Description
Indoor Motion Entrance Alert Kit for Business and Commercial Use
The ERA-PRDCR motion entrance alert kit combines the ERA-PIR motion sensor transmitter with the ERA-DCRX multi-zone receiver to create a long-range wireless entrance alert system. The kit is designed for doors, interior passages, and open areas where it is important to know when someone has entered or moved through a monitored space. With a wireless range rated up to 4,000 feet in line-of-sight conditions, the sensor and receiver can be separated by significant distance while still maintaining communication.
In this configuration, the ERA-PIR is installed at the entrance or area to be monitored, and the ERA-DCRX is placed where staff can hear and see the alerts—often at a service counter, office, or back room. When a person passes through the sensor’s coverage area, the receiver plays a selected tone for a few seconds and can also operate low-voltage outputs or a relay for connected equipment.
ERA-PIR Passive Infrared Motion Sensor Transmitter
The ERA-PIR is an indoor passive infrared (PIR) motion sensor that detects the combination of heat and movement as people walk through its monitored zone. When motion is detected, the sensor’s built-in transmitter sends a radio signal to the ERA-DCRX receiver. The transmission range is rated up to 4,000 feet in line-of-sight conditions, allowing the sensor and receiver to be located in different parts of a building or even separate buildings on the same property, as long as the path is within range and not overly obstructed.
The ERA-PIR features an adjustable monitoring pattern so the coverage width and depth can be matched to the entrance or hallway being protected. Typical use is to mount the sensor above or beside a doorway so that people walk through the detection field when they enter. The sensor is powered by a 9V alkaline battery and includes a test button for programming and verification.
- Detection method: indoor passive infrared sensing for people moving through the monitored zone.
- Transmission range: up to 4,000 ft line-of-sight to compatible ERA receivers.
- Power source: 9V alkaline battery.
- Typical coverage: adjustable monitoring area suitable for standard doorways and interior corridors.
- Mounting options: wall or ceiling near entrances, aisles, or open areas.
- Compatibility: works with ERA-DCRX and other ERA Series receivers.
Placement and Setup of the ERA-PIR Entrance Sensor
For entrance alert applications, the ERA-PIR is commonly mounted above the inside of a door or on the wall adjacent to the doorway, angled so that people pass through the detection pattern as they enter or exit. Mounting height is chosen to provide a clear view of the area without obstruction from door frames, shelving, or signage. The sensor’s coverage can be adjusted to narrow or widen the monitored zone, which helps avoid triggering on movement outside the intended path.
During setup, the installer pairs the ERA-PIR with the ERA-DCRX by placing the receiver into programming mode, then triggering the sensor either by walking through the field of view or pressing the built-in test button. After pairing, a melody is selected for the zone that the sensor is assigned to, allowing the entrance alert tone to be distinguished from alerts from other transmitters in the system.
- Typical mounting locations: above entry doors, at hallway openings, or overlooking interior aisles.
- Orientation: aim across the walking path rather than directly at it for more reliable motion detection.
- Programming: pairs to a specific zone on the ERA-DCRX and can be assigned a unique melody.
ERA-DCRX Multi-Zone Receiver with Outputs
The ERA-DCRX is a desktop or wall-mountable receiver designed for commercial and business environments. It supports four programmable zones, with each zone able to handle multiple ERA transmitters. When a programmed transmitter such as the ERA-PIR activates, the receiver plays the tone assigned to that zone and indicates which zone was triggered using its indicator lights.
The ERA-DCRX offers twelve selectable melodies and four volume levels, with the maximum volume reaching approximately 85–90 dB. This allows the entrance alert to be heard over typical background noise in shops, offices, and warehouses. The receiver is powered by a 12V DC adapter and is designed to sit on a desk or counter or be mounted on a wall as needed.
- Zones: 4 programmable zones for organizing transmitters by area.
- Melodies: 12 tones that can be assigned per zone.
- Volume: four levels with a maximum around 85–90 dB.
- Power: 12V DC plug-in power adapter.
- Wireless range: up to 4,000 ft line-of-sight to ERA transmitters.
- Receiver capacity: supports up to 12 transmitters or sensors in total, with multiple per zone.
12VDC Outputs and C‑FORM Relay for External Devices
One of the distinguishing features of the ERA-DCRX receiver is its set of low-voltage outputs and a C‑FORM relay that can be used to integrate external devices. Each of the four zones has its own 12V DC output that can be configured to activate when a transmitter on that zone is triggered. This output can drive compatible accessories such as small strobes, bells, or buzzers within the rated current limits.
In addition to the zone outputs, the receiver includes a single C‑FORM (changeover) relay that can be assigned to one or more zones. The relay can be wired to an external system that requires a dry contact input, such as a larger alarm panel, automation controller, or other signaling equipment. The duration of the relay activation can be matched to the programmed 12V output time (for example, 5 seconds, 10 seconds, 1 minute, or 2 minutes) depending on the configuration.
- Zone outputs: four 12V DC outputs, one per zone, for low-voltage accessories.
- Relay: one C‑FORM relay assignable to one or multiple zones.
- Output duration: selectable activation time (commonly 5 seconds to 2 minutes) tied to zone settings.
- Integration examples: strobes, external sounders, building systems, or dialers that react to an entrance alert.
How the ERA-PRDCR Entrance Alert Kit Functions
In daily use, the ERA-PIR watches for movement at an entrance or interior passage, while the ERA-DCRX sits where staff can hear and see its alerts. When someone enters the monitored area, the motion sensor transmits to the receiver. The receiver then plays the melody associated with that sensor’s zone and, if configured, activates the corresponding 12V output and relay.
Because the receiver supports four zones and multiple transmitters per zone, the ERA-PRDCR kit can be the foundation of a larger entrance alert system. Additional ERA-PIR sensors, door contact transmitters, push buttons, or driveway sensors can be added in other areas, each with its own tone and zone indicator. This allows users to tell at a glance—and by sound—whether motion came from the front door, back hallway, warehouse entrance, or another monitored location.
- Alert path: motion at entrance triggers sound and indicator lights on the ERA-DCRX, plus optional 12V/relay outputs.
- Multi-zone capability: up to four zones, each with individual tone and output options.
- Scalability: supports multiple transmitters and can be combined with additional ERA receivers if needed.
ERA Series Compatibility and Expansion
Both the ERA-PIR and ERA-DCRX are part of the Safeguard Supply ERA Series. The ERA-PIR can also be paired with other ERA receivers such as plug-in units or portable receivers that may be added later, and the ERA-DCRX can be programmed to work with other ERA transmitters beyond the included motion sensor. There is no fixed limit to the number of ERA-DCRX receivers that can listen to a single ERA-PIR, so the same motion event can be heard at several locations by adding more receivers.
This compatibility allows the ERA-PRDCR to fit into a larger system that may include entrance alerts, driveway alerts, doorbells, and other wireless signaling devices, all sharing the same 4,000-foot wireless platform.
- Series: Safeguard Supply ERA long-range wireless system.
- Compatible transmitters: ERA-PIR and other ERA sensors and push buttons.
- Compatible receivers: ERA-DCRX plus additional ERA receivers added as separate components.
