The Network communication card (allows up to fourteen ECU-8 or ECU-8NT or ECU-4 or ECU-16 to be interlinked – one required per networked ECU-8 or ECU-8NT or ECU-4 or ECU-16). Use for EVC control units whi is part of the Fire Telephone & Disabled Refuge Systems range from Context Plus, supplied and supported by SPS. • The ECU722 is a network card that is used for expanding the fire telephone or disabled refuge systems of Context Plus. • Allows up to 14 ECU-4, ECU-8, ECU-16 or ECU-8NT SigTEL master controllers to be interlinked. • One card required per networked SigTEL master controller. • Allows systems of up to 224 lines (14 x ECU-16 controllers) to be easily set-up. • Any ECU-4, ECU-8 or ECU-16 can take control of the system at any time by the input of a special code. • Note that for networked systems that do not require multiple control points, controllers without handsets are available (ECU-8NT). • To network a controller that has an optional ECU-224 desk controller fitted use an ECU723 interface/network card instead of an ECU722.
