR wireless entry alert kit combines two Safeguard Supply ERA Series components: the ERA-UTX extended range universal transmitter and the ERA-VPRX portable vibrating receiver. Together they create a flexible entry alert system that can act as a wireless doorbell, a door contact chime, or a combination of both. With a wireless range rated up to 4,000 feet in line-of-sight conditions, this kit is built for demanding commercial environments and larger properties.

The ERA-UTX is installed at the door, gate, or opening that needs monitoring, while the ERA-VPRX goes wherever the user goes. When the button is pressed or the door opens, the transmitter sends a signal to the portable receiver, which can vibrate, sound a chime, or do both to get the user’s attention.

ERA-UTX Universal Transmitter: Push Button and Door Contact

The ERA-UTX is a dual-function transmitter that works as both a push button and a magnetic door/window contact. In push button mode, the front button serves as a doorbell or call button. In door contact mode, the included magnet is aligned with the side of the transmitter so that opening the door separates the magnet and triggers an alert. In either configuration, the ERA-UTX sends a wireless signal to compatible ERA receivers.

The transmitter housing is weather-resistant, making it suitable for covered exterior doors as well as interior openings. It is powered by a CR2 lithium battery, chosen for long life in normal service. The wireless range is up to 4,000 feet line-of-sight, giving the system the reach needed for large facilities, multi-building sites, or long hallways.

• Transmitter type: dual-function push button and magnetic door/window contact.
• Wireless range: up to 4,000 ft line-of-sight to ERA receivers.
• Power source: CR2 3V lithium battery.
• Housing: weather-resistant enclosure suitable for covered outdoor and indoor use.
• Dimensions: approximately 2.0″ W x 3.75″ H x 0.875″ D.
• Frequency: 433 MHz.

Using the ERA-UTX in Push Button and Door Contact Modes

As a wireless doorbell button, the ERA-UTX is typically mounted near the main entrance, a side door, or a service door where visitors or drivers will press it for assistance. When the button is pressed, the transmitter sends a signal to the ERA-VPRX portable receiver, which alerts the user instantly. This setup works well for warehouses, retail stores, and offices that want a business-grade portable doorbell.

In door contact mode, the transmitter is mounted on the door frame and the magnet is mounted on the moving door. When the door opens and the magnet moves away from the transmitter, the ERA-UTX sends an alert. This configuration is ideal for back doors, interior doors to restricted areas, or gates where staff need to know when someone enters or exits.

• Push button applications: front doorbell, staff call button, drive-up or loading dock call.
• Door contact applications: rear doors, stockroom entries, internal doors, or swing gates.
• Mounting: surface-mount with screws or appropriate fasteners; magnet aligned closely for door contact use.

ERA-VPRX Portable Receiver with Sound and Vibration

The ERA-VPRX is a handheld, portable receiver that alerts users with sound, vibration, or both when an ERA transmitter is activated. It is powered by a rechargeable lithium-ion battery and is supplied with a charging cable and adapter. On a full charge, the receiver typically offers about six to seven days of standby time, depending on how often alerts are received and which modes are enabled.

The receiver supports four volume levels up to roughly 80 dB and provides multiple melodies, allowing each transmitter to have its own unique tone. It can be set to sound only, vibrate only, or sound and vibrate simultaneously. A backlit display and indicator icons show when an alert arrives and provide basic information about the receiver’s status.

• Alert modes: sound only, vibration only, or sound plus vibration.
• Volume: four adjustable levels up to about 80 dB, plus mute.
• Wireless range: up to 4,000 ft from ERA transmitters in line-of-sight conditions.
• Power: rechargeable lithium-ion battery with charging cable and power adapter.
• Battery life: approximately 6–7 days of standby time per charge, usage dependent.
• Transmitter capacity: supports pairing with up to 16 ERA transmitters or sensors.
• Dimensions: about 4.0″ H x 1.5″ W x 0.75″ D.
• Operating temperature: approximately -30°F to 120°F.

Portable Entry Alerts for Busy Facilities

With the ERA-UTVPR kit installed, a door opening or button press at the ERA-UTX immediately sends a signal to the ERA-VPRX portable receiver. Staff carrying the receiver feel the vibration, hear the selected tone, or both, ensuring they are aware of the event even if they are far from the door or in a noisy part of the building. Because the receiver is portable, it keeps working as the user moves between rooms, aisles, or buildings within range.

If additional transmitters are added to the system—such as extra ERA-UTX units at other doors—each can be assigned a distinct melody. This enables the user to tell which door or area triggered the alert simply by listening, without needing to look at the display every time.

• Alert path: push button press or door opening at ERA-UTX triggers sound and/or vibration on ERA-VPRX.
• Mobility: receiver can clip onto a belt or fit in a pocket for continuous coverage.
• Multi-point support: multiple transmitters can share the same receiver with unique tones.

ERA Series Compatibility and Expansion

Both the ERA-UTX and ERA-VPRX are part of the Safeguard Supply ERA Series, which supports a wide range of compatible transmitters and receivers. In addition to the included ERA-UTX, the ERA-VPRX can be paired with driveway sensors, indoor motion sensors, doorbell extenders, and additional push buttons, up to sixteen transmitters in total. Each transmitter can have its own melody and, if desired, its own vibration pattern and notification settings.

The ERA-UTX transmitter can also be paired with other ERA receivers—such as desktop chime receivers or plug-in strobe receivers—if you later want both portable and fixed alerts. There is no fixed limit to the number of receivers that can listen to the same transmitter, so you can build a system that fits changing needs over time.

• Series: Safeguard Supply ERA long-range wireless platform.
• Compatible transmitters: ERA-UTX plus other ERA push buttons, motion sensors, driveway sensors, and extenders.
• Compatible receivers: ERA-VPRX and additional ERA receivers such as ERA-DCRX and ERA-RXPG.
