How much area of wall space is needed in the telecommunications room (TR) to support a nurse call system?

1.2 m x 1.2 m (4 ft x 4 ft) is too small to house a nurse call headend system; it does not provide sufficient space for the control unit, power, and termination hardware.

Per BICSI TDMM healthcare infrastructure guidelines, the nurse call headend equipment requires a minimum wall-mounted footprint of 1.2 m x 2.4 m (4 ft x 8 ft) in the TR. This dimension accommodates the main control unit, power supplies, and associated termination hardware while providing adequate clearance for maintenance access and cable management as defined in healthcare facility design standards.

2.4 m x 2.4 m (8 ft x 8 ft) significantly exceeds the required wall space for a nurse call headend and is not the dimension specified by BICSI TDMM healthcare guidelines.

2.4 m x 3.6 m (8 ft x 12 ft) is more than double the required space and does not correspond to any nurse call headend wall space specification in the relevant standards.
