Door Security

A fail-safe lock unlocks when power is removed, and a fail-secure lock stays locked. The STP STP-EB133 is fail safe, allowing egress in a power failure, which suits escape routes. The STP STP-SB260 is fail secure, so the bolt remains locked if power is cut, and it has a key override. The Abloy EL580-50MM is listed with both fail-locked and fail-unlocked operation.

A drop bolt is an electrically operated bolt for locking swing doors, including glass doors. The Abloy FF843 fits horizontally or vertically, can be fitted to glass doors and unlocks automatically for 9 seconds; the RGL DBGLS150 is a fail-safe glass door drop bolt with a relock timer of 3, 6 or 9 seconds; and the STP STP-EB170 suits single or double action doors.

Yes, many bolts here include door position monitoring. The STP STP-EB133 has a door status contact that shows whether the door is open or closed, the STP STP-EB150 and STP-EB180 monitor door position with a variable relock delay, and the Abloy FF843 has integrated door and locking monitoring contacts.

Yes, with a retrofit adapter. The EZVIZ DL01S fits on the inside of most standard deadbolts with no drilling and unlocks by app or local Bluetooth. Remote access and notifications need the EZVIZ A3 Home Gateway on Zigbee, and the kit version adds the DL01CP outdoor keypad, rated IP56, with passcode and proximity-card entry and a doorbell.

By battery, by a wired supply, or a mix of the two, depending on the model. The Ajax DoorBell 66392.125.GP1 is wired at 12–24 V DC or 16–24 V AC; the EZVIZ HP3 Pro has an internal battery, a solar panel and USB-C charging with optional 8–24 V AC wiring; and the Pyronix DoorbellCam2 charges by USB-C or can be hard-wired to 12–24VAC.

Not always, because several doorbells here store clips locally. The EZVIZ EP3x Pro and HP3 Pro have 32 GB of built-in eMMC storage, so basic recording needs no subscription, and the Pyronix DoorbellCam2 records to a microSD card without a subscription. Optional cloud storage is listed for the EZVIZ EP3x Pro and the Pyronix DoorbellCam2.

Choose wired on an Ajax Fibra system and wireless where cables are impractical. The Ajax DoorProtect Fibra 44393.03.WH1 connects over the Fibra wired bus, and the DoorProtect Plus Fibra adds shock and tilt sensing. The wireless DoorProtect U 121293.03.WH1 uses Jeweller radio with a pre-installed CR123A battery that lasts up to 7 years in typical use.

It is the mounting panel for Ajax DoorProtect detectors. The SmartBracket, such as the 9520.03.BL, lets you fix the detector without opening its case, keeps its tamper function working through a perforated section and makes battery changes easier. The 22051.03.BL and 22053.03.WH versions hold the magnet half of DoorProtect and DoorProtect Plus contacts.

A hub, detectors and sirens ready to install together. The Ajax KIT2 S 90765.243.WH1 includes a Hub 2, two MotionProtect S detectors, a DoorProtect S door sensor, two SpaceControl keyfobs, a StreetSiren and a HomeSiren S, and the KIT5 S 90771.246.WH1 swaps the keyfobs for a KeyPad Plus S. EZVIZ also offers a 4-piece home sensor kit.
