GENERAL DESCRIPTION 

EK-WL8-HS/AU  is  a  wireless  2-in-1  device 
equipped with a heat detector and a sounder. 

The device analyzes physical factors associated 
with  fire  and  the  way  these  factors  change 
through time. An alarm signal is generated when 
the air temperature exceeds a threshold value or 
starts  rising  at  a  certain  speed.  The  signal 
travels  through  repeaters  to  the  translator 
module  which  then  informs  the  main  control 
about the emergency.  

The thermal sensor is A1R type. 

The device is supplied with a mounting kit. 

The  product  complies  with  the  requirements  of  the  AS  ISO  7240.5  and  AS  ISO 
7240.25 standards. 

FEATURES

Bi-directional wireless communication

Intelligent algorithms

Sound synchronization with other sounders in the system

Tamper switch

10-year battery life

Self-optimizing wireless frequency and amplitude algorithms
