Hardwire/Wireless--The Pro's & Cons


Examining a Hardwire system: The Pro's and Con's

Let's examine the Pro's and the Con's of a hardwired system and what benefits and draw backs they might have. In a hardwire system all sensors and zones are returned to the control panel by wires. This includes the sirens, keypads, motion detectors, smoke and gas detectors and all window and door contacts.

The Pro's of a Hardwired system are as follows:

• Easier to maintain and troubleshoot problems.

• You do not have to be concerned with changing batteries.

• Your zone is continually supervised for faults through end of line resistors.

• You may generally use detectors and sensors from any manufacturer.

• Hardwire detectors and sensors are generally smaller and less expensive.

• You do not have to be concerned with radio interference or distance from panel.

• More difficult for burglars and intruders to disable the system.

The Con's of Hardwired system are as follows:

• It is more difficult to install in pre-existing construction.

• It takes much more time to complete installation of the alarm system.

• It is difficult to always hide wires for safety and aesthetic reasons.

• If you rent a home or apartment, you probably will not be allowed to hardwire.

• It is more difficult to add additional sensors at a later time.

Examining the Wireless systems: The Pro's and Con's

Let's now examine the Pro's and Con's of a wireless system and what benefits and draw backs they might have. In a wireless system all devices are connected back to the control panel via radio signals and small transmitters and receivers with no external wiring involved. The exception being the transformer, keypad and outside sirens. There are models that are completely self contained.

The Pro's of a Wireless system are as follows:

• These systems are easier to install in pre-existing construction.

• No external wiring to fish through walls or attics.

• Ideal for renters or apartment dwellers.

• Wireless system is very portable. It is as easy to take it down as it is to set it up.

• Easiest to add additional detectors or zones to the existing system.

The Con's of a Wireless system are as follows:

• Wireless devices are large and very conspicuous on windows and doors.

• The transmitters have batteries that have to be checked and changed periodically.

• Wireless devices are brand specific. Must match manufacturers of control panel.

• Wireless devices are more expensive than hardwired devices.

• Wireless devices do not have constant contact with the panel. (Supervision limited).

In reality you will probably end up with a combination of the two methods. It is my opinion that you should make every effort to go hardwired whenever possible. I base this opinion on years of experience, as a Law Enforcement officer, investigating alarm calls and noting which systems were the most reliable. This is not to say that wireless does not have a real place in the alarm world, but it is hard to beat the reliability and cost of the hardwired system. Most of today's alarm panels allow you to combine hardwire with wireless, giving you the best of both worlds.
