Safety Information and UL Requirements

This portion of the document provides information about designing a security system using Velocity software and Mx Series controllers that meets certain UL standards.

Electrical Safety Information

To prevent electric shock, you must observe common-sense precautions when working with the high-voltage AC input power connections and the standby battery pack connections to a controller. For example:

• Before removing or replacing fuses, turn off the main power leading into the controller.

• Before working on the power supply connections of a controller, turn off the main power leading into the controller.

No special precautions are required when working with the Class 2 limited-power connections which supply low-voltage power to other devices such as readers. (When you create these connections, you are not working directly with bare live wires. Instead, the ends of the wires are attached to plastic terminal blocks on the controller, MATCH board, or reader.) However, when routing the wires for the Class 2 limited-power connectors, make sure that you maintain a safe separation of at least 0.25 inches from the wires for a
controller’s AC input power and the standby battery pack. For an illustration of this principle, see Figure 2-3, in section “Separation of Circuits”.

Class 2 Limited-Power Connectors on an Mx Controller

The Mx controller can be configured to control either 2, 4, or 8 doors, depending on which model of the Command and Control Module (CCMx) is installed. It can be ordered with either SNIB2 or SNIB3 functionality.
The Mx controller’s main board has the following Class 2 limited-power connectors (listed here in clockwise order starting from the lower left side):

• The four 3-wire alarm relay terminals generate different types of alarms (1 = General alarm, 2 = Duress alarm, 3 = Tamper alarm, and 4 = Trouble alarm), which can be handled separately to meet your specific needs.

• The Ethernet connector (and its associated DIP switches) enables you to connect to a LAN/WAN and securely communicate with the Velocity server.

• The Expansion Board Connector is used to link any expansion boards mounted in the controller’s enclosure to the controller’s main board (using a flexible EBIC5 ribbon cable).

• The 3-wire Door Relay terminal blocks (one for each door) are rated 30VDC at 5 Amps, and are used to control externally powered door access devices such as magnetic locks and electric strikes.

• The 3-wire Door Input terminal blocks (one for each door) are used for analog inputs, such as multi-state alarm inputs through the line modules, and two-state outputs such as magnetic locks and electric strikes.

• The 5-wire MATCH terminal blocks (one for each door) are used for connecting the wiring from ScramblePad keypads or readers (through the MATCH2 Reader Interface Board). These are digital circuits which support daisy-chain connections to multiple devices on the same circuit.

• The 6-wire Wiegand terminal blocks (one for each door) are used for connecting the wiring from a 12VDC keypad or reader with a Wiegand interface. These are designed to support a variety of 125 kHz and 13.56 MHz readers and credentials. For more information, see “Connecting Exit Readers to Unused Wiegand Terminals on Mx-2 or Mx-4 Controllers”.

• The 5-wire SNIB2 RS485 Terminal (and its associated DIP switches) enables you to securely communicate with downstream controllers on a private network (which is managed by the same Velocity server).

• The 3-pin Tamper Switch connector attaches to the corresponding 5-sided connector for the wiring of the plunger-style contact switch that indicates whether the door of the metal enclosure is closed or open.
  For more information about the wiring for this device, see the Mx Quick Installation Guide sticker on the inside of the controller enclosure’s door, Figure 2-2, and “Separation of Circuits”.

Class 2 Limited-Power Connectors on an Mx-1 Controller

The Mx-1 controller is a 1-door controller which is packaged in a compact plastic case, and can be powered by either PoE+ or DC power from an external power supply. (Its light weight and small size provides more flexibility when deciding where to install it.)

The Mx-1 controller’s main board has the following Class 2 limited-power connectors (listed here in clockwise order starting from the middle of the left side):

• One 6-pin RS-485 Controller Bus terminal block which can be used to create a chain of controllers, where the first (master) controller communicates directly with the Velocity Server using its Ethernet connector, and the other (downstream) controllers communicate along the chain using RS-485 wiring. Otherwise, an Mx-1 controller can communicate directly with the Velocity Server across a network using its POE+ Ethernet connector.

• One Expansion Board Connector (which is used to link any expansion boards mounted in the controller’s enclosure to the controller’s main board, using a flexible EBIC5 ribbon cable).

• Two 8-wire terminal blocks (for connecting the wiring from a 12 VDC keypad or reader with a Wiegand interface). These are designed to support a variety of 125 kHz and 13.56 MHz readers and credentials.

• One 5-wire terminal block (for connecting the wiring from a 12 VDC keypad or reader with an OSDP RS-485 interface).

• Two 3-wire analog Door Input and Aux. Input terminal blocks (for the line modules used to supervise doors, tamper circuits, and RQE devices).

Two 3-wire Door Relay and Aux. Relay terminal blocks are used to control the door’s access device (such as a magnetic lock or an electric strike) and an external alarm or auxiliary device.

• The Ethernet / POE+ connector (and its associated DIP switches) provides up to Gigabit data connectivity for secure communication with the Velocity server, and can be used to power the controller (and some attached devices) through Power Over Ethernet Plus with a nominal 25.5 Watts of input power. The POE+ power source should be UL 294 listed.

For more information about the wiring for this device, see the Mx-1 Quick Installation Guide provided with the controller, Figure 3-2 , and “Separation of Circuits” .

It has the following Class 2 limited-power connectors (listed here in clockwise order starting from the upper right side):

• Two 6-wire reader terminal blocks (on the upper right) enable you to connect readers which have the Wiegand interface.

