For a project where a ‘wire-free’ solution is needed, a staged approach is employed. Firstly, it is essential to carry out a radio survey to understand the radio profile of the building and plan where devices need to be fitted. Secondly, a proposal listing the type of equipment will be offered. Prior to the fitting process a detailed scheme layout will be provided with the equipment list to aid the installer. On completion, commissioning of the system is a standard part of the package.

Applications:

The system is suited to parts of buildings, which have sensitive structures and decoration, or which cannot be disturbed for historic or preservation reasons. Wire free equipment is also useful to extend an existing system (temporarily or permanently), such as in portable buildings in an educational complex.

Benefits & features:

• Design capacity: Five interfaces per analogue loop

• Loading per interface: Up to 15 devices

• Operating radio frequency band: 868mHz

• Integrity: the devices are selfmonitoring

• Addressing: Devices are addressed individually via an onboard mechanical card facility

• The ‘detection and alarm set’ is an annex to an analogue loop system, without the need for a costly dedicated control panel

• Ease of installation: Installation and setup can be accomplished without complicated procedures
