Updated November 2026. An access-controlled door is a small system, not a single product. Buy only the reader and the lock and the job stalls on site for want of a bracket, an exit button or a power supply with backup. This checklist lists everything one access control door setup needs, what each part does, an example from our catalogue and how the pieces connect. We supply the hardware; wiring and setup are done by your own installer or electrician. Prices shown are current catalogue prices including 18% GST.

Reading and deciding: reader, terminal and controller
Reader or terminal
There are two ways to build a door. In a controller-based door, a simple reader outside the door sends the card number to a controller, which decides. In a standalone door, a terminal stores the users itself and switches the lock directly, which is fine for one or two doors.
For controller-based doors, browse access control card readers. The ZKTeco KR500 slim mullion reader (₹1,986 to ₹2,484) has Wiegand output to ZKTeco or third-party panels; its E models read 125 kHz cards and M models 13.56 MHz cards. The MORX RFR-107 proximity card reader is ₹1,968. For fingerprint at the door, the ZKTeco FR1500S flush-mount RS485 fingerprint reader is ₹10,680. For standalone doors, look at fingerprint, card and keypad terminals.
Controller, if used
A controller is worth it once you have several doors, want central reports, or need features like anti-passback or interlocking. The ZKTeco C3 Plus series comes in 1, 2 and 4 door models from ₹10,182 to ₹26,326 and per door it has inputs and outputs for the electric lock, door sensor, exit button, alarm and an auxiliary device. The MORX MAC-D4 four-door panel is ₹16,178 and the MORX MAC-D2 with Power Box is ₹25,242 if you want the controller and its power box together. See all access control panels and controllers.
Holding the door: lock and bracket
Lock
Most office doors use a 600 lbs (280 kg) EM lock. The ZKTeco EML280-5 EM lock with lock signal at ₹1,670 reports whether the door is actually locked; the 2-wire ZKTeco EML280-2 is ₹1,730. For double doors, the ZKTeco EML280D-2 holds both leaves at ₹3,560. For glass entrances, a drop bolt such as the ZKTeco F-BL43-5 with door status output (₹2,791) is a common alternative, and an electric strike suits doors that must stay locked during a power cut. Our EM lock buying guide covers holding force and fail-safe choices in detail.
Bracket
Check the door before ordering the bracket. A door with a usable frame header may need none. The MORX L bracket for 600 lbs locks is ₹299 and the matching Z bracket ₹556. For frameless glass of 10 to 15 mm, the ZKTeco MLB-280U U bracket (₹411) clamps the plate to the glass. Drop bolts on glass may need the MORX U Bracket for Drop Bolt Lock at ₹539. See all lock mounting brackets.
Getting out safely: exit button and break glass
Exit button
Every controlled door needs a way out from inside. The ZKTeco EX86-S stainless steel button on an 86 x 86 mm plate is ₹163 and the slim ZKTeco EX28-L for narrow frames is ₹164. The ZKTeco K1-1D touchless infrared exit button (₹571) suits clinics and labs, and the ZKTeco RC10 wireless remote exit button set (₹726) helps where running a cable is impractical. Browse exit buttons.
Emergency break glass
A break glass unit, usually green, sits beside the door and cuts lock power when someone breaks or presses it. With a fail-safe EM lock it gives a way out even if the controller or exit button fails. Fit one on every door on an escape route, and agree the arrangement with whoever signs off fire safety for the building. If you need one supplied with the rest of the door, list it in your quote request.
Knowing the door state: door-position contact
A door-position contact (a magnetic door contact) reports whether the door is open or closed. Without it, the system cannot warn about a door propped open or forced. A lock with a signal output, such as the EML280-5, reports lock feedback instead. Lock feedback and door position report different conditions. Check each signal and its intended controller input in the exact equipment documentation. Door contacts are listed under door and window sensors.
Power: supply with backup
Size the supply from the datasheets. The EML280-5 draws 0.43 A at 12V, a KR500 reader up to 70 mA, and the controller its own figure from its datasheet. Add them up, add at least 30% headroom, and choose a supply with a battery so the door stays locked during a power cut. Remember that a fail-safe lock releases as soon as the battery runs flat. Fire alarm release and emergency exit arrangements must follow local regulations; have a qualified installer design them from the exact equipment documentation. Browse access control power supplies.
Credentials: cards or tags
Match the card frequency to the reader. 125 kHz proximity cards suit 125 kHz readers; 13.56 MHz MIFARE readers need 13.56 MHz cards. The ZKTeco ID Thin Card (125 kHz, printable) is ₹11 and the ZKTeco ID Thick Card (125 kHz clamshell) ₹12. The MORX Proximity Key Fob is ₹48. Order a few spares for new joiners and lost cards. See access cards and tags.
How the parts relate
- Reader and controller: the reader sends the credential to the controller, over Wiegand or RS-485 depending on the models.
- Lock and controller: the controller switches the lock. Fail-safe or fail-secure behaviour, the relay contact to use and the lock supply come from the lock and controller documentation.
- Emergency release: break glass units and any fire alarm release must follow local fire and exit rules. Have a qualified installer design this part.
- Exit button: connects to the controller so exits can be logged.
- Door position and lock feedback: separate signals, each to the controller input the documentation names.
- Power supply with battery: sized for the locks, readers and controllers it feeds.
- Cards enrolled: users and cards are added in the controller software or web page.
In a standalone door, the terminal takes the controller’s place. This list shows how the parts relate; it is not a wiring diagram. Wire each door from the exact equipment documentation.
Where to go next
Use the table above as a starting list. Count reader and locking components for each door. Size shared controllers, power supplies and batteries for the system, and credentials for the people who need them. For multiple doors, mixed door types or bulk card orders, send the door count, door material and preferred reader type through our request a quote form and we will price the full list.
