MP Panel is missing a battery

The MP series hardware does not ship with a battery installed. These units now include a built-in internal supercap which allows the panel to store up to 10 hours of low power to maintain the clock.

If choosing to add a coin cell battery instead of the 10 hour supercap, a BR2032 or CR2032 can be installed. Configure the battery jumper as outlined in controller installation manual.

Cardholder database and event transactions have changed and those are now stored in flash memory which does not require any power so in the event of total power loss that data would be retained.

What happens when you press the reset button?

When pressing the reset button on a controller or SIO, you are sending a software reset to the board. The software reset is not a graceful shutdown, it will terminate all processes immediately. When a board does not have a reset button it is recommended to pull the terminal block or POE cable. It is not recommended to pull the jumper that distinguishes between a 12V or POE connection.

Boards that do not have a reset button:

1. LP1501

2. MR62e

Are the relays on the Mercury boards wet or dry?

The relays are dry contacts.

A dry contact output on a device like a relay means that the contacts have no voltage or potential difference across the two contacts. The contacts simply provide an open or closed state to another device.

A wet contact output on a device like a relay means that when the relay is activated, the relay output contacts supply a voltage to whatever device is connected to the relay output contacts, say for example a light or motor.

How do I convert firmware from one partner to another partner?

The firmware that Mercury provides is the same firmware for all of the Mercury OEM partners. So there is no need to flash different firmware to the boards when changing over the host software to a different OEM provider.

The only thing unique to each partner is that when the boards are ordered an OEM code is programmed into each board. Each OEM partner has the capability to program their own OEM code into the boards, but not all take advantage of this. You would need to check with the OEM partner to see if they support this ability.

The OEM codes control the look and feel of the web configuration pages as well as the OEM factory default settings. The host software also can validate that the hardware coming online with their software has been programmed with the proper OEM code.

Can I get access to the Mercury SDK / API?

The Mercury SDK / API is only available to authorized Mercury OEM partners. Access control manufacturers interested in partnership opportunities should contact sales – [email protected]

What voltage of surge protection should be used on inputs, outputs, readers, and communications circuits?

What is the minimum and maximum password length when creating users?

On the EP series controller, the minimum password length is 6 characters.  The maximum password length is 10 characters. On the LP series controllers, this has been changed to be between 8 - 64 characters.

What is the battery life of the batteries on the LP/EP series controllers?

What is the battery life of the batteries on the LP/EP series controllers?

On the LP1501 / EP1501 and LP2500 / EP2500, the stored database will be saved for a minimum of three months after power is removed, assuming that the coin cell battery is fresh.

On the LP1501 / EP1501, a fully charged battery will store the database for a minimum of three days.  It can take up to 48 hours to fully charge the re-chargeable battery.

What are overseas systems and product development limitations?

What are overseas systems and product development limitations?

Yes. Mercury readily supports product development and systems overseas. Typically, in global relationships, we work through our customer’s headquarters as an integrated adjunct to their engineering and technical support teams.

We provide all system documentation in English, so translation typically resides with our OEM partners. Located in California and operating on Pacific Time, we coordinate with our partners to overcome any time zone and working hour variances.
