How to Add Hard-wired detectors to a Wirefree Alarm System


One of the negatives in using wirefree Security Systems is the poor range of detectors available. With hard-wired alarms , sensors are usually compatible and just about any detector could be attached to just about any control panel. For instance, say you need a roller shutter magnetic contact fittig to a garage door but signalled to your already fitted wirefree alarm. None of the major wireless alarm manufacturers have a wireless roller shutter contact: as a result,  a hard-wired detector will have to be used.

A lot of wirefree control Panels have one or more hard-wired zones for connecting hard-wired detectors. This enables you to connect a new detector to the control panel using multicore wire.

However for neatness you can connect the detector wirelessly.

The methods are described below.

Connecting a new Detector to the wirefree control Panel

Prior to using this method, check that there's one or more hard-wired input in the wirefree control panel. If the hard-wired detector needs electrical power (e. g. PIRs, Break-glass), and then check to see if an auxiliary power supply can be found in the control panel. When a power supply in the control panel isn't available, then the detector will have to be run off a battery or possibly a 12v power supply.

Wirelessly Linking a new Non-Powered Detector

Common non-powered sensors are typically products just like magnetic contacts and PA Devices. These can be wired directly to a wireless transmitter which is compatible with the existing system. Using the Visonic Powermax range of wirefree alarms, there are a pair of wirefree transmitters we can use. This MCT-100 is a battery-operated transmitter and contains 2 hard-wired inputs and also 2 wirefree outputs. each output van be learnt to a wirefree zone on the control panel. 
Additionally the MCT-302 magnetic contact incorporates 1 hard-wired input which can be used to connect a hard-wired detector.

Wirelessly Linking a new Powered Detector

In order to use a powered detector wirelessly, a battery or local power supply is needed to power the detector.

The example above uses the Powermax equipment but most major alarm manufacturers have similar equipment.

How Good are Wireless Burglar Alarms?

Professional-Quality versus DIY-Quality

Not all wireless burglar alarms are created equal.

Professional-quality wireless alarm systems, i.e. those used by professional installation companies, are very reliable.  Wireless alarms can never be as reliable as hard-wired systems and can not be installed to better than security grade 2.  For an explanation of alarm security grades read the article Burglar Alarm Security Grades.

How Good are Visonic K9-85 Pet Friendly PIRs

Using Passive Infra-red (PIR) detectors in the presence of animals is always a compromise!

Visonic produce two general purpose wireless PIRs for use with the Powermax Wireless alarm system.  one is labelled NEXT MCW and the other is labelled NEXT K9-85.  The latter is promoted as being suitable for use where animals up to 85 lbs in weight are present.

Ten Tips For Installing A Wireless Burglar Alarm System


In order to make the most of your wireless alarm system consider the following.
  1. Choose an alarm system that operates on the dedicated narrow band wireless alarm frequency (868 MHz).  This will ensure that the system is not easily blocked or jammed by overcrowding.
  2. Make sure that the system you choose is 2-way.  Some cheaper systems are 1-way and will not interrogate the devices on the system.  A 2-way system will report on the condition of the batteries and the status of the system.
