We won the project against some excellent competition. We were tasked with the upgrade of the existing system to a fully compliant Voice Alarm system.
We designed the 6 zone system around the SigNET LS a highly sophisticated and effective voice alarm, public address and background music system ideal for use in large or complex sites.
At the heart of the system is a distributed matrix connected to a high-speed data network that allows the amplifiers, fire alarm interface(s), audio inputs, and manual and automatic controllers to be distributed around the site or for the whole system to be located centrally.
The network utilises digitally stored messages resulting in the intelligibility, clarity and audibility critical for life safety systems. Messages suffer no interference or degradation over long distances, even when many buildings are linked on one network.
Dual data-communication rings ensure the system continues to transmit signals and messages to every other part of the network in the event of a catastrophic failure at any one point and sophisticated disaster recovery cause and effects can be easily planned into the system.
The modular all-master design of the system means that where a site is intended to expand in future, the minimum of equipment can be installed initially and then added to later. Significant financial savings are possible because equipment amplifiers and loudspeakers can be retained and reused as changes take place. Furthermore, the system allows VA, PA and BGM to be cost-effectively integrated into one system.
The system’s software allows rapid system re-configuration with the minimum of downtime, fault conditions can be observed on a PC screen and configuration alterations made whilst the site records are to hand.
SS2N network stations are the centre of a SigNET LS network, controlling data transmission and inserting/extracting audio, control and status data to the communication rings. Internal processors continually check the SS2N’s status and report changes to all other stations on the network. Each network station includes the following ports and connections:-
