Frequently Asked Questions
What are the Battery Life expectations of ENGAGE devices?
• Schlage Control: Battery life is 1.5 - 2 years depending on use.
• Schlage NDE: Battery life is 1 - 2 years depending on use.
• Schlage LE: Battery life is 1 - 2 years depending on use.
NOTES
•
•
Advanced device reader sensitivity settings (High/Max) and Mobile Enabled device
settings (Performance, Communication Range) will reduce battery life
What happens when a device battery gets low?
• All battery enabled devices provide local feedback to the user at the door when the batteries are
low. Nuisance Delay
• Low Battery status causes the lock to provide a “Nuisance Delay” LED display before allowing
normal access.
• Nuisance Delay is about 3 seconds with flashing RED LED followed by the normal Access Granted
Green LED.
• A Nuisance delay flashing RED LED followed by a GREEN LED, with access granted is NORMAL
OPERATION. – Batteries need replaced
• A Nuisance Delay will be seen for up to 500 operations to allow time for the user to inform the
Administrator that maintenance is needed.
• When the Nuisance delay is ignored, devices will enter “Critical Battery” mode and stop operating.
• Devices in critical battery mode do not operate normally or allow access
• A Pass-Through credential may be able to gain access to the device
• Mechanical key access may be required
• Control devices may use its Jump Start feature.
• Schlage NDE and LE devices display a RED LED ON solid (under the battery cover) when the lock
has entered “Critical Battery” mode.
• The batteries must be replaced to begin normal operation.
What is a Nuisance Delay?
• Nuisance Delay operation is normal device operation when a device has entered its low battery
mode. Normal access will be delay for a few seconds with the RED LED flashing, followed by
unlocking and the GREEN LED while in Nuisance mode.
• A Nuisance delay occurs any time a valid credential is presented to a device with Low Batteries.
• Nuisance Delayed access is intended to allow the user time to tell the Administrator that the
device needs attention.
• Access will be provided for up to 500 operations during Low Battery, Nuisance Delay operation.
• When a Nuisance Delay is ignored long enough that the device cannot reliability operate, the
device transitions into “Critical” battery mode and stops normal operation.
