Fail-safe electric deadlock for concealed security. The door unlocks when power is lost. Dual voltage: 12/24 VDC. SECO-LARM electric deadbolts provide concealed deadbolt security for most wooden or hollow metal doors and offer the added convenience of electrical operation. They are designed for hollow metal door frames and are not recommended for wooden ones, although the door itself can be made of either material.
