The eForce-150 from Adams Rite, a unit of Assa Abloy, is a new battery-operated keyless entry control for the supplier's deadbolts, deadlatches and exit devices that are compatible with aluminum stile, steel and wood door applications. The device can accommodate up to 150 users (including master, supervisor and emergency users), plus two one-time codes. The unit can operate in three modes: Standard, Passage and Lockout. All programming is accomplished via the keypad. Device operation is confirmed by both a visual LED light indicator and an audible sound generated by a piezo horn.
