The basics

Four parts. One working door.

An access control system decides who can open a door, and when. Every door needs the same four parts, plus a bracket when the door shape needs one.

Choose the lock

Which lock suits your door?

Start with the door, not the reader. The door decides the lock and the bracket.

Door opening direction plan view Which way does your door open? Floor plan view. Stand on the inside, where the lock will be fitted. You push it: opens away EM lock fits on the frame, no bracket OUTSIDE INSIDE · lock side You pull it: opens towards you Use the Z + L bracket set OUTSIDE INSIDE · lock side
Your door Best lock Bracket Good to know
Wooden or metal door in a frame, opens away from the lock side EM lock 600 lbs None in most cases. L bracket if the frame is too narrow The most common office and cabin door
Wooden or metal door, opens towards the lock side EM lock 600 lbs Z bracket + L bracket The Z + L set lets the magnet sit on the door top
Wooden door where you want a hidden bolt Drop bolt (DBWD-02) None The bolt drops into a hole in the frame; the door must close accurately
Door with an existing mortise lock and handle Electric strike (STFC-02) None Keeps your handle and key; replaces the strike plate in the frame
Glass door with an aluminium frame EM lock 600 lbs As for wooden doors (by opening side) The plate fixes on the aluminium top rail
Frameless glass door, wall or frame above EM lock 600 lbs, or a frameless glass door lock (DBFG-05) U bracket for the EM lock The U bracket clamps the plate to the glass, no drilling
Frameless glass door with a fixed glass panel beside or above EM lock 600 lbs GG bracket For glass-to-glass fitting where there is no frame at all
Double door (two leaves), opens away from the lock side EM lock 1200 lbs double leaf None in most cases One body with two magnets, one for each leaf
Heavy main entrance door EM lock 1200 lbs single leaf By opening side For heavy or high-traffic doors
Rolling shutter, sliding door or metal gate These need a different lock. See electronic locks for main gates or send us a photo.

Not sure which way your door opens? Stand on the inside, where the lock will be fitted. If you push the door to open it, it opens away from the lock side. If you pull it, it opens towards the lock side.

EM lock, drop bolt or electric strike?

Brackets

The bracket makes the lock fit.

An EM lock has two halves: the magnet on the frame and the steel plate on the door. A bracket is needed when the door does not give those two halves a flat place to meet.

Readers

Choose how people get in.

Pick by who uses the door and where the reader will be mounted.

Entry method Best for Indoor models Outdoor / weatherproof models
Card + PIN Offices, staff rooms, server rooms. Lost cards can be removed WP-25, SA32, RFMT-22 WPRF-1K, Waterproof standalone controller
Fingerprint + card + PIN No shared cards; stricter rooms F200, FP-45, AC-X7, BioMax N-Access 10 eSSL JS-36E (IP65), IP68 fingerprint panel

Cards must match the reader. Readers use either 125 kHz (EM) or 13.56 MHz (Mifare/IC) cards, and the two are not interchangeable. Check the reader's product page before buying extra cards. Our 125 kHz vs Mifare guide explains the difference.

Exit and safety

The way out matters too.

An access-controlled door must always let people out without a card. That is the job of the exit switch.

All exit devices: exit switches and emergency release.

Power

Power that keeps the door working.

Most access control locks and readers run on 12 V DC. Use a proper access control power supply, not a phone-style adapter.

Size it correctly

Add up what the lock and reader draw, then choose a supply rated higher. For example, our 600 lbs EM locks draw about 420 to 500 mA at 12 V. A 12 V 3 A access control supply has plenty of room for one lock and one reader.

The supply we fit

The PK-80 (K80) access control power supply gives 12 V 3 A and has an adjustable door-open delay of 0 to 15 seconds.

Need battery backup or a bigger supply? Read choosing a power supply for access control.

Installation

How a door is wired.

An overview so you know what your electrician will do. Always follow the wiring diagram supplied with your reader and lock.

  1. Mount the lock and bracket. Fix the magnet on the frame and the plate on the door so they meet flat when the door closes.
  2. Fix the reader and exit switch. The reader goes outside next to the door, the exit switch inside at hand height.
  3. Place the power supply. Mount it inside, near a 230 V socket, away from water.
  4. Run the cables. Use multi-core cable from the power supply to the lock, reader and exit switch.
  5. Connect the lock to the relay. A fail-safe lock (like an EM lock) is normally wired so power is removed to open. A fail-secure lock is wired the other way. The diagram for your model shows which terminals to use.
  6. Set the open time and test. Set the door-open delay, add users and cards, then test the reader, the exit switch and a power cut.

Attendance

Need attendance from the same device?

Some face and fingerprint terminals record attendance and open the door. Plain access control readers only open the door.

If you need staff attendance reports, choose a terminal that does both, such as the FCAC-1K (attendance data to pen drive in Excel) or the FCA-01. For attendance only, see our biometric attendance machine buying guide and the attendance machine range.

Before you buy

A quick checklist.

  • What is the door made of: wood, metal, framed glass or frameless glass?
  • Is it a single or double door, and which way does it open from the inside?
  • Is the reader indoors or exposed to rain and sun?
  • Card, PIN, fingerprint or face? How many people will use it?
  • Is there a 230 V socket near the door for the power supply?
  • Is the door a fire exit? Then add an emergency break-glass.
  • Do you also need attendance reports?

Answer these in the kit builder, or send us a photo of the door.

FAQ

Questions, answered.

What do I need for a complete access control system on one door?

Four parts: a reader (card, PIN, fingerprint or face), an electric lock (EM lock, drop bolt or electric strike), an exit switch on the inside and a 12 V access control power supply. Some doors also need a bracket so the lock fits.

Which bracket do I need for my EM lock?

No bracket for most framed doors that open away from the lock side. A Z + L bracket if the door opens towards the lock side, an L bracket for narrow frames, a U bracket for frameless glass and a GG bracket for glass-to-glass doors with no frame.

Is a 600 lbs EM lock strong enough?

Yes, for most single office, cabin and glass doors. Choose 1200 lbs for heavy main doors, and the 1200 lbs double leaf lock for double doors.

Will the door open during a power cut?

An EM lock opens when power is lost (fail-safe). Drop bolts and electric strikes depend on the model. For a door that must keep working during power cuts, use a power supply with battery backup.

Can I use an EM lock on a frameless glass door?

Yes, with a U bracket that clamps the plate to the glass, or a GG bracket if there is no frame at all. A frameless glass door lock (DBFG-05) is another option.

Do I need an exit switch?

Yes. Every access-controlled door needs a way out without a card: a push button or a no-touch sensor on the inside. Fire exits should also have an emergency break-glass.

Will my old RFID cards work with a new reader?

Only if both use the same card type. Readers use either 125 kHz (EM) or 13.56 MHz (Mifare/IC) cards. Check the reader's product page.

Can the access control also record attendance?

Some face and fingerprint terminals do both, such as the FCAC-1K and FCA-01. Plain card and PIN readers only open the door.

Do you deliver across India and give a GST invoice?

Yes. Delivery is free across India, every order comes with a GST invoice, and payment is prepaid online by UPI, card or net banking.
