protected area, the pattern of the sound waves changes, signaling the alarm center to sound the alarm.

•Infrared — Work like ultrasonic motion detectors, except that they use invisible infrared light instead of high-frequency sound to detect motion.

•Microwave — Work like ultrasonic motion detectors, except that they use radio waves instead of high-fre- quency sound to detect motion.

Some motion detectors have a built-in alarm sounder and can be connected directly to an alarm siren or other sound- ing device.

If the type of motion detector you select has tamper protec- tion, you might need six-conductor hook-up wire to connect it to the alarm center. Otherwise, you need four-conductor hook-up wire to connect motion detectors.

Panic Buttons and Tamper Switches — Are normally- open types of sensors. A panic button lets you sound the alarm at any time, even if the alarm center is not armed. A tamper switch instantly sounds the alarm if someone tries to open the secured object. You can mount these switches on the alarm center, a gun cabinet, or anywhere you want the alarm to instantly sound if you press the switch or someone tampers with it.

Pre-Alarm Buzzer — When the alarm system is armed and a delayed zone is activated, the alarm center activates a pre-alarm for the amount of time you set (see “Setting the Entry and Exit Delay” on Page 17). After that delay time elapses, the alarm system sounds the alarm siren and other connected security equipment. When the battery is low, the pre-alarm sounds for 5 seconds per minute. To hear the pre- alarm, you must connect a small sounding device such as a piezo buzzer to the alarm center.

Mount the device where you can hear it during the entry de- lay. Do not mount it on or near the alarm center. The sound might lead an intruder to find the alarm center and possible disable the systems.

Alarm Siren — When a sensor is activated and the system is armed (or the panic/tamper zone is violated), the system can activate an alarm siren connected to the alarm center.

Mount the siren outside your home where you, your neigh- bors, and the police can hear it. If you mount it in an area that is not protected by the alarm system (such as an out- side eave), mount it inside a siren enclosure to discourage tampering.

Security Strobe — When a sensor is activated and the sys- tem is armed (or the panic/tamper zone is violated), the sys- tem can activate a security strobe or other types of lights connected to the alarm center.

Note: You can connect a security strobe to the same out- puts on the alarm center as you use for the alarm siren. For more information, see “Connecting a Siren and/or Lights” on Page 14.

When deciding where to install a security strobe, choose a location outside your home where the strobe’s light is highly visible.

Automatic Telephone Dialer

For a higher level of security, you can connect an automatic telephone dialer to your alarm system. We recommend RadioShack Cat. No. 49-434 (available at your local RadioShack store).

An automatic telephone dialer connects to your phone line and automatically calls one or more preset phone numbers if the alarm sounds.

Note: Many automatic telephone dialers can use the alarm system’s battery power to dial numbers if AC power is disconnected.

When deciding where to install an automatic telephone dial- er, select a location that is:

•Near a phone jack

•Near an AC outlet

•Not easily accessible to an intruder

Cautions:

•If you connect an automatic telephone dialer to your sys- tem and want to program it to call your local police department, check with them first. Some police depart- ments do not accept calls from automatic telephone dial- ers. If your police department does not accept calls from automatic dialing equipment, you can program it to call a friend or private security service who can notify the police department, if necessary.

•Some automatic telephone dialers deliver a prerecorded voice message to the desired number when activated, while others transmit an electronic signal to a private security service. In most cases, private security services charge a fee to accept calls from automatic dialing equipment. For more information, call the police depart- ment and private security services in your area.

Two-Zone Burglar Alarm System specifications

The Radio Shack Two-Zone Burglar Alarm System is designed to provide homeowners and small business owners with effective security solutions. This system offers an excellent balance of functionality, reliability, and affordability, making it a popular choice for those looking to enhance their property's safety.

One of the standout features of the Radio Shack Two-Zone Burglar Alarm System is its dual-zone capability. This allows users to monitor multiple areas of their property separately. For example, one zone can be designated for exterior doors, while another can monitor interior spaces, which can help to prevent false alarms triggered by pets or other movements within the home. This feature is particularly useful for larger properties that require more than just a single-point monitoring system.

The system is equipped with multiple sensors, including door and window contacts, which can easily be installed to ensure comprehensive coverage. These sensors are designed to detect unauthorized entry and trigger the alarm whenever a door or window is opened. The system also includes passive infrared motion sensors that can identify movement within a designated area, adding an additional layer of security against intruders.

In terms of technologies, the Radio Shack Two-Zone Burglar Alarm System utilizes a microprocessor-controlled control panel, which is at the heart of the system's operations. This logic board processes signals from all connected sensors and determines when to trigger the alarm. The system can provide alerts via a loud siren, while also allowing for notifications to be sent to the owner’s smartphone or other devices, depending on the model.

The installation process for the Radio Shack burglar alarm system is user-friendly, designed for ease even for those who may not be technically savvy. The system typically includes clear instructions and mounting hardware, making setup straightforward. Users can customize their alarm system according to their specific needs and property layout, which further enhances usability.

Another important characteristic of the Radio Shack Two-Zone Burglar Alarm System is the option for battery backup. This ensures that the alarm continues to operate even during power outages, allowing for uninterrupted security coverage. Moreover, the system is frequently praised for its durability and resistance to environmental factors, making it a robust choice for various settings.

Overall, the Radio Shack Two-Zone Burglar Alarm System represents a practical and efficient security solution, combining essential features, advanced technology, and user-friendly installation, all designed to meet the security needs of modern users.
