Edwards (EST) fire alarm systems protect large and complex sites, from campuses to high-rise buildings. We stock genuine Edwards parts for EST4 and EST3 life safety panels, Signature series intelligent detectors and modules, and Edwards notification devices, so engineers can maintain, extend and upgrade Edwards systems.
Edwards products we stock
- EST4 panel modules – the 4-CPU-E CPU module, graphic annunciator CPU, touchscreen and LCD displays, 24V zone control cards, audio, telephone and microphone modules, power supply modules and USB hubs.
- EST4 networking – SFP network controllers such as the 4-NET-TP twisted-pair controller, single-mode and multi-mode fibre controllers, Ethernet network cards and network firewall adapters.
- EST3 parts – Series 3 cabinets and chassis, the 3-SDC1-E Signature driver card, single and dual loop controllers, zone annunciators and battery temperature sensors.
- Signature series detectors – intelligent SIGA-OSDI optical smoke detectors, photo/heat and optical/heat multisensors, fixed and rate-of-rise heat detectors, and standard, isolator, relay and sounder bases.
- Signature modules – single and dual input, riser, monitor, control relay, input/output and universal Class A/B modules, many with built-in isolators (SIGI).
- Notification devices – compact wall sounder-beacons, sounders and beacons in red or white, strobe expanders and a ceiling speaker strobe.
- Accessories – annunciator mounts, frames and doors, cables, brackets, hinges, locks, ferrite kits, call points and frontplates, and 12V sealed lead acid batteries up to 50Ah.
Buying Edwards parts
- Quote the part number – Edwards parts are ordered by code (for example 4-NET-TP or SIGA-OSDI); check the label on the existing module.
- European versions – codes ending in -E are European (EN 54) versions; match these to UK and European systems.
- Isolator or standard – SIGI devices include a built-in isolator, and isolator bases are also available; follow the loop design.
- Network media – choose copper or fibre SFP controllers to suit the cabling between EST4 panels.

Edwards FAQs
What is Edwards EST4?
EST4 is Edwards' modular life safety platform for fire detection and emergency communication, built from CPU, display, loop, audio and network modules.
What does SIGA and SIGI mean?
Both are Signature series intelligent devices. SIGI versions include a built-in short-circuit isolator.
Do you supply EST3 spares?
Yes. We stock Series 3 cabinets, chassis, loop controllers, driver cards and zone annunciators for existing EST3 systems.
