Ideal for use in apartment blocks or in buildings containing multiple businesses.
Each system will need a control unit, (analogue, IP or anti-vandal options) which is supplied as one module, with 0, 1 or 2 buttons. This can then be extended by adding modules as required, whether additional buttons, a keypad, a door access card reader, a loudspeaker or camera.
Accessories provide more even flexibility, adding locks, power supplies, exit switches and emergency break glass modules to the system.
The modules are contained in either a surface or flush mounted box, which can be protected by a weather hood for external applications.
