Certis Cisco Hand Wave Sensor Singapore | Contactless Touchless Infrared Door Exit Sensor | R80 R90 Repair Replace Upgrade

The Certis Cisco Hand Wave Sensor is a contactless door-release solution designed for access-control systems where users need to activate an exit or door-opening command without physically pressing a conventional push button.

Commonly searched as R80 / R90 Hand Wave Sensor, this type of infrared touchless sensor is suitable for offices, commercial buildings, security entrances, toilets, healthcare environments, factories and other locations where convenient contactless access control is preferred.

SGCCTV provides repair, troubleshooting, replacement and upgrading of existing Certis access-control equipment and hand-wave exit sensors.

Contactless Hand Wave Door Sensor

A traditional access-control exit button requires:

PRESS BUTTON → CONTACT CLOSES → DOOR RELEASES

A touchless infrared sensor operates differently:

WAVE HAND → SENSOR DETECTS → RELAY ACTIVATES → DOOR UNLOCKS

The user does not need to physically touch the sensor surface.

This makes it particularly convenient for high-traffic entrances where many people use the same door-release device every day.

Typical System Configuration

A hand-wave sensor normally forms only one component of the complete access-control system.

A typical installation works as:

Hand Wave

↓

Infrared Sensor

↓

Relay / Exit Input

↓

Access Controller / Lock Circuit

↓

DOOR RELEASE

Touchless Access Control

Contactless exit sensors became especially popular during the COVID-19 period because organisations wanted to reduce unnecessary touching of shared surfaces.

However, the current value of a touchless sensor extends well beyond COVID-related applications.

It provides:

Convenient Hands-Free Operation

Reduced Physical Contact

Less Mechanical Button Wear

Modern Access-Control Appearance

Easy Operation

Suitable for High-Traffic Doors

It can therefore remain a useful access-control upgrade even where infection-control considerations are no longer the primary reason for installation.

Infrared Hand Detection

Touchless exit sensors typically use infrared proximity detection to recognise a hand presented within the configured sensing zone.

No physical pressure is required.

This eliminates the mechanical action associated with a traditional push-to-exit button.

Depending on the replacement sensor selected, features can include:

Adjustable Detection Distance

LED Status Indicator

Relay Output

NO / NC / COM Contacts

Adjustable Relay Time

12VDC Operation

Exact specifications should be confirmed from the installed R80/R90 unit or proposed replacement model before installation.

Important R80 / R90 Model Identification

For older Certis installations, R80 / R90 identification should be confirmed from the physical unit, rear label, controller documentation or wiring before replacement.

The model designation alone is not sufficient to assume electrical compatibility.

Before replacing an old hand-wave sensor, check:

Operating Voltage

Relay Type

NO / NC Requirement

Existing Wiring

Mounting Size

Back Box

Access Controller Input

Lock Configuration

This avoids replacing a failed sensor with a device that physically fits but is electrically incompatible.

Certis Access Control Repair

If an existing Certis hand-wave sensor stops working, the sensor itself may not necessarily be faulty.

The complete circuit should be checked:

SENSOR → WIRING → CONTROLLER → POWER SUPPLY → LOCK

Possible faults include:

No Power to Sensor

Infrared Sensor Failure

Relay Failure

Broken Cable

Loose Terminal

Access Controller Fault

Power Supply Failure

Weak Backup Battery

EM Lock Failure

Door Release Timing Problem

Incorrect NO/NC Connection

Replacing the sensor without diagnosing the circuit can therefore fail to solve the actual problem.

Hand Wave Sensor Not Detecting

A common symptom is:

Wave Hand → No Response

The technician should check whether:

1. The sensor has DC power.
2. Its status LED is operating.
3. The infrared detector responds to a hand.
4. The internal relay changes state.
5. The relay output reaches the access controller.
6. The controller receives the exit command.
7. The electromagnetic lock releases correctly.

This isolates whether the fault belongs to the sensor, wiring, controller, PSU or lock.

Sensor Detects Hand but Door Does Not Open

Another common problem is:

Sensor LED Changes → Door Remains Locked

This often indicates that the infrared detection stage is functioning.

The problem may instead be related to:

Relay Contact

Exit Input Wiring

Access Controller

Door Release Programming

Power Supply

EM Lock

Electric Strike

The correct troubleshooting process is therefore important before purchasing replacement equipment.

Door Opens by Itself

An ageing or incorrectly configured touchless sensor can also cause unwanted activation.

