The ERA-PRDCR is a long range, motion activated entrance alert kit by Safeguard Supply. The transmitter (ERA-PIR) has a Passive Infrared Sensor (PIR) that is triggered when motion and movement are detected in the monitored zone. When the sensor is triggered, it transmits a wireless signal up to 4,000 to the ERA-DCRX plug-in receiver.
This type of sensor works best in situations when a door may sometimes stay open or you need to monitor an open area or hallway. Most users will mount this sensor over a door and angle the lens down towards the floor to pick up visitors through the emitted zone. The companion product to this sensor is the ERA-UTX with is sensor/transmitter that can function as a push button and/or a magnetic door contact. Both sensors are compatible with the ERA-DCRX, which is the receiver featured in this kit.
The ERA-DCRX Receiver:
The receiver plugs into a standard wall outlet and may be located up to 4,000 ft. from the transmitter. This is line-of-sight range which means environmental factors may reduce the range. The kit ships with one receiver, and add-on receivers are available (ERA-DCRX) to allow you to expand the kit through out other areas of your facility. For example, many customers will place a receiver in the warehouse or shop, and another receiver in the front office.
Each receiver has four zones, where each zone will play 1 of 12 selected melodies to play when a sensor/transmitter paired with that zone is triggered. Each zone can pair with 3 different transmitter./sensors. The receiver also features a volume control button which toggles the sound to four different levels, a mute, and will turn the unit on/off. Each zone mentioned above also features a live 12 VDC output with multiple duration settings, that will power an external device. Common uses of this 12V DC output is a strobe light, siren, strobe-siren combo, etc. For example, in a loud environment like a garage or machine shop, users often connect a Mini-Strobe/Siren that flashes a bright strobe and plays a loud 115 dB siren when triggered.
The receiver also features 1 x C-Form relay that allows the unit to integrate with other devices. There are countless numbers of ways to integrate the receiver with other products. One use, for example, might be to connect the relay on the receiver to a guard gate, for example, to trigger the gate to open when the receiver is triggered.
- Receiver ships with a plug-in 12V transformer to power the unit (plugs into a standard wall outlet).
- Features a volume control knob for 4 x sound levels, a mute, and on/off.
- Four zones on the receiver, with each zone playing one of twelve melodies. Each zone features a small LED that flashes red when triggered.
- Receiver has 12 melodies to choose from.
- Each zone features 1 x 12V DC output with a duration setting of 5 sec, 10 sec, 1 minute, and 2 minutes.
- 1 x C-Form relay.
- Sound level is 80 dB – 90 dB on highest setting depending on melody selected.
- Receiver may be located up to 4,000 ft. from transmitters.
- Receiver can pair with 12 transmitters (3 per zone).
- One year manufacturer’s warranty.
- Manufactured by Safeguard Supply.
The ERA-PIR Transmitter:
The ERA-PIR transmitter uses a passive-infrared sensor to detect motion in the monitored zone. The sensor ships with an aluminum mounting bracket that allows the user to rotate the angle of the emitted monitored zone. The beam is designed to emit a wide, but narrow zone to easily manipulate the size/area of the monitored zone the user would like to create. The higher the sensor is mounted, the larger the zone becomes. The table below approximates the area based on the mounted height:
Couple with the mounting height, adjustments of the angle also allows more manipulation of the zone. The image below illustrates how you can adjust the angle.
- Transmitter may be mounted up to 4000 ft. from the compatible receiver (ERA-DCRX).
- Sensor is passive infrared (PIR).
- Transmitter/sensor is powered by 1 x 9V Alkaline battery (not included.) Battery should last 1-2 years, depending on usage.
- When battery level is low, the red led light on the receiver will flash for 10 minutes when triggered to notify the battery level is low. In addition, the melody will play 2 x (twice) when triggered.
- Transmitter ships with mounting bracket and mounting screws.
- One year manufacturer’s warranty.
- Manufactured by Safeguard Supply.
