1 DESIGNING AND INSTALLING THE SYSTEM
1.1 INTRODUCTION
The aim of this document is to explain how to install the Ekho wireless fire system.
All the data detailed is only to be used with the Ekho wireless devices that use the Ekho wireless
communication protocol for communication.
1.2 WIRELESS DEVICES: A GENERAL DESCRIPTION
A wireless fire alarm system can be composed of a combination of the following wireless devices:
Wireless translator:
this device is the core of the wireless system; it communicates continuously
with other wireless devices, such as sensors, call points, sounders, etc.
The translator also communicates with the control panel of a fire alarm system.
This device communicates with the control panel through the ESP loop and with all wireless
devices via a radio frequency.
The whole system is controlled via a control panel similar to any other fire alarm system; the
translator is the interpreter that holds exclusive rights of communication with the wireless devices
and makes possible the communication between the control panel and the radio devices: this is
why this device is called a translator.
The wireless system general configuration, created by the installer, is stored in this device.
Wireless expanders:
The translator communicates with other wireless devices only if they are
in a certain range or if communication is not blocked by walls and other obstacles. When wireless
area coverage needs to be expanded and/or the environment poses difficulties to radio
communication, one or more wireless expanders can be used; these devices act as repeating
devices for communication between wireless devices and the translator.
Sensors:
these devices are designed to detect smoke and/or heat in the environment. If heat
and/or smoke is present and exceed a defined limit, the wireless system triggers an alarm
condition.
Call points:
These devices provide a manual method for initiating a fire alarm condition.
Sounders:
these devices play an audible warning when the wireless fire alarm system is
activated.
Voice annunciators:
In the event of an alarm, voice annunciators broadcast pre-recorded alarm
voice messages.
Input modules:
receive a signal from wired conventional devices and transmit them to the
translator.
