WARNINGS & LIMITATIONS

Devices use high quality electronic components and plastic materials that are highly

resistant to environmental deterioration. However, after 10 years continuous

operation it is advisable to replace them to reduce the risk of reduced performance

caused by external factors. Ensure the devices are only used with compatible control

panels. Detection systems must be checked, serviced and maintained on a regular

basis to confirm correct operation.

Refer to and follow National Codes of Practice and other internationally recognized

fire engineering standards. Appropriate Risk Assessment should be carried out

initially to determine correct design criteria and updated periodically.