Possible causes include:

Detection Range Too Long

Reflective Objects

Movement Close to Sensor

Electrical Noise

Loose Wiring

Damaged Sensor

Sticking Relay

Incorrect Installation Position

An automatically opening access-controlled door can create a security problem, so intermittent false triggering should be investigated promptly.

Repair or Replace?

Older access-control sensors may sometimes be repairable, but replacement is usually preferable where the sensing electronics or relay have become unreliable.

A practical decision is:

Repair

Suitable when the problem is caused by:

Loose Wiring • Connector • Power Supply • Configuration • Controller Input

Replace

Suitable when there is:

Failed IR Sensor • Failed Relay • Damaged PCB • Physical Damage • Obsolete Sensor

Upgrade

Suitable when the existing model is discontinued and a modern contactless exit sensor can be integrated with the existing access-control system.

Replacing an Obsolete R80 / R90 Sensor

An obsolete sensor does not necessarily mean the entire access-control system needs replacement.

If the existing controller accepts a conventional dry-contact exit input, a compatible modern hand-wave sensor may potentially replace the older unit.

The replacement process should confirm:

OLD SENSOR → VOLTAGE → RELAY LOGIC → WIRING → CONTROLLER → NEW SENSOR

This can be substantially more economical than unnecessarily replacing the reader, controller, power supply and electromagnetic lock.

Existing Certis System Upgrade

Older Certis access-control installations may still have serviceable:

EM Locks

Door Contacts

Card Readers

Controllers

Power Supplies

Cabling

When upgrading, SGCCTV can first determine which components remain usable.

The objective is to replace only equipment that is faulty, obsolete or incompatible rather than automatically replacing the complete door system.

Suitable Applications

Contactless hand-wave exit sensors are suitable for commercial offices, factories, warehouses, server rooms, retail shops, clinics, laboratories, schools, toilets, clean environments, security rooms, condominiums and other access-controlled premises.

They can also be useful where users frequently carry boxes, tools or equipment and a conventional push button is inconvenient.

Hygiene & Contact Reduction

Touchless operation can reduce routine physical contact with a shared exit button.

However, marketing should avoid claims such as:

“Stops viruses” or “prevents COVID.”

A hand-wave sensor does not sterilise an environment or guarantee prevention of viral transmission.

More accurate wording is:

“Contactless access-control technology designed to reduce unnecessary touching of shared door-release surfaces.”

This keeps the hygiene benefit technically credible without making unsupported medical claims.

Access Control Power Supply & Battery

When troubleshooting an old hand-wave sensor, technicians should also inspect the access-control power supply.

A weak PSU or ageing backup battery can cause:

Intermittent Door Release

Sensor Restarting

Controller Rebooting

EM Lock Chattering

Unstable Relay Operation

Door Failing to Unlock

The sensor should therefore be tested as part of the complete door-access system rather than in isolation.

10 Frequently Asked Questions

1. What is a Certis Cisco hand-wave sensor?
It is a contactless exit device used with an access-control system. Instead of pressing a physical exit button, the user presents a hand near the sensor to initiate the door-release command.

2. Does a hand-wave sensor require physical contact?
No. A properly operating infrared touchless sensor detects the user’s hand without requiring the sensor face to be pressed.

3. Can SGCCTV replace an old R80 or R90 sensor?
Yes, subject to inspection of the existing model, voltage, relay configuration, wiring and access controller.

4. Must the entire Certis access-control system be replaced?
Not necessarily. If the controller, lock, PSU and cabling remain serviceable, it may be possible to replace only the faulty or obsolete sensor.

5. Why does the sensor detect my hand but the door remain locked?
The problem may be downstream of the sensor, including the relay wiring, controller exit input, power supply or electromagnetic lock.

6. Why does my touchless sensor sometimes activate by itself?
Possible causes include excessive sensing distance, nearby movement, reflections, electrical problems, incorrect positioning or a failing sensor/relay.

7. Can a modern hand-wave sensor replace an obsolete model?
Potentially. Compatibility depends on operating voltage, relay contacts, controller input requirements, mounting and wiring.

8. Is a hand-wave sensor more hygienic than a push button?
It can reduce the need to touch a shared door-release surface. It should not, however, be marketed as preventing COVID-19 or stopping viruses.

9. Can SGCCTV troubleshoot the existing access-control system before replacing parts?
Yes. The sensor, wiring, controller, PSU, battery and lock circuit can be checked to identify the actual source of the fault.

10. Can the system be upgraded without changing the existing door and EM lock?
Often yes, provided the existing equipment remains electrically compatible and in serviceable condition.
