Door alarms, entry alerts, or entrance chimes send instant notifications when someone enters a monitored zone. Businesses, shops, and stores are used not only as a security precaution but also for customer service enhancement.

Entry alerts or door alarms are invaluable tools that allow businesses, shops, and stores to receive instant notifications whenever someone enters through a monitored zone. These devices serve a dual purpose as a security precaution and a means of enhancing customer service.

From a security standpoint, entry alerts effectively monitor and control access to a particular area. By setting up these devices at entrances, businesses can monitor who enters and exits their premises, deterring potential theft, vandalism, or unauthorized access. This helps protect valuable assets and promotes a safer environment for both staff and customers.

Moreover, entry alerts contribute significantly to enhancing customer service. When a chime or alert is triggered upon someone’s entrance, it immediately signals to the staff that a customer has arrived. This lets employees promptly acknowledge the customer’s presence, ensuring they are greeted with a warm welcome and prompt assistance. This efficient response leaves a positive impression on customers and helps businesses streamline their operations and improve overall customer satisfaction.

Furthermore, entry alerts can be customized to suit the unique needs of different businesses. They can be programmed to emit various chimes, tones, or even personalized messages, enabling establishments to create a distinct and welcoming atmosphere. For example, a high-end boutique may opt for a subtle and elegant chime, while a lively café might choose a more vibrant and energetic tone. Such customization adds a touch of personality to the business and contributes to creating a positive and memorable customer experience.

Additionally, entry alerts can be integrated with other security systems, such as video surveillance or access control systems, further bolstering the overall security measures. This integration gives businesses a comprehensive overview of their premises, enabling them to respond swiftly to potential security breaches or emergencies.

In conclusion, entry alerts or entrance chimes are indispensable tools for businesses, shops, and stores. They serve as effective security precautions, deterring potential threats and safeguarding valuable assets. Simultaneously, these devices enhance customer service by providing immediate notifications, ensuring prompt assistance, and creating a welcoming environment. With their ability to be tailored to individual business needs and integrated with other security systems, entry alerts are an essential investment for any organization looking to prioritize both security and customer satisfaction.

When to Use Motion Sensor-Based Door Alarms:

  • Use in hallways or when the door stays open (mall entrances, for example).
  • Use when metal doors or building materials may prevent magnetic door/window contacts from working correctly

When to Use Window/Door Contacts for Entry Alerts:

  • You want detection only when the door or window is opened
  • You don’t want any “motion-based” false alarms

Door Alarms (Entrance Alarms) detect when someone enters a door motion sensor monitored zone, a door opens, or when pressing a doorbell pushbutton. Most of our wireless products have a more extended range (from the sensor to the receiver) than products you might find at your local hardware store. This range is a necessity at warehouses, shops, stores, and over long distances. Need a strobe light, siren, or additional accessory for your kit?

At, we specialize in longer-range door alert products where system installation is accessible without requiring an election.

Choosing the Right Door Alarm for Your Door Alert Needs

Choosing a warehouse door alert chime for your business or home may seem daunting. We wrote a brief blog article to walk you through some criteria to consider when choosing your following business alert or home entrance alarm.

Common Uses of Entrance Alert Chimes
  • For office security, receive alerts when someone enters your facility. A Door Open Alarm is an excellent example of this use. A door and window alarm is triggered when the door or window is opened,
  • Store clerks receive a notification when a customer enters the store. This allows clerks to work in other areas of the store and immediately attend to customers when they enter the store, improving customer service.
  • Door Alarms for offices are great for warehouses to receive notifications when shipments arrive.
  • Used as a safety measure when children or people we care for enter or leave specific areas. An exit door leading to a swimming pool or spa is a good example.
  • A visitor is at the door. This is similar to a door chime for business or a door buzzer entry system used in an office building. Some products in this door alarm category may also function as wireless door chimes for business use.
Wireless Door Alert Transmitters
ERA-PIR Motion Over Door Entrance Alert for Stores

The transmitter is the device that contains the alert sensor. The sensors are either passive-infrared (triggered when it detects heat and movement) or magnetic-based (triggered when a metallic object passes through a monitored zone). Magnetically based sensors trigger when the magnetic contact between two pieces separates by opening a door or window. When a visitor passes through the sensor, it triggers the transmitter to send a wireless signal to the receiver.

Wireless Door Entry Alert Receivers

The receivers are either battery-powered or plug-in devices. These receivers “receive” the transmitted signal and emit a tone, a melody, or some audible sound to alert the user. Depending on the model, these receivers are packed with features. Many have a volume control knob or slider, external outputs for integration with other devices, and are typically expandable by adding more receivers to your kit.

