Black Dorset hotel card lock with lever handle on a wooden guest room door — A Dorset hotel lock on a guest room door; the lock shown may differ from the DG 100 HL.

On the room door

A battery lock, and no cable to the door

The guest taps the card at the reader on the outside of the lock. The lock checks the room and the dates written on the card and opens. Locks run on batteries, so there is no cabling to run to each room.

DG 100 HL: card and key, 13.56 MHz Mifare cards, low battery alarm, privacy mode.
The mortise must suit the lock, so share the door thickness and the existing cut-out.
Records stay in the lock; the DG DTR-01 collects them for audits.

How it works

In 5 steps

01Check-inThe receptionist selects the room and the stay dates in the hotel lock software on the front desk PC.
02EncodeThe card encoder, on that PC by USB, writes the room and validity period onto a Mifare guest card.
03OpenThe lock checks the card is valid for this room at this time and releases the latch. No cable runs to the door.
04Power onInside, the card in the energy saver turns room power on; removing it switches power off.
05CheckoutThe card's encoded validity expires. Card return, early revocation and audit depend on the chosen lock system.

System diagram

An offline system: the card carries the access

Only the front desk is wired. Locks run on batteries and read what the encoder wrote on the card.

Buying guidance

The DG 100 HL lock, DG ENC encoder and DG ERS energy saver are all specified for 13.56 MHz Mifare cards, and the DG SW01 lists the DG ENC and a front desk PC. Confirm the exact combination with technical sales when you order.

Planning

One lock family per property

Each family is specified with its own encoder and software.

Dorset or ZKTeco, not both

Dorset locks, the DG ENC encoder and DG SW01 software work as one system on 13.56 MHz Mifare cards. ZKTeco hotel locks name their own software and encoders. A mixed property usually means two front desk systems.

More modelsOther models for each part

A working system needs card locks on the guest room doors, a card encoder at the front desk, the hotel lock software that drives it, and a stock of guest cards. Energy savers and audit tools are optional. The Dorset locks, encoder and energy saver are all specified for 13.56 MHz Mifare cards; confirm the exact combination with technical sales when you order.

Details

Software, installation and growth

Software

The Dorset DG SW01 hotel lock software is supplied on a flash drive for the front desk PC, alongside the Dorset DG ENC USB card encoder. In a typical hotel lock workflow, this is where you set up rooms, issue guest and staff cards, and review opening records collected from locks. Confirm the current version’s features with technical sales before planning your front desk process around it.

The ZKTeco hotel locks name their own software in the catalogue specifications: ZKBiolock for the SL02-LH190H, ZKBioHLMS for the SL02-ZL140H, and the ZKBiolock Hotel Lock System with ZKBiosecurity 3.0 for the LH6000. Their encoders are named too (CR60W for the SL02-LH190H and D147-H for the SL02-ZL140H). That software and those encoders are not listed separately in the catalogue at present, so ask technical sales to quote the complete ZKTeco set if you prefer that family.

Installation considerations

Measure every door. Check thickness, the existing mortise and handing. The ZKTeco SL02 locks list a 43 to 63 mm door range; confirm the Dorset range for your doors with technical sales.
Door preparation. The carpenter adapts the mortise, drills for spindle and through-bolts, and fits the strike. Fire-rated doors must stay fire-rated.
Batteries and override. The ZKTeco locks list four AA alkaline cells; keep spares. The Dorset locks list card and key access, so control the mechanical key.
Emergency egress. Guests must always be able to leave by turning the inside handle, without a card.
Energy savers. An electrician wires the saver into the room distribution through a suitably rated contactor, with proper earthing.
Front desk PC. Keep the lock software on a dedicated, backed-up PC on a UPS.

Installation is done by your own carpenter, installer or electrician. SecurityGearHub supplies the hardware and software and can advise before you order.

Growing the system

More rooms. Add locks of the same family as you add rooms or floors.
Energy savers room by room. Many properties start with locks and add DG ERS savers as rooms are rewired.
Audit tools. Add a DG DTR-01 data retriever or DG MI DR data card from the hotel lock accessories range.
Networked locks. The ZKTeco SL02-ZL140H lists ZigBee communication through an SLG410 gateway, each supporting six locks.
Back-of-house doors. Offices, stores and staff areas can use separate smart locks; see the smart door lock buying guide.

Questions

Frequently asked

Do hotel card locks need wiring to the door?

No. Hotel card locks are normally battery powered and work offline, so fitting them is carpentry. Only the energy saver needs an electrician.

What happens if a guest loses a card?

Issue a replacement from the front desk. In most hotel lock systems the new card cancels the old one at the lock; confirm how your chosen system handles this.

Which guest cards do I need?

The Dorset locks and encoder are specified for 13.56 MHz Mifare, and the catalogue lists the DG MI S7 encrypted Mifare card. The ZKTeco locks list S50/S70 IC cards.

How does the energy saver work?

The Dorset DG ERS detects a Mifare card placed in it and turns the room power supply on or off. Keep always-on loads such as the fridge on a separate circuit.

Can I mix Dorset and ZKTeco locks in one property?

Not without checking first. Each family is specified with its own encoder and software, so a mixed property usually means two front desk systems.
