    3-SAC, the CRC continues to function without any degradation. If power is lost to the CRC, it can continue to operate on its own internal battery power. The CRC will continue to grant and deny access for a limited amount of time (refer to battery calculations in Appendix A), thereby eliminating the need for granting free access during a degraded period.

  • Page 15: Controls For Readers And Locks

    The CRC can accommodate two card readers (entry and exit) plus an associated electric door lock. The CRC can use an external 24 Vdc power supply or a CRCXF CRC Transformer (a 16.5 Vac transformer) to power continuous-duty locks.

  • Page 16: Crc Input Circuits

    Features and functions CRC input circuits Each CRC has two input circuits for use with access control and security devices. These are typically used for a door position sensor and a request to exit device. The input circuits can be configured for use with a switch, controlled by a receptionist, that manually unlocks the door.

  • Page 17: Access Levels And Schedules

    Schedules and holidays The CRC stores the schedules and holidays created in the ACDB program. Each schedule identifies specific times (in 15-minute increments) and days when access is granted.

  • Page 18: Database Capacities

    The CRC or CRCXM can store 1,200 schedules (255 per company) and 1,200 holidays (255 per company). The CRC stores up to 5,000 events per door, ensuring no loss of history. The CRCXM has additional memory and stores up to 20,000 events.

  • Page 19: User-Defined Unlock And Open Times

    User-defined unlock and open times Using the ACDB program, the administrator can control how much time a person has to enter or exit through a door. The CRC controls both the unlock time and door open time, and these can be set in the ACDB program.

  • Page 20: Crc Functions

    Features and functions CRC functions Construction mode The CRC can operate in a construction mode. In this mode, the building contractors use specially coded cards for gaining access before the system is fully operational. This mode is in effect before the CRC is programmed by the ACDB.

  • Page 37: Access Control Applications

    Chapter 4 Access control applications Summary The CRC is a powerful and flexible component of access control systems. While it is a central component of such systems, it cannot work in isolation. This chapter shows how the CRC interacts with other components and modules.

  • Page 38: Other Factors

    • ACDB/KDC operation Power supply The CRC is designed to operate on 24 Vdc. For this reason, we recommend that you include power from the panel with the SAC bus cable. You can use the panel 3-PPS/M or 3-BPS/M power supplies.
  • Page 39 From the computer modem to a 3-MODCOM via telephone lines The end result is that the ACDB database can be downloaded from the user’s computer to the system. Each CRC stores that portion of the database pertinent to its operation. Access control applications The remaining topics in this chapter discuss specific access control applications.

  • Page 40: Anti-Passback

    To implement anti-passback, a separate CRC is required at each doorway in the controlled partition. Each doorway requires an outside card reader. Strict and logged anti-passback applications also require an inside reader at every doorway.
  • Page 41 The control panel must contain a 3-SAC Security Access Control module. The 3-SAC module supports the SAC bus. Power for the CRC can be taken from the 3-PPS/M and routed with the data lines in a cable composed of two twisted-pair wires (the SAC bus).

  • Page 43: Central Monitoring Station

    When a reportable access event occurs, the event message travels from the CRC to the 3-SAC. The 3-SAC passes the message to the 3-CPU1 which executes a predefined command list. The command list specifies the details of the message that is sent to the 3-MODCOM for transmission to the CMS.
  • Page 44 Reporting access control events to a CMS depends entirely on programming and the creation of command lists. In essence, you must assign a command list to each CRC event you want to report. The command list contains the details of the message to be transmitted.

  • Page 52 This is suggested due to the length of cable from the cab to the electrical room. Two pairs of wires are used to connect the CRC to the control panel. The SAC bus requires one pair for data communication. One wire of the second pair is required to maintain a common ground between the control panel and the CRC.

  • Page 53: Emergency Exit Door

    If the door is opened without badging out, it causes an immediate alarm. Badging out bypasses the door for a specific period of time, so no alarm event occurs. A typical CRC application for emergency exit door is shown in Figure 4-6, below. Door...
  • Page 54 Access control applications The door contact is connected to the CRC via the input circuit. SDU programming In the SDU, you’ll need to define the input circuit for the door contact as follows: • Device type: Security P Monitor •...

  • Page 55: Handicap Access Door

    A person without handicap privileges would operate the door just as any other door. When a person with handicap privileges badges in, the CRC recognizes that the person has handicap privileges and provides two extra benefits. The first is giving the handicap person extra time to enter or exit the doorway before relocking the door.
  • Page 56 The additional card readers are wired to the standard card readers in parallel. SDU programming In the SDU, you’ll need to define the CRC relay device type as Access Door Motor Control. This will activate the door opener for the time specified by the ACDB.

