ASSIST Notification System

ASSIST is a compact, hard-wired alert and signalling system designed for smaller facilities that don’t require a full nurse-call platform. It allows users to raise Red (High), Yellow (Medium), or Green (Low) priority notifications via buttons, with visual and audible alerts shown on Indicators.

The system consists of four components:

• • ASSIST Button – Used to raise/cancel alerts; includes priority colour selection.
  • ASSIST Local Indicator – Lights above doors or in corridors to show alert location.
  • ASSIST System Indicator – Central audible/visual annunciator.
  • ASSIST System Controller – Powers and manages the whole system.

At minimum, you need 1 Button + Local Indicator + 1 Controller.

Green (Low): Slow repeating single chime
Yellow (Medium): Moderate double-chime
Red (High): Rapid single-chime

ASSIST is intended for small clinics, therapy rooms, allied health suites, bathrooms/toilets, consultation rooms, schools, shops, superstores, restaurants, supermarkets or any environment requiring simple and reliable signalling without complex network infrastructure.

You can buy the ASSIST system from Miracle Electronics through one of its resellers with future opportunities to purchase from a local wholesaler.

Press the large centre button. It lights up in the selected priority colour and triggers connected Local Indicators and any System Indicators.

Press the small cancel/reset button. A triple-tone will confirm cancellation, and all indicators will turn off.

Triple-press the cancel button. The button will:

• • Flash brightly
  • Disable its main activation for ~10 seconds
  • Play countdown tones when exiting cleaning mode

A Local Indicator stays on until the corresponding Button is cancelled. It always reflects only the colour of its paired Button, even if other buttons have higher-priority alerts.

Approximately 80dB at 1 foot at maximum volume, adjustable using the rear pot.

System Indicators show only the highest priority active alert in the system. Local Indicators only shows the alert of the button it is connected to.

4-core, 0.44mm² cable (or equivalent) for bus cabling. Total bus length should not exceed 100 metres. Local Indicators and auxiliary inputs are wired directly to Buttons, not to the bus.

Up to 20 Buttons (each button with a Local Indicator connected). For 20 devices, split number of devices to 10 per bus port. System Indicators also count toward device limits.

Each button must have a unique address (0–19), set using:

• • Rotary dial (0–9)
  • High/Low switch (adds +10)
  • Duplicate addresses trigger flashing + beeping.

A three-position switch selects:

• • Green (Low)
  • Yellow (Medium)
  • Red (High)

  This determines the colour displayed and the tone played.

For help/warning purposes, typically 1200–1500 mm above finished floor level.

Place in visible, frequently staffed locations (reception, staff rooms, offices). Multiple indicators can be used to increase coverage.

The documentation notes a UPS may be used if backup is required.

All devices operate on 12VDC nominal (8–14V). Source is provided by the Controller.

Button: 15mA idle, 35mA average active, 90mA peak w/ Indicator
Local Indicator: 20mA active
System Indicator: 20mA idle, 120mA peak
Controller: 15mA idle, 12VDC 2A output per channel

Buttons include a dry-contact auxiliary input that can trigger or reset notifications from compatible devices (e.g., pull cords, external switches). They are Normally Open by default.

Check:

• Cabling/terminations
• Short circuits
• Whether the Controller port is overloaded

It has a duplicate address. Change to a unique address.

Possible causes:

• • Incorrect wiring
  • Short circuit
  • Incorrect colour wiring at the indicator

Wiring and terminations. Check for a short circuit and ensure button has a unique address.

A button was likely disconnected while active. Power-cycle the Controller (off for ~10 seconds).

There is a short between bus and power (12V/GND). Check wiring at all bus devices.

The Bus port is overloaded or there is a short circuit.

The installer manual lists the following compatible devices:

• • CareCall Socket Plate
  • CareCall Pull Cords (Green/Red)
  • Wet-Environment Button
  • Clipsal gasket
