What our Clients say

“ASL are the David that can conquer any Goliath sized task. I would have no hesitation recommending ASL.

I am extremely pleased with ASL’s delivery of the Passenger Announcement/Passenger Information Display (PA/PIDS) for Malaysia’s first fully driverless Metro system in Kuala Lumpur, the Sungai Buloh to Kajang (SBK) Line.  ASL’s team have worked tirelessly with our Project Delivery Partner (MMC/Gamuda) and the Owner (MRT Corp) in developing the PA/PIDS solution. I would have no hesitation recommending ASL as a solution provider with their innovative solutions approach and responsiveness to the Client.”

Tom Khella – KVMRT Project Kuala Lumpur Malaysia

“We have been working together for 14 years and I must say it’s been one of the most enjoyable working relationships of my career at FoneAlarm. You have without hesitation, provided support for all the systems we have installed on behalf of our clients and we have over the years built a trusting and professional relationship, with lots of ‘first’s’ along the way.
We, FoneAlarm and our customers benefit from this relationship, the reliability of your PA systems and the outstanding service all my staff receives from your support personnel is second to none.
This is something we have benefited from on the 8 station installation project we have just completed with Southeastern.
You are the supplier of choice for the vast majority of our customers and I believe this is a reflection on both the product and the service you provide.
I think the most memorable for me was the commissioning of the PAVA system with your staff at Kings Cross mainline, a very long night but very rewarding.”