  • Page 57: Maglock Peripherals

  • Page 64: Power For Continuous Locks

    30 seconds in every minute. Normally, power for the lock is taken from the CRC battery. However, for continuous locks there is not enough recharge time for the CRC battery to keep up with the drain. Consequently, the CRC must be configured so that an external power supply operates the lock.
  • Page 65 3-SAC Security Access Control module • 3-PPS/M Primary Power Supply module The 3-SAC module supports the SAC bus. Power for the CRC is taken from the 3-PPS/M and is routed with the data lines in a cable composed of two twisted-pair wires.

  • Page 66: Power For Intermittent Locks

    30 seconds in every minute. In these applications, the CRC battery can provide the power needed to operate the lock. The CRC is powered by the 3-PPS/M. It uses this power source to charge an internal 1.2 Ah sealed lead acid battery. The battery then provides the power needed to operate the door lock..
  • Page 67 The figure shows the charging power coming from the 3-PPS/M in the control panel. The access control system requires a 24 Vdc power supply to power the CRC and to charge its battery. The 3-SAC connects to the CRC through the SAC bus.

  • Page 68: Power From An Ac Source

    Power from an ac source Description of the application By ac power, we mean that the CRC provides the power to operate the electric door strike or maglock by using a 16.5 Vac transformer (model CRCXF). This supply can provide continuous power to the door strike or maglock, and also power the CRC.
  • Page 69 SDU programming ACDB/KDC operation Figure 4-13: CRC using ac power The figure above shows the CRC power coming from the 16.5 Vac transformer. The 3-PPS/M power supply coming from the control panel simply passes through the CRC. The 3-SAC connects to the CRC through the SAC bus.
  • Page 70 • 3-PPS/M Primary Power Supply module The 3-SAC module supports the SAC bus. Power for the CRC is normally taken from the 3-PPS/M and is routed with the data lines in a cable composed of two twisted-pair wires. In this case the power from the 3-PPS/M is connected to the CRC terminals, but internally bypassed.

  • Page 71: Power From A Remote Source

    Power from a remote source Description of the application By remote power, we mean that the CRC provides the power to operate the electronic door strike or maglock by using a remote dc power supply. This additional power can provide continuous power to the door strike or maglock.
  • Page 72 Figure 4-15: CRC using remote power The negative side of the 3-PPS/M power supply coming from the control panel connects to the CRC (and to all other CRCs). The positive side is broken and the remote power supply picks up the load.
  • Page 73 The 3-SSDC module supports the SIGA loop, which supervises the remote power supply The 3-SAC module supports the SAC bus. Power for the CRC is normally taken from the 3-PPS/M and is routed with the data lines in a cable composed of two twisted-pair wires. In this case the power from the 3-PPS/M is simply passed through the CRC.

  • Page 74: Remote Controls

    Remote controls Description of the application In any access control system, a card reader and CRC can be used to operate devices that are completely remote from the CRC. In such cases the CRC simply creates an access event and passes it to the 3-SAC for processing by the 3-CPU1.

    A cardholder badges in at a card reader. The card reader reads the card number, which consists of 26 to 38 bits of data. The card reader transmits the data to the CRC via the Data 0 and Data 1 lines. The CRC receives the data. When data stops, the CRC begins processing the number.
  • Page 109 Operation is active, the CRC checks to see if the present time is within the cardholder’s second access level schedule. A schedule is a collection of 15-minute segments in a week. These segments tell the system whether a cardholder is permitted access at a door at a particular day and time.
  • Page 110 12. PIN required for disarm If the CRC partition is armed, the CRC checks the PIN required for disarm option. If this option is set, the red LED on the reader will flash slowly to inform the cardholder to enter the PIN. If the PIN is successfully entered, processing continues.
  • Page 111 If this option is not in effect, processing continues. If it the card disarm option is set, the CRC sends a request to the 3-CPU1 to disarm the CRC partition. When the 3-CPU1 confirms the request by disarming the...
  • Page 112 20. Bypass time If a door is opened and there is a value in bypass time, the CRC bypasses the door contact for the specified time. (The door must be configured with an open or exit device with a bypass option.) If the door is opened when this timer is zero a security event is created.

    Operation Lock power CRC lock power control Lock power output is controlled by the CRC. It is turned off automatically when the CRC detects a low battery condition on its internal 1.2 Ah battery. 3-CPU lock power control Lock power is also controlled by the 3-CPU1. Doing so helps conserve the panel battery power if the panel powering the CRC loses ac power.
