Wire Free Installation Hints and Tips

Notes on Wire Free detector location:

The Ademco Microtech 5800 range of wire free detectors can run at indoor ranges of

up to 60 meters from the receiver. However, there are many factors which can affect

this.

1. Metal objects can significantly attenuate the signals coming from wire free

detectors. Care should be taken to ensure that no metal cladding, cabling,

mirrors or pipes are near any detector or receiver, or in the straight line path

between the detector and the receiver.

2. Thick walls between the detector and receiver can reduce the signal strength.

Radio signals can pass easily through plaster board walls and wood panelling,

and slightly less well through brick. Thick stone walls will reduce the signals

significantly. This should be taken into account when planning the

location of detectors and receivers.

3. Sources of local radio interference could make reliable operation of a wire

free alarm system impossible. For example, the close proximity of a cell phone

mast, a taxi operator’s base station or heavy electrical equipment will give very

strong radio interference.

All the above factors should be taken into account when planning the installation of a

wire free alarm system. Remember that there will be some sites where wire free

systems are impractical due to one or more of the above factors causing insurmount-

able problems.

If the above guidelines are followed the Accord xpC and the 5800 detectors will give

many years of reliable operation.

Site Surveying

Before applying wire free installation, it is strongly advised that the proposed site is

properly surveyed using the Ademco Microtech survey kit, (Part No. 2021-026).

Walk Test

When walk testing zones, the RF receiver is automatically placed in a reduced sensi-

tivity mode to simulate a worst case scenario for the RF detectors. When leaving

programming mode, always walk test RF detectors to check and re-synchronise the

detectors with the panel.
