NURSE CALL
A full side communication package includes switches in both siderails for interfacing with Nurse Call, TV/Vol-
ume, and Room/Read Lights. When the switches are activated, the signalling is passed through the CPU
and into the head wall interface board which contains the 37 pin connector for the interface cable between
the bed and the wall system. The signal is a momentary switch closure and does not contain voltage. Stryker
is responsible for the successful interface between the bed and the existing system. Stryker is not responsible
for the nurse call system installation or modifications to the current system. WIthin reason, whatever your
current system or soon to be installed system does, Stryker will manufacture an interface cable that will ac-
commodate a direct hookup to the system. (Full option will interface with Nurse Call, TV, Room and/or Read
Lights).
NOTE
If the Nurse Call system is being modified to accommodate Room/Read Light controls, a step down voltage
supply should be no greater than 30 volts for the bed to interface successfully with the lights.
If pin out information is required for the bed’s 37 pin connector, see page 47.
The head wall interface board has changeable jumpers at locations J2, J3, J4, J8, HDR 12, and HDR 13.
J2 is in line with Custom Pendant Signalling
J3 is in line with Nurse Call Signalling
J4 is in line with Priority Signalling
J8 is in line with Pot Wiper for Speakers
HDR 12 is in line with Priority Signalling
HDR 13 is a storage location for jumpers
The purpose of the jumpers is to allow Stryker the opportunity to manufacture cables with fewer internal jump-
ers. The jumpers are on the board to create either a normally open or normally closed environment depending
on the system’s requirements. J2–J8 have three pins with a two pin jumper on two of the pins. A pin on the
right or left will always be open. HDR 12 and HDR 13 have four pins each and will either have all pins jumped
or none, whichever the system requires. Stryker will build the beds with the appropriate jumper locations uti-
lized for the hospital’s system. If the systems are changed in the future, it may be necessary to change jumper
locations. Call Stryker’s Technical Services for assistance. Stryker maintains records showing which sys-
tems are in use at individual accounts and how the cable should be configured. Please order replacement
cables from Stryker.
