Seco-Larm E-931CS22RFCQ Wireless Reflector Beam Entry Alert Door Chime. No Batteries, Wired Entry Alert

What is a Wireless Break Beam Sensor Alert Kit?

The BALERT entrance alert kit has been around for as long as I can remember. It's a very popular product because it's a simple, but effective way to monitor a door or hallway. In many cases, customers who liked the functionality of the BALERT didn't purchase the product because it was wired...from the emitter box to the speaker.

Now, we have a wireless version of the BALERT, which is the BALERT-W ("W" for Wireless) is the Seco-Larm E-931CS22RFCQ. You get the same reliability of the photo beam reflector-based product with the added benefit of a wireless transmission from the emitter to the speaker.

Here's how this break beam sensor-based kit works:

The BALERT-W is the Seco-Larm E-931CS22RFCQ. The kit comes with three (3) main components: a sensor that emits an invisible beam to a reflector, a reflector, and a wireless speaker.  To understand how the product works we will use a common doorway as the area we want to monitor.  On one side of the door, we will mount the wireless sensor (plugs into a standard wall outlet) and on the other side of the door, we will mount the reflector.  The sensor will send an invisible beam to the reflector.  As long as that beam is reflected in the sensor the system is silent.  When that beam is broken, which means the beam has not reflected to the sensor, the sensor is triggered and it then sends a wireless signal to the speaker (speaker plugs into a standard wall outlet).

Here's what's in the BALERT-W (Seco-Larm E-931CS22RFCQ) Kit:

• Waterproof reflective sensor (transmitter)
• Wireless Speaker
• Reflector
• Two power adapters (one for sensor, one for speaker)
• Three mounting brackets
• Optional Wall Mount Bracket is available for separate purchase

Break Beam Kit Features:

• Max distance from the sensor to the reflector is 22 ft.
• Wireless range, from the sensor to the speaker is "up to" 328 ft. (100 m).  Please note, this is a line of sight range.  Building materials will interfere and possibly reduce the range
• Speaker and sensor are powered by included plug-in transformers
• Adjustable volume on speaker up to 90 dB
• Sensor and reflector are outdoor rated 32 F - 122 F
• Sensor can pair with an unlimited number of speakers
• Speaker can pair with up to 5 sensors
• Speaker will make a chime or ALARM sound
• Alarm output duration is 3-30 seconds

We would also recommend two other choices:

• The ERA-PIR-SPK kit is a passive infrared sensor typically mounted over the door.  When a visitor passes through the zone, the speaker inside the sensor plays a chime sound.
• The EZ CHIME - a purely mechanical entrance alert.
