Install An Electric Lock In A Metal Door Jamb<

Designed for hollow metal door frames, the Seco-Larm Enforcer Electric Deadbolt (Fail-Secure, 12/24 VDC) adds electric deadbolt control to a wooden or hollow metal door. Because the deadbolt features fail-secure operation (locks if power is lost), it also incorporates a manual lock/unlock cylinder that works with the included turnkeys (turn lock knob from inside protected premises and/or use key from outside protected premises). The deadbolt works with Seco-Larm keypads and features shallow design for installation in most metal door jambs.

  • Fail-secure operation (locks if power is lost)
  • Manual lock/unlock cylinder allows operation in power outage
  • Stainless steel for strength and long life
  • Adjustable door lock delay timer (0, 3, 5, or 9 seconds)
  • Magnetic switch determines door position for positive locking

The Electric Deadbolt is powered by a solenoid. If the door is not closed properly, the solenoid will attempt to lock, but then shuts off to avoid burning out. Once the door is closed properly, it will automatically lock.

  • Stainless steel bolt, 5/8" diameter, 5/8" throw
  • Includes control wire which allows for releasing without cutting unit's power
  • Over-current protection 1.5A
