IntroductionOne 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 PanelPrior 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 DetectorCommon 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 DetectorIn 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.
