Dakota Alert SMA-4000 Indoor Motion Entrance Alert with SR-4000 Smart Receiver

Indoor Motion Entrance Alert with Smart Receiver

The Dakota Alert SRPR-4000 is an indoor motion entrance alert kit that combines a PIR-4000 passive infrared motion sensor with the SR-4000 smart receiver to provide door and hallway alerts, smartphone notifications, and integration options through 12VDC outputs and a Form C relay contact. When the PIR sensor detects movement, the transmitter sends a wireless signal to the plug-in receiver, which plays a selected chime tone and can also trigger external equipment or app-based notifications.

Motion Detection for Doors, Hallways, and Interior Entrances

The PIR-4000 passive infrared sensor is designed to detect people walking through a defined indoor area, making it suitable for use as a store entrance alert, hallway motion alert, or interior doorway notification in retail, office, and light commercial settings. Installed near a doorway or corridor, the sensor watches for body heat movement within its coverage pattern and sends a wireless signal when motion is detected.

This type of motion entrance alert is useful where staff need a simple indication that someone has come through a door or entered a monitored interior space, without installing a full alarm panel or complex security system.

• Typical placements: interior doorways, hall entrances, small lobbies, and point-of-sale approaches.
• Detection method: passive infrared sensing of people moving through the coverage area.
• Use cases: customer entrance alert, backroom notice when someone comes in, basic interior monitoring.

PIR-4000 Indoor Motion Sensor Details

The PIR-4000 is a compact, battery-powered indoor motion detector that monitors a defined area for walking traffic. It operates from a CR-123A lithium battery and is sized for unobtrusive mounting near ceilings, in corners, or above door frames. The sensor uses passive infrared technology to look for changes in heat caused by people moving through its detection field.

When motion is detected, the PIR-4000 transmits a wireless signal to a compatible Dakota Alert 4000 Series receiver, such as the SR-4000 smart receiver included in this SRPR-4000 kit. This wireless link allows the sensor to be installed where it has the best view of the monitored area, without needing to run low-voltage signal wires back to the receiver.

• Power source: CR-123A lithium battery.
• Indoor use: intended for interior spaces such as entries, hallways, and rooms.
• Wireless operation: sends alerts to Dakota Alert 4000 Series receivers.

SR-4000 Smart Receiver with Plug-In Entrance Alert Chime

The SR-4000 smart receiver is a plug-in unit that listens for signals from the PIR-4000 and other Dakota Alert 4000 Series transmitters and provides local audio alerts plus smart notification features. When the PIR-4000 detects motion, the SR-4000 can play one of its built-in melodies so staff know that someone has entered the monitored area. The receiver plugs into a standard outlet, making it easy to locate in an office, counter area, or back room where the chime needs to be heard.

In addition to entrance alert chimes, the SR-4000 connects to the Dakota Alert app over Wi‑Fi, allowing smartphone-style notifications when the motion sensor is triggered. This helps ensure alerts are not missed in noisy environments or when the chime is not in direct earshot.

• Audio alerts: multiple selectable melodies for different zones.
• Plug-in design: powered by 12 VDC adapter, compact form factor.
• Wireless range: up to approximately 1 mile line-of-sight from compatible transmitters (actual range depends on site conditions)

Wi‑Fi Connectivity and Smartphone Notifications

The SR-4000 receiver supports Wi‑Fi connectivity and works with the Dakota Alert mobile app to provide push notifications when an entrance alert is triggered. When the PIR-4000 detects motion and sends a signal to the SR-4000, the receiver can activate its chime and also send a notification through the app, providing a text-style alert on a compatible smartphone.

This configuration allows the SRPR-4000 kit to function as both a local motion entrance chime and a remote notification device, which is particularly useful when staff move between areas of a building or when a single receiver must cover multiple zones.

• App support: Dakota Alert app for smartphone notifications.
• Notification type: push-style alerts when a new motion event is received
• Intended use: supplement audible chimes with phone-based entrance alerts.

12VDC Outputs and C‑FORM Relay for Integration

In addition to chime tones and app notifications, the SR-4000 smart receiver provides low-voltage outputs and a Form C relay that can be used to drive external devices or interface with other systems. The 12VDC outputs can be configured to activate when a specific zone is triggered, allowing connection to accessories such as indicator lights, small sirens, or other low-voltage signaling equipment (within rated current limits).

The built-in Form C relay contact offers a dry-contact interface suitable for integration with alarm inputs, automation controllers, or third-party notification hardware.] This allows installers to use the SMA-4000 as both an entrance alert and a triggering device for broader security or automation applications where a contact closure is required.

• Outputs: 12VDC output terminals on the SR-4000 for external signaling devices.
• Relay type: Form C relay contact for dry-contact integration.
• Integration options: connect to strobes, external sounders, dialers, or automation inputs where appropriate.

Dakota Alert 4000 Series Compatibility and Expansion

The SMA-4000 kit is part of the Dakota Alert 4000 Series, so the SR-4000 smart receiver can work with multiple transmitters on the same system. In addition to the included PIR-4000 motion sensor, you can add driveway sensors, beam sensors, or other 4000 Series transmitters and assign different tones or notifications for each zone.

This approach allows a single SR-4000 receiver to handle door and hallway motion alerts, driveway alerts, or outdoor approach alerts across a property, with each device using its own wireless channel and identification.

• Series: compatible with Dakota Alert 4000 Series transmitters.
• Multiple zones: supports pairing with multiple sensors for different entrances and areas.
• System growth: start with an entrance alert and expand to cover additional locations as needed.
