Audio-tactile help call system — complex (stand + sign + button + receiver)

Audio-tactile help call system — complex

Independent help call for the disabled (wheelchair users, the elderly, the blind/deaf) — calling a staff member with one button press, confirmation by an audio message.

A complex of 4 components:

1. A yellow metal stand — a structure installed on a wall or floor (1500×400×200 mm, steel, the base coated with black powder paint).
2. A yellow audio sign for the disabled — a yellow background + an audio bell symbol + a wheelchair + Braille (200×200 or 300×300 mm).
3. A help call button — a white plastic housing, a red press button (80×80×30 mm, press force < 5 N — light for the disabled/elderly). Connection: wired 24V DC or wireless (433 MHz / Wi-Fi).
4. A receiver — a red/black compact device (in the staff room). A voice message («Help needed in room N»), an LED indicator, a history log (the last 100 calls).

3 help functions (Universal Design):

• Visual: yellow background, red button, LED indicator
• Tactile: Braille, a physical press button
• Audio: a voice message, a bell sound (with an induction loop also for the deaf/hard of hearing — IEC 60118-4).

Use scenarios:

• An accessible government institution entrance — a wheelchair user calls a staff member
• An accessible hotel room — a patient requests help
• An accessibility zone in a shopping centre — service is required
• An accessibility department in a university/lyceum — a student requests help
• A hospital reception — a call from where the patient is lying

SP 59 mandatory requirement: Section 5.5.3 (audio-visual alerting for the disabled), Section 8.1.7 (help-call means for the disabled) — checked in large government institutions.

Technical specifications: 12V/24V DC, 5-15W, operating temperature -10°C…+40°C, audio power 65-85 dB (adjustable), wired range 30 m, wireless 30-100 m, service life 50,000 hours (10+ years).

Set: this system + QM-EVAK-LED-SCROLL-RED-001 (LED running text — «Help request» text) + QM-EVAK-INFO-POINT-001 (green information point) = a complete package.

Standards: compliant with the requirements of GOST R 51261-2017, IEC 60118-4 (induction loop), SP 59.13330.2020 (Section 5.5.3, 8.1.7), GOST R 53453-2009.
