Designed and manufactured to the highest standards in a quality controlled environment and with UL & FM approvals, the Shield A-XT releasing panel offers outstanding value and performance for all small to medium fixed firefighting installations. With three detection zones as standard, extinguishant release can be configured to activate from any combination of detection zone inputs to allow ( among other combinations) any two from three type activations such as would be required for detection in ceiling void, room and floor void applications. The extensive configuration options of the Shield A-XT allow the functionality of the system to be extensively modified.
