    2 to indicate trouble. The fault does not affect input 1. Once the PAD-3’s inputs and outputs are activated, the fire alarm control unit will not be able to sense trouble conditions through its notification appliance circuit connected to the PAD-3 input circuits. Use the PAD-3 trouble relay when it is necessary to monitor trouble conditions and active alarm conditions at the same time.
  • Page 6: Regulatory Standards

    The PAD-3 meets the class A requirements of the Code of Federal Regulations (CFR 47), Part 15, subpart J, for electromagnetic field emissions. Underwriters Laboratories The PAD-3 control unit is listed under UL Standard 864 for compliance to NFPA Standard 72 for fire service.

    When mounting the enclosure on interior walls, use appropriate screw anchors in plaster. When mounting on concrete, especially when moisture is expected, first attach a piece of ¾-inch plywood to the concrete surface. Attach the PAD-3 enclosure to the plywood. Consult the installation instructions included with the enclosure for proper mounting.
  • Page 10: Control Unit Mounting

    Before installing the PAD-3, the input must first be wired into the building’s main electrical power through the TB1 terminals. See Figure 2-2 on page 8. Shut off the electrical power to the PAD-3, and then complete the general installation of the PAD-3 using the information in this section.
  • Page 11: Wire Routing

    2.3 WIRE ROUTING Notes: All high voltage and non-power limited wiring must be kept separate from power limited wiring. A ¼” separation must be maintained, with high voltage and non-power limited wiring running in separate conduit openings from power wiring. To avoid induced noise (transfer of electrical energy from one wire to another), keep input wiring isolated from high current output and power-limited wiring.

  • Page 15: Battery Connection

    2.5.2 Battery Connection The PAD-3 requires a 24V sealed lead-acid battery set. The battery capacity can be from 7 to 15A.H. For battery sets larger than 7A.H., an enclosure with System 3 rails or a separate battery enclosure is required.
  • Page 16: Multiple Module Battery Connection

    One of the PAD-3 boards must have its charging circuit disabled. e) The PAD-3 with the active charger is limited to 1.5 amps of auxiliary DC power at terminals 18 and Two (2) battery connection splitters (part number 230-299203) are used on the battery set for proper connection.

    Style Y (Class B) Supervised Input Circuits Figure 2-8 shows Style Y (Class B) supervised wiring from a fire alarm control unit to the PAD-3 board. Use the control panel’s EOL resistor installed as shown to enable notification input supervision.
  • Page 18: Style Z (Class A) Input/Output Nac Wiring

    Style Z (Class A) Supervised Input Circuits The configuration shown in Figure 2-9 shows Style Z (Class A) supervised wiring from a fire alarm control unit to the PAD-3 board. Pay close attention to the polarities when wiring the unit and follow these requirements: When wiring to terminal 2 and 5 on TB2, you must use two separate wires.
  • Page 19: Auxiliary Power Supply Output

    2.5.6 Common Trouble Relay The PAD-3 board has a Form C trouble relay built into terminals 9-11 of TB2. The trouble relay will de- energize under a trouble condition. A typical application of the trouble relay is to connect the PAD-3 normally closed (N.C.) contacts in series with an EOL of a spare IDC or NAC or monitor input from a fire alarm control unit.
  • Page 20: Ac Fail Relay

    The ground fault reference for the PAD-3 may be different than the reference used by the fire alarm panel, resulting in a ground fault trouble at the panel even when none exists. To remedy this condition, the PAD-3 can have its ground fault detection circuit disabled.

    4.2 Door Holder Applications In a typical door holder application, the door holder power must be released to close all fire doors under the following conditions: Any active alarm condition. AC power is no longer present (to conserve backup battery power). To close the fire doors in these situations, wire a normally closed relay contact from the fire alarm control unit in series with the auxiliary power to the door holders.

    5. PROGRAMMING The PAD-3 functions are programmed with a 10-position DIP switch and six 3-position jumpers. The following section describes each setting. 5.1 DIP SWITCH SETTINGS The 10-position DIP switch allows you to select the following: • How long will the unit wait before indicating a loss of AC •...
  • Page 38: Selecting The Input/Output Configuration

    5.1.1 Selecting the Input/Output Configuration Figure 5-1 shows the position of each switch on the DIP switch for various input and output configurations. The position of switch 4 through 10 does not affect the relationship of inputs to outputs. Switch 1 OFF & Switch 2 OFF & Switch 3 OFF: Input 1 controls all outputs (Class B).
  • Page 39: Setting The Auxiliary Output

    Switch 4 on the DIP switch determines how the auxiliary power operates. The PAD-3 checks switch 4 only when powering up. If you change this switch, you must push switch SW2 momentarily to reset the unit to recognize the new switch setting.
  • Page 40: Setting The Input's Control Of Their Nacs

    5.1.3 Setting the Input’s Control of their NACs DIP switch settings 5 to 8 are designed to produce outputs from a constant on input. The figures shown below compare the output patterns of configurations before and after the addition of this feature. Slave Operation The Slave operation output follows the input and can be used when the fire alarm control unit NAC is steady, coded, march time, or temporal and the desired output is the same.
  • Page 41: Setting The Ac Power Fault Reporting Delay

    5.1.4 Setting the AC Power Fault Reporting Delay Normal selection for reporting loss of AC is 60 minutes. The OFF position is for test purposes only and the normal position for switch 9 is ON. For testing the Low AC reporting, you can temporarily turn switch 4 OFF without removing power. Remember to turn the switch ON when testing is complete.
