Grey Shield Security Services Ltd
We work closely with manufacturers and industry training authorities to provide the best service possible. This can range from a small non addressable system in a clinic to a multi loop addressable system within a multi story office complex following the strict regulations set out by the British Standards (BS5839-1:2017).
Non-addressable systems are commonly referred to as conventional systems due to the available technology at the time. Nonetheless, addressable systems are becoming more common as technology advances, therefore changing the state of what a conventional fire alarm is and for this reason we do not refer to non-addressable systems as conventional systems.
Non-Addressable: Commonly used in smaller premises as they consist of a control panel with detectors connected via a radial circuit. Most non-addressable systems on the market have a very basic control panel consisting of primary command keys and LED notifications however, non-addressable systems installed by us have a LCD display, user functions, access key and other features that help it stand above the rest in a competitive market.
Addressable: Fast becoming the standard system due to the advances in technology and the prices of systems becoming more affordable. Addressable systems consist of a control panel with devices wired in a loop circuit. Therefore, all devices have their own address meaning you are notified if there is a fault or activation on any device within the system. Consequently reducing the time spent fault looking for the activation or the need to call out an engineer.
Wireless/Hybrid: With the ever changing technology available on the market today, wireless alarms have become a system that can be trusted. Ultimately a hard wired system is still superior however some scenarios just cannot accommodate the cables whether this is due to the property being a graded building or other issues such as health and safety where asbestos may be involved. These systems consist of a main control panel with wireless “expanders” connected either by hard wire or radio link which then communicate with the wireless devices to transmit signals to the main control panel in the event of a fault or fire.
