1.4 IMPORTANT NOTES TO BE CONSIDERED BEFORE INSTALLATION
Prior to installation refer to and follow applicable local standards and national codes of practice
for guidance on location and spacing of sensors and general system requirements.
Check compatibility of your control panel with the wireless Ekho system protocol and operating
procedures.
1.5 TECHNICAL SPECIFICATIONS OF THE SYSTEM
Before installing the system the following points need to be considered.
There is a maximum number of devices that can be connected wirelessly to the translator
The communication range between the translator, expanders and all wireless devices is
specified in ‘free air’. The range will vary and generally decrease when installed within
building structures.
The translator is connected to a control panel through a wired loop: Check the maximum
loop length and current limitations of the control panel.
It is recommended the preliminary system design is made on paper. Optimum device
positioning can be verified during installation and additional expanders can be added if
required.
The number of translators / expanders required is determined by the number of wireless
devices connected to the control panel and the communication range between the
translators / expanders and wireless devices.
The following table shows the maximum number of devices that may be connected to a translator
/ expander and the communication distances in ‘free air’.