• Two 3-wire P1 and P2 connectors (along the bottom) each provide 250 mA at 5VDC to power additional devices.

• The 5-wire DTRAC terminal block (on the left side) is used to connect to a DIGI*TRAC or Mx controller. (The Mx-1 and Mx-1-ME controllers do not have a MATCH connector.)

• The 5-wire KEYPADS terminal block (on the left side) is used to connect to one or two ScramblePads. This provides a digital circuit which enables you to daisy-chain multiple devices (such as a required entry reader and an optional exit reader for a door).

For more information about the wiring for this device, see “MATCH Reader Interface”, Figure 1-38, “MATCH Connections (MATCH2 Shown)”, and “Connecting ScramblePad and MATCH Interfaces”.

Class 2 Limited-Power Connectors on the DS47 Line of Readers

The DS47L line of readers includes many different models with a variety of features. For more information, see Table 1-11, “ScramblePad Types”, in section “Scramble Pads”.

Models that include an integrated MATCH2 interface have the same Class 2 limited-power connectors as the MATCH2 Reader Interface Board (which are explained in the previous list).

For more information about the wiring for these devices, see “Setting Up a DS47L ScramblePad/ScrambleProx” , and “Wiring the ScramblePad”.

Class 2 Limited-Power Connectors on the PS2 Power Supply

The PS2 Power Supply can power one or two heavy-duty locks/strikes or other powered devices. (Power to these devices is triggered by outputs from a controller, which are connected to inputs on the PS2.) It also includes a power connector for locally powering one or two ScramblePads at the door being controlled.

The PS2 has the following Class 2 limited-power connectors (listed here in clockwise order starting from the upper left corner):

• The 3-wire INPUT 1 and INPUT 2 terminal blocks are used to connect to door relay terminals on a controller.

• The 3-wire POWER 1 and POWER 2 terminal blocks are used to power a 24VDC electric lock or strike which secures a door. NOTE: Because the PS2 includes multiple 24VDC battery packs, these connectors will be Class 2 power-limited only if a CL2 Power Limitation Board is added to the PS2.

• The 3-wire unpowered RELAY 1 and RELAY 2 terminal blocks can be used to connect to other devices, so they are also controlled by INPUT 1 and INPUT 2.
  

Power Limitation Board

This board acts as a surge protector to ensure that the controller’s keypad/MATCH terminal blocks (with a maximum of 1.5 Amps at 28 VDC) maintain their Class 2 power limited level of safety. This board can also be used to ensure that a PS2 power supply’s POWER 1 and POWER 2 terminal blocks maintain their Class 2 power-limited level of safety.

UL Requirements

Velocity is flexible software that can control a wide variety of hardware components, enabling you to design a custom system that meets your particular security needs. The topics in this section provide information about designing a security system using Velocity software and Mx series controllers that meets certain UL standards.

General UL Information

UL is an independent safety science company that develops safety-related standards, and tests products to determine whether they meet a specific standard so they can be certified as UL-listed. There are various UL standards related to security systems or their components, such as UL 294, the Standard for Access Control System Units, and UL 1076, the Standard for Proprietary Burglar Alarm Units and Systems.

The UL-listed Velocity System may be comprised of the following components: Central Supervisory Station, M1N, M2, M8, M16, Mx, Mx-1, DS47L, DS47L-HI, DS47L-SPX, DS47L-SPX-HI, Power Limitation Board (CL2), PS2, DTLM1, DTLM2, DTLM3, MELM1, MELM2, and MELM3. The M2, M8, M16, and Mx controllers may employ the following expansion boards: MEB/BE, AEB, REB8, SNIB, SNIB2, and SNIB3.

UL 1076 compliance requires use of a listed reader. UL has verified compatibility of the following Identiv TS readers with the Mx-1 controller: 8210, 8230, 8330, and 8336.

Wiring methods shall be in accordance with the National Electrical Code (ANSI/NFPA70), Canadian Electrical Code (C22.1), local codes, and the authorities having jurisdiction. All cabling and wire used must be Listed or Recognized AWM wire, suitable for the application. Class 2 or 3 conductors must be segregated from electric light, power, Class 1 conductors, non-Class 2 or 3 signaling conductors, battery backup, and medium-power
network-powered broadband communications-circuit conductors.

When using the initial version of the SNIB3 communications board (which has a serial number of the form SNIB3-S-nnnnn), surge protection must be provided for the master SNIB3 in each chain of connected controllers, using the Sankosha Guardian Net LANCAT5e-P+ surge protection device. For details, see “Providing Surge Protection for a Master SNIB3”.

The system shall not be installed in the fail-secure mode unless permitted by the local authority having jurisdiction, and it shall not interfere with the operation of Listed panic hardware. The use of panic hardware has not been evaluated by UL.

For proprietary burglary system use, all status changes at the protected premise must be programmed to cause both an audible and a visual annunciation at the central receiving station, and an acknowledgement signal and local annunciation must be programmed from the central receiving station to the protected premise.

UL 1076 Acknowledgement Signal

The acknowledgement signal sent from UL 1076 is an audible and/or visual signal that is sent to the subscriber by the central station to notify the subscriber that a signal has been received indicating that the protection system has been properly armed. The acknowledgement signal can be sent manually or automatically.

Prerequisite: Before looking into the instructions on how to implement the acknowledgement signal/local annunciation, ensure that the Touch Secure reader is connected to the Wiegand interface of the controller and configured accordingly in Velocity.
