WM300 Control Cable for NC300II and HC345C systems

Architects' And Engineers' Specifications

The cable shall be Alpha Communications® WM300 or approved equal and shall contain 9 conductors. All 9 conductors shall be wrapped by a GRAY .045" thick PVC jacket to form one single cable. The NOMINAL O.D. of this cable shall not exceed .590". The conductors within this cable shall be configured as follows.

One Data Assembly (1 twisted pair plus 1 cond.) #18 gauge stranded wire wrapped by an overall aluminum/mylar shield and an ORANGE .020" thick PVC jacket. This shield shall have a #18 gauge drain wire. The conductors shall be Yellow, Orange and Green, insulated by .033" thick Tapolene. The capacitance between these three conductors shall be 12.5 pF/foot. 

One Audio Assembly (1 twisted pair) #18 gauge stranded wire wrapped by an overall aluminum/mylar shield and a GRAY .020" thick PVC jacket. The shield shall have a #18 gauge drain wire. The conductors shall be Purple and Gray insulated by .016" thick HDPE.

Three #18 gauge stranded wires wrapped by an overall aluminum/mylar shield. The shield shall have a #18 gauge drain wire. The conductors shall be RED, BROWN and BLUE insulated by .015" thick PVC. 

One #16 gauge stranded wire. The conductor shall be Black insulated by .016" thick PVC.

WM300 Multiplex Nurse-Call Cable
Alpha Communications® WM300 control cable is specially made for use with the NC300/NC300II series microprocessor nurse call system. The cable features the precise combination of conductors and shielding necessary to provide optimum performance of the NC300/NC300II system.

The cable provides for simple installation, as all wire necessary for connection of the central processing equipment to master, patient, staff and duty stations is contained in a single jacket. The individually shielded and jacketed Data and Audio assemblies with drain wire ensure clear, noise-free audio communication.

Features
  • Single cable wiring (multiplexed)
