SECURITY ALARM SYSTEM SETUP

Sensors, Devices & Wiring
Setting up your security alarm system is the final step after installation. This process involves:

  1. Configuring sensors and control panels.
  2. Measuring electrical parameters for wiring and power supply.
  3. Conducting a full system functionality check.

While there are general guidelines for this process, the specific steps can vary depending on your system and setup. Below, we’ll break down each stage with practical examples to help you get it right.


CONFIGURING DEVICES AND SENSORS

How you configure your system depends on its complexity and the types of equipment you’re using.

  • Non-addressable sensors (with relay outputs): These are plug-and-play. If connected properly, they start working immediately.
  • Addressable sensors: These need a unique network ID for operation within the system.

The control panel (or receiver) usually requires more attention:

  • For addressable or wireless devices, you’ll need to register all installed sensors in the control panel’s memory.
  • You’ll also need to configure relay controls, indicator devices, and arm/disarm procedures.

For GSM systems, program the phone numbers to send alerts. If your system connects to a monitoring center, enter the appropriate IP addresses during setup.

In short, the scope of work depends on the specifications in your installation plan and the level of security required for the site.


MEASURING ELECTRICAL PARAMETERS

This step is primarily for wired systems, and not all parameters are always checked in practice. However, it’s a good idea to perform these measurements for optimal system performance.

  1. Insulation Resistance Testing
    This test involves applying high voltage to the circuit. However, it can damage connected sensors, so it's rarely performed in practice.

  2. Wiring Resistance Measurement
    This is more critical. Test the resistance of the circuit, excluding the end-of-line resistor.

  • Check wires and relay contacts.
  • The resistance value should not exceed 1 kΩ to avoid system malfunctions, such as false alarms or failure to arm.
  1. Voltage Measurement
    While not always required, checking the voltage can help diagnose issues like power drops at wire junctions, which could cause system failures.

SYSTEM FUNCTIONALITY CHECK

Once setup is complete, power up the system and test:

  1. Sensor activation (e.g., motion detectors, glass break sensors).
  2. Coverage zones (for motion detectors).
  3. Notification triggers outlined in the design plan.
  4. Signal transmission to remote devices (for monitored systems).

If all tests are successful, your alarm system is ready to go. A completion report is typically generated to document this.


BOTTOM LINE

Proper setup and testing ensure your security alarm system operates reliably and meets U.S. safety standards. Whether you’re installing a system for a small home or a commercial property, taking the time to configure and test it thoroughly pays off in the long run.
