Home Nurse Call System - Signaling Device

The Home Nurse Call System uses a microprocessor to monitor the open loop momentary push button (Call Button), the reset/cancel button, the supply voltage and provides control for sounder, LED and relay outputs. The Nurse Call System is set to alarm the instant the Call button is depressed. The sounder will continue to sound until the reset/cancel button is depressed. Other features for the NC-20 would include an adjustable sounder volume, power/alarm LED indicator, low battery indicator and (2 form C relay) contacts for control of external devices.

The NC-20 Series is designed as a signaling device for use as a self contained Home Nurse Call System. The Model NC-20 will sound a local alarm and flash an LED indicator, should anyone press the supplied (CB-20) Call Button. The GRI NC-20 is also equipped with a form C relay output connections for use with external signaling devices.

The NC-20 and NC-21 have two form C relay contacts that will close or open on alarm for signal output. On the NC-20, once the alarm sounds, you will have a 60 second delay before tripping the relays so the caregiver has time to reset the alarm before the other device such as security control, phone dialer or remote sounder is triggered. On the NC-21 the alarm sounds and the relays trip, so the caregiver can respond as soon as the button is pushed. This allows for other devices to be tripped, such as remote sounder, light or control panel in another location to inform the caregiver of the patient’s needs. This gives you two options; 60 second delay with the NC-20 and instant on with the NC-21 to interface with up to two other devices at the same time as needed.
