Most frequently asked questions and technical information about EntraSYSTEM4.
General questions ES4:
What is the warranty period of ES4 products?
Entrya code keypads and the controller are covered by a five-year warranty against manufacturing defects. Normal wear and tear – such as, for example, discoloration caused by sunlight – is not covered by warranty. The warranty is in full accordance with the statutory provisions. Please contact your supplier (installer or wholesaler) for any warranty claims.
Is it possible to replace/repair only parts?
Our products are durable and repairable. A defective product must be returned in its entirety for repair. We do not ship individual parts. Note: returns can only be made through professional partners (installers or wholesalers).
What is the maximum number of users for Basic mode and Cloud mode?
If you choose Basic mode you can add up to 100 users, for Cloud mode it is up to 500 users (with Pro subscription).
What is the maximum pin length of a code?
The maximum pin length of a code is 8 digits.
If you are programming the controller for the first time, the first code added is your master code. The master code determines the length (4 – 8 digits) of all other codes.
The master code can be used both as an access code and to program additional codes and settings via the code keyboard.
How do I change or restore the factory settings of the controller?
Use the program button and hold it down for 18 seconds until after the green, the white light flashes according to the diagram above.
For more information, check the manual.
What is the difference between Basic mode and Cloud mode?
In Basic mode, you can program one controller with a connected code keyboard through that same code keyboard (or manage it through the app – with wifi). The controller does not require an internet connection. Basic mode is suitable for installations where there are only a few users and a maximum of two gates/doors. Adjusting codes is not often done, so management is optional rather than required. To manage via the app, you must be within wifi range of the controller.
In Cloud mode, you can install multiple controllers with and without a code keyboard. The controllers require an Internet connection. Cloud mode is suitable for installations where there are multiple users and multiple doors. Where there is a need for timetables, automatic switching user groups. Adjusting user rights is done regularly and easy management is an essential part of the installation.
How easy is the installation of EntraSYSTEM4?
Very simple! The 2-wire bus system requires minimal cabling.
The system runs on 12-24V AC/DC and can be connected via WiFi, LAN or LTE 4G.
Our documentation and training courses make installation feasible for any professional.
What is an ES4 controller?
De ES4-controller is het hart van elke opstelling.
Een slim stukje hardware – 100% ontwikkeld en geproduceerd in België – waarmee je kleine, eenvoudige installaties kan verwezenlijken (Basic-modus) of grotere complexere installaties (Cloud-modus).
Je kan controllers groeperen in één of meerdere installaties. Je kan mét of zónder codeklavier een toegang beheren en hebt de flexibiliteit om met éénzelfde controller elke toepassing tot 500 gebruikers veilig toegang te verlenen.
Het toestel functioneert zonder internet, maar ook via wifi, LTE-M / 4G en Ethernet (RJ45). Het kan dus ook makkelijk geïnstalleerd worden op locaties die mobiel zijn (bv. werfketens, evenementen).
Is the ES4 compatible with other Entrya products?
The EntraSYSYTEM4 product line is not compatible with other Entrya products.
How many doors can I manage maximum with Basic mode and Cloud mode?
If you choose Basic mode you can manage 2 doors per controller, for Cloud mode it is a total of 40 doors (with Pro subscription).
When is the ES4 controller ready to use?
- Connect the code keyboard to the ES4 controller. Connect the gray and white wires to the BUS connector on the controller. The polarity is not important.
- Connect a power supply to PWR connector of the controller. The polarity is not important.

- 7 days before the end of the subscription
- on the subscription expiry date.
After the subscription expires, a 14-day grace period starts automatically, during which all functionality remains available.
You can renew a subscription at any time. You do not have to wait for the reminder email.
Can the free Pro trial be used for multiple sites?
No. The free Pro trial can only be activated once for one site. It is not possible to transfer the trial to another site later.
How does the free Pro trial work?
When you start using ES4 Cloud for the first time and create an account, you can try the features of the Pro subscription free of charge for 30 days. This is an easy way to discover all the possibilities of ES4 Cloud.
The Pro trial can be activated once for one site. You can activate it when creating the site or later, when the Free plan no longer meets your needs.
At the end of the trial, you choose the subscription that suits you best: Free, Lite or Pro. You will automatically receive reminder emails when the trial is about to end: 7 days before the end date and again on the day the trial ends.
If you take no action, the site is automatically switched back to the free Free plan. The complete configuration is retained and no data is deleted.
Parts of the site configuration that are not available under the Free plan can no longer be used. If the site configuration does not fit within the Free plan limits, the configuration can no longer be synchronised with the devices.
You can activate a suitable subscription or adjust the site so that its configuration fits within the Free plan limits.
Can I use an ES4 controller without internet (Cloud)?
This is only possible in Basic mode. The controller is then not connected to the internet, so remote access and remote management are not available.
Access can only be granted using PIN codes via the keypad. There are two ways to manage the codes:
- Via the keypad: ideal when you only use a few codes that rarely change.
- Via the app: manage codes with your smartphone while close to the controller. This option is particularly suitable when you manage many codes or need to change codes regularly.
Can I use an ES4 controller without a subscription?
Yes. There are two ways to do this: use the free Free plan in Cloud mode or set the controller to Basic mode.
Cloud mode with Free plan:
For simple installations, the Free plan is available free of charge. It allows you to manage ES4 Cloud sites with one controller, a maximum of two doors, five users and one schedule. The number of sites you can manage with the Free plan is unlimited.
Basic mode:
The controller is not connected to the internet, so remote access and remote management are not available.
Access can only be granted using PIN codes via the keypad. There are two ways to manage the codes:
- Via the keypad: ideal when you only use a few codes that rarely change.
- Via the app: manage codes with your smartphone while close to the controller. This option is particularly suitable when you manage many codes or need to change codes regularly.
Can an installer create a site with a subscription for a customer?
Yes. The installer can transfer it to the customer afterwards.
This can be useful when the customer does not yet have an ES4 account and the installer wants to configure the system before delivery. This makes installation at the customer’s premises easier.
The selected plan (Free, Lite or Pro) is automatically transferred to the customer together with the site. With the Free plan, no further action is required. If a Lite or Pro subscription is needed, the installer can purchase it in advance. Because the subscription is linked to the site, it is automatically transferred to the customer when the site is transferred. In that case, the invoice and payment are the responsibility of the installer, who can invoice them to the customer together with the devices.
Do I need a subscription, or is the Free plan sufficient?
The free Free plan is suitable for simple ES4 Cloud installations with one controller, a maximum of two doors, five users and one schedule.
For more extensive installations, you need a Lite or Pro subscription.
Click here for an overview of the subscriptions or ask your installer for advice.
Can I purchase a subscription through the App Store or Google Play Store?
No. There are several reasons for this.
More control over subscriptions:
Because the subscription is purchased in the ES4 web portal, it is linked to the site or company rather than to an individual person’s Apple ID or Google account. This keeps the subscription easy to manage, even when an employee leaves the company.
Lower price:
For purchases made through the App Store or Google Play Store, Apple or Google charges a commission on the subscription price. To avoid this additional cost and keep our subscription prices as low as possible, subscriptions are purchased and managed directly through the ES4 web portal.
Where can I take out a subscription?
