The Exit Stopper alarms have been installed on our emergency exit doors of our medium sized pharmaceutical production plant in the UAE in Jabel Ali some 20 odd miles outside Dubai.
These doors can be opened from inside with just one press and push of the bar handle and the purpose is for easy escape in case of fire or any kind of emergency.
In case of an opened door we wanted to know where, to take immediate counter action and to avoid outside contamination entering the plant or corridors. This is mainly to avoid someone from production opening the exit doors unnecessarily.
We picked you up as a supplier through the Google search engine â€œfire alarm doorsâ€ and found a good product description with all details and good value for money.
Thank you for your efforts. Until today no one has dared to open the door again knowing that a â€œbig noiseâ€ is expected!!
