The all-new Alfred DB2S smart lock now comes with a built-in RFID card reader and can hold up to 250 unique cards (includes 2 RFID Tags in box), 250 Pin code storage and Auto re-locking with an adjustable timer. Also, now with a rechargeable lithium-ion battery pack, no longer need to be fumbling with alkaline batteries. Along with these new features it continues to maintain a streamlined lock design with 2 Finish Options (Black Chrome or Satin Nickel) and illuminated touch screen. It utilizes Bluetooth connectivity with our Alfred Home App (iOS and Android) to control and monitor your smart lock and user settings locally from your mobile device. If you have the need to monitor your locks activity while you’re away from home, the DB2S is compatible with the Alfred Connect WIFI bridge (sold separately) to give you peace of mind while away or give you the option to lock and unlock your door remotely. The DB2S continues to be DIYer friendly and includes a fully digital install process powered by BILT to make installing a breeze. The DB2S allows you to also create unlimited digital Bluetooth keys that can be shared with friends, family or even renters, within the Alfred Home App making it a great partner for any busy household or even a rental property. The DB2S Series locks are also compatible with Z-Wave 800 LR and Zigbee 3.0 systems, with the addition of an add on Module (sold separately) allowing you to add your Alfred Smart lock into your existing third party smart hub system like SmartThings, Vera or Ring Alarm.
