(IV)Quick tips to use locking management system

1.Locking management system comprises those components as following:

  • a. RFID card locks (quantities = guest room and public door) and good quality AA batteries*4 (customers should purchase them locally) for each lock --- to open the door
  • b. Wall reader (optional component) --- normally it will be installed on the public door.
  • c. USB Key card encoder|Reader|Writer (one for each front desk PC ) --- to issue all kinds of cards
  • d. Key cards (quantities = 5 times as much as the amount of guest rooms) --- to open the door lock / pass
  • e. Handheld terminal PDA(one per hotel, optional component) --- to get the time of locks or access readers;
    to set the time into locks or access readers; to program the locks or access reader as installation card; to get the firmware information from locks or access readers; to get the open record / trail audit from locks or access readers
  • f.USB dongle|soft dog --- a key to run locking management software as double security
  • d.Locking management software --- to manage whole locking system. (English and Chinese version available, other languages have to be translated by local customers)

2.to confirm handle back set and door thickness and door open direction:

    Adaptive door thickness:30mm to 55mm for M3/M3P mortise(back set=60mm); 40mm-55mm for M1/M1P mortise (back set=70mm)

3.to precisely install the lock and strike plate/strike box based on hole making template / fitting template

4.Three major procedures to start

    Procedure 1: to do the settings in the locking management software.
  • -> Install hotel management software with valid registration number;
  • -> Make a new authorized card and mark it with a sticker. This is the most important management card. Please do not lose it;
  • -> Create hotel buildings and rooms.
  • -> Set room type and do the room settings;
    Procedure 2: to program locks and set initial information into locks or access reader
  • -> Download room and building structure basic information to hand held terminal PDA(If you do not have this device, skip this step!)
  • -> Issue installation cards for each room and each public door from locking management software;or set the hand terminal as installation cards issuer.
  • -> Swipe authorized card and then swipe installation card on each lock, therefore, then room basic information is set into the locks or access readers.
  • -> Issue a clock card from locking management software (notice:the time in the clock card is fixed which cannot move as real time goes by, so we must do the following step as soon as possible);or set the hand terminal as clock card mode (the time in hand terminal can go as real time).
  • -> Swipe authorized card and then swipe clock card(or via hand terminal) on each lock, therefore, the time is set into the locks or access readers.
    Procedure 3: to issue guest card with start time (check-in time) and end time (departure time) when check-in; to clear card or check-out without card when check-out via front desk PC / Reception Desk.