ERA-VPRX Entry Alert Receiver for Entrance Alarm Kits
Common Uses of Entry Alert Chimes & Entrance Alarm Door Alarms

These products are versatile and used for security and improved customer service. For example, a doctor’s office may use a contact-based entry alert that attaches to the door and will alert staff when the door is opened. The nurse at the front desk does not want to be tethered to the front and may have errands to run. For obvious reasons, they do not want to lock the front door every time the nurse leaves his/her desk, so by installing an alert, the nurse will hear a chime sound when a visitor or patient opens the door. Customer service is another frequent use of a commercial entrance alert. The store in the mall has an entrance that’s always open. During slow operating times, the store clerk may need to go to the back to unpack the product or help a customer in the dressing room. A motion entrance alert is a great choice.

WDK-ERA-STROBE-ALERT Kit For Warehouses and Businesses

ERA-PRDCR by Safeguard Supply – a Motion Activated Entrance Alert Kit with Remote Receiver

The ERA-PRDCR has a motion sensor mounted above the entryway, and when someone enters, a gentle chime sounds from the receiver plugged into the back of the store.  Now, the clerk hears that someone has entered the store and can immediately come out to help the new customer. The kit is featured in this photo with an add-on accessory, a bright flashing strobe light that will add a visual notification.

EZ Chime Door Alarm, Door Alert by Safeguard Supply

The EZ Chime (EZ-Tone) is a small, self-contained alert mounted on a door. When the door opens, a small plunger hits a metallic plate, producing a tone sound. Ideal for commercial spaces under 2,000 sq ft., the product has been used by stores and businesses all over America. Motion Activated Entrance Alert and Entry Chimes receive an alert instantly when someone or something enters a space easier than you think. The entrance chimes on this page are motion-based, meaning they will detect any movement and generate a chime sound. If you have a door or window that typically remains shut, you may be interested in our door or window contact-based entry alerts. We recommend motion-based entrance chimes to avoid interference if you have doors or windows with a metallic frame.

Common Residential Applications for Door Alerts:

A common application for a door alarm is child safety!  Mount a window/door alarm sensor on the pool gate or patio door leading out to the pool.  When a child opens the gate, a wireless signal is sent to the plug-in receiver, alerting you that the door has been opened.  The system can also be expanded by adding additional battery-powered and plug-in receivers. If you have a swimming pool, most states require a warning device to alert the guardian when someone opens a door leading out to the pool.  Most parents want that additional peace of mind to know when a door opens to protect the security of their children and guests.

You may also place a window/door alarm on a cabinet where you store cleaning supplies.  The receiver plays a chime or alarm sound when a child opens the door. Many homeowners neglect to lock up the storage shed.  Place an outdoor-rated door/window sensor on the shed door.  If a user opens the door, an alarm or chime sound is played on the receiver.

Please call us if you are unsure which product is best for your unique application. Technically speaking, they are used to monitor egress (exits) through monitored areas. Using sensors, typically contact or movement-based, chimes or alarms notify the user that an exit was used. When you need an alert or alarm sound when someone exists through a monitored zone, the exit alarms category is the right place to find the product you need. Whether it’s the robust features of a panic bar that covers an emergency exit or a simple door/window contact to monitor an exit door, we offer a wide range of cost-effective and reliable products.

1800doorbell carries a large assortment of these products that are flexible and may be used in a variety of ways.  To make things better organized, products are grouped into specific categories, but as we explain below, these products have many uses.

Exit Alert Products
hs4317D Door Contact Alarm with Keypad

When these are used to open the door, an alarm sounds. An alternative to these products is the HS4317D Keypad Alert.  Using the supplied door/window contacts, this simple-to-install DIY product will emit a gentle chime or extremely loud alarm when an unauthorized door is opened.  The supplied key allows you to turn the alarm on and off.  

Sometimes, a user may want an exit notification but does not need a loud alarm to sound.  Some inexpensive but highly effective products are the HS4317D and HD4313 Exit Alarms.  These products all retail from $21-$44 and are easy to install. All three of these products work with door/window contact sensors.  When a monitored door or window is opened, an alarm sounds.  The alarm sound is silenced using a supplied key or a user-programmed code.

Typical Uses of Our Door Exit Alerts

  • Businesses like using the HS4317D and HS4313 to monitor sensitive areas like supply and utility closets in apartment complexes, gas stations, or office spaces.  This will notify the manager of unauthorized access to a closet and deter anyone trying to access the area. The manager uses the supplied key or punches in a code for authorized access.  When the door is opened, the alert does not sound.
  • Most commercial locations must maintain exits for emergencies such as fires. Visitors must be able to exit the facility quickly without needing a key. The challenge is that they want to keep the door locked so people cannot enter from the outside. Products like the Alarm 250 and Alarm 700 by Alarm Lock allow you to do just that. In an emergency, users push the bar or paddle, which unlocks the door for a quick exit.
