## Description

The Seco-Larm Enforcer Mini No-Cut Electric Door Strike (Fail-Secure) is used to convert a cylindrical lockset into an electronic access-controlled locking system. This "no-cut" model is specially designed to fit most metal or wooden doors with only minimal cutting required of the door frame beyond the hole for the strike. Installation is further simplified by the strike's 2-wire, non-polarized connection to your access control or egress device, as well as its reversible non-handed design to fit either right- or left-handed doors.Fail-secure operation (door remains locked if power is lost)Works with any cylindrical door locking systemProvides 1,000-pound holding force/static strengthNon-handed for use with left- or right-handed doorsUses 2-wire, non-polarized connection to access control or egress deviceStainless steel keeper for strength and long lifePowered by a solenoid, not a buzzer coil (12VDC)The door strike includes both a stainless steel no-cut strike plate and a silver-colored aluminum low-cut strike plate to accommodate almost any cylindrical door locking system. (An alternative bronze-colored aluminum low-cut strike plate is optionally available, sold separately – SD-991RA-61Q/B). All required installation hardware is included.The strike connects to digital keypads, pushbutton switches, and other entry devices, and it features shallow design to support use with most metal doors. It offers fail-secure operation, so when power is lost, the strike locks the door.ContentsElectric Door StrikeStainless Steel No-Cut Strike Plate (SD-991SS-61Q/S)Silver Low-Cut Strike Plate (SD-991RA-61Q/A)(2) Mounting Screws(2) Splice Connectors(2) Strike Plate ScrewsMounting TemplateInstallation ManualNOTE: For indoor use only.Technical DetailsManufacturer Part #: SD-991A-D1QUPC: 676544018230Operating Voltage: 12VDCCurrent Draw: 280mA at 12VDCHolding Force: 1,000 pounds (454kg)Endurance: 250,000 Cycles (Factory tested)Latch Throw: 1/2" (13mm)Operating Humidity: 0 to 85 percent (non-condensing)Operating Temperature: 14° to 120°F (-10° to 49°C)Approvals: CE, RoHSWarranty: 1 Year

Review: Secure and unobtrusive with a great design - This is a high-quality, compact steel electric strike that offers excellent function and security without taking up much space. Once installed, it is unobtrusive and has a great design. However, the seller's listing lacks specifications regarding its dimensions, which is essential to review prior to purchase.
Review: The smallest strike I could find - I was looking for the smallest strike that would require the least amount of modification to my door frame. I'm pretty sure this is the one. Like many others, it does have issues releasing if there is any pressure on the latch, or if there is any torque on the mounting plate, but when it's installed *correctly* it gets the job done nicely, and more importantly, discreetly. I'll be picking up two more to finish the project I started.

## Questions & Answers

**Q: could i use this strike plate to replace my trine 014c strike plate ??**
A: We asked the manufacturer and they replied: "Yes that should work."

**Q: Is there a "fail safe" variant of this strike?**
A: Fail-safe and fail-secure are specific to the lock mechanism, NOT the access panel. Some strikes are convertible to either. This one is listed as "fail-secure" (locked with no power applied) only.

**Q: Can this be used with a standard home depot wood door?**
A: This lock is very compact. I used this lock in an ordinary residential door casing. It did not fit directly into the pre cut hole but with very little work the hole can be enlarged to accommodate this lock. I would recommend the lock not only for function but price as well.

**Q: What kind of controller can I use if I want Alexa to control it?**
A: You would need a 12VDC power supply and a relay that Alexa can control.  Maybe something similar to this: https://www.amazon.com/dp/B085HP2GJX

### ⭐⭐⭐⭐ Seems to be working good.
*by C***. on October 3, 2024*

So far they are working excelling. My only complaint is the location where the wire comes out. It should come out at the "back" of the lock rather than the end. Makes it difficult to avoid screwing through the wire. Have not had to replace one yet, but concerned it may be difficult to replace should a failure happen because of the wire location.
