Power / Battery

Use a battery that meets the following specifications and will provide at least 30 minutes of backup power in the event of an input power loss: 

• Recommended Battery Type: 12 VDC 5 Ah lead-acid battery
  
• Recommended Battery Size: 4” x 3.5” x 3” (L H W)
  
• Max Battery Dimensions: 6” x 5” x 4” (L H W)
  

A backup battery is HIGHLY recommended to prevent system failure in the event of an input power loss. When a backup battery is not used, a loss of input power will cause a loss of functionality. A backup battery must be installed in order to comply with UL 294. 

Add the 12V DC 5 Ah battery, attaching the wires from the battery to the circuit board battery terminal (illustration below). 

The battery connection is polarity sensitive, meaning that it has fixed positive and negative connections. From the onboard power supply, connect a red 18/2 wire from the positive (+) battery terminal to the positive (+) on the battery connector. Connect a black 18/2 wire from the negative (-) battery terminal to the negative (-) on the battery connection.

NOTE: DO NOT connect the backup battery until ALL wiring is completed and verified; incorrect wiring could cause damage to the product.

For information about connecting other wiring, such as power wires to third-party locks, readers, and other devices, see the respective manufacturers’ instructions.

Wiring

NOTE: For UL-certified wire installations, all wires running from a Red 2 Expander to a lock, strike, or reader device must be less than 98.5 feet (30 meters). 

• Strip the wire ends as required.
  
• Install the reader, and attach the wires, meeting your reader configurations. See Wiring Diagrams for additional information.
  
• Connect the wires between the door controller and locks and any other devices.

NOTE: For information about the connectors and their specifications and diagrams, refer to the appropriate wiring diagrams: Maglock, Fail-Secure Door Strike, and Fail-Safe Door Strike. 

 

Recommended Wiring Dimensions

Use 26 gauge minimum, 18 gauge maximum, stranded for general wiring. Wiring methods shall be in accordance with the National Electrical Code, ANSI/NFPA 70. Follow these recommended wiring sizes.

Wiring For	Recommended Size
Power Input	18 gauge 2 conductors (18/2) wire
Reader	22 gauge 6 conductors (22/6) wire
Strike / Maglock	18 gauge 2 conductors (18/2) wire
REX	18 gauge 4 conductors (18/4) wire
OSDP Reader	22 gauge 6 conductors Twisted-Pair (22/6) wire

 

Maglock/Exit Device Wiring Diagram

Locking devices can be either "fail-safe" or "fail-secure". A magnetic lock, or maglock, is a "fail-safe" locking device that consists of an electromagnet and an armature plate. The electromagnet portion of the lock is typically attached to the door frame, while a mating armature plate is attached to the door. The two components are in contact when the door is closed. When the electromagnet is energized, a current passing through the electromagnet causes the plate to attract the electromagnet, creating a locking action.

(A) Maglock: When installing a maglock, it is required to install an electronic REX (request to exit) device as well as a mechanical button at the same door (in case of electrical failure) for free egress. Run 18/2 wire connections from the maglock to the door controller. 

(B) REX/Exit Device: Mounted in the desired location with 18/5 wire running from the REX to the controller (18/3 wire if non-powered REX). Wire the REX to the controller and maglock. If using a powered REX, run to any 12VDC output on the controller. (If reporting is not needed in the system, simply eliminate the dashed wire.)

NOTE: It is not recommended to power third-party devices to the io board. Use a separate external power supply when wiring the exit device. 

(C) Jumper: Use the designated positive (+) or negative (-) board voltage out of NO and NC. If the jumper is off, the relay is a standard “dry contact”, needing a connection from common (C) and either NO (Normally Open) or NC (Normally Closed). In this diagram, the jumper is placed on the top (-) and center pin to operate the maglock.

 

Diode Setup

A diode is a standard semiconductor device integral to the safe and proper function of the door controller. It acts as a grounding tool, allowing the flow of current in one direction only. When a door strike is called/requested/sent, the coil sends a spike (also called “kickback voltage”) down the line with as much as 50,000 volts. Without a diode semiconductor, this kickback voltage would damage the control equipment. When properly installed, the diode keeps kickback voltage localized at the lock.

To protect your equipment against electrical kickback, the diode must be installed across the DC-powered lock, at the strike, between positive (+) and ground (-). DC voltage is polarized, meaning that it has fixed positive and negative connections. The diode must be installed in the direction shown in the illustrations: gray stripe to positive (+), black to negative or ground (-).

IMPORTANT: The diode MUST be installed as close to the lock as possible. The best scenario (if possible) is directly across the screw terminals on the lock. Another option is to splice the diode in parallel (shown in image two), connecting it to the positive (+) and negative (-) strike wires using dolphin connectors, and crimp the wires.

 

Locking Relay Wiring Diagram

(A) Diode: The provided diode MUST be installed when using a strike. Install at the strike with the stripe of the diode on positive (+) and the black on negative (-). 

(B) NC: Normally Closed—Used for maglocks (or strikes in fail-safe configuration). Connect the negative (-) of the maglock or strike to NC on the door controller.

(C) NO: Normally Open—Used for strikes in the fail-secure configuration. Connect the negative (-) of the strike to NO on the door controller.

(D) Jumper: Used to designate (+) or (-) board voltage out of NO and NC. If the jumper is off, the relay is a standard “dry contact” needing input into common. In this diagram, the jumper is placed on (-) side to operate the strike. 

 

Fail-Secure Door Strike Wiring Diagram

A fail-secure locking device remains locked when power is lost. An electric strike replaces the fixed strike faceplate often used with a latch bar. It normally presents a ramped surface to the locking latch allowing the door to close and latch just like a fixed strike. 

(A) Diode: The provided diode MUST be installed when using a strike. Install at the strike with the stripe of the diode on positive (+) and the black on negative (-). 

(B) NO: Normally Open - Used for strikes in fail-secure configuration. Connect the negative (-) of the strike to NO (Normally Open) on the Red 2 Expander. 

(C) Jumper: Use the designated positive (+) or negative (-) board voltage out of (NO) and (NC). If the jumper is off, the relay is a standard “dry contact” needing input into common. In this diagram, the jumper is placed on the negative (-) and center pin to operate the strike.

 

Fail-Safe Door Strike Wiring Diagram 

A fail-safe locking device unlocks when power is lost.

(A) Diode: The provided diode MUST be installed when using a strike. Install at the strike with the stripe of the diode on positive (+) and the black on negative (-).

(B) NC: Normally Closed - Used for strikes in fail-safe configuration. Connect the negative (-) of the strike to NC on the Red 2 Expander. 

(C) Jumper: Used to designate if positive (+) or negative (-) board voltage is supplied out of (NO) and (NC). If the jumper is off, the relay is a standard “dry contact,” needing input into common. In this diagram, the jumper is placed on the negative (-) and center pin to operate the strike in fail-safe configuration.

 

Door Position Sensor (DPS) Wiring Diagram

(A) DPS: The Door Position Sensor is mounted on the door frame in the desired location with a 22/2 wire running from the DPS to the controller. (When using two DPS sensors for double doors, wire them in series with only two conductors running back to the controller.)

(B) Input A: Rule-based inputs can be triggered by using the (A) input for something other than DPS.

NOTE: When the DPS input changes state, such as the door being closed and completing the circuit or opening the door and breaking the circuit, an input event occurs. A rule can then be set up to trigger a System Event based on this input event.
