Cautions and Warnings
READ AND SAVE THESE INSTRUCTIONS- Follow the instructions in this installation manual. These instructions must be followed to avoid damage to this product and associated equipment. Product operation and reliability depend upon proper installation.

• DO NOT INSTALL ANY SIMPLEX® PRODUCT THAT APPEARS DAMAGED- Upon unpacking your Simplex product, inspect the contents of the carton for shipping damage. If damage is apparent, immediately file a claim with the carrier and notify an authorized Simplex product supplier.
• ELECTRICAL HAZARD – Disconnect electrical field power when making any internal adjustments or repairs. All repairs should be performed by a representative or authorized agent of your local Simplex product supplier.
• EYE SAFETY HAZARD – Under certain fiber optic application conditions, the optical output of this device may exceed eye safety limits. Do not use magnification (such as a microscope or other focusing equipment) when viewing the output of this device.
• STATIC HAZARD – Static electricity can damage components. Handle as follows:
  • Ground yourself before opening or installing components.
  • Prior to installation, keep components wrapped in anti-static material at all times.
• FCC RULES AND REGULATIONS – PART 15 – This equipment has been tested and found to comply with the limits for a Class A digital device pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.
• SYSTEM REACCEPTANCE TEST AFTER SOFTWARE CHANGES – To ensure proper system operation, this product must be tested in accordance with NFPA 72® after any programming operation or change in site-specific software. Reacceptance testing is required after any change, addition or deletion of system components, or after any modification, repair or adjustment to system hardware or wiring. All components, circuits, system operations, or software functions, known to be affected by a change, must be 100% tested. In addition, to ensure that other operations are not inadvertently affected, at least 10% of initiating devices that are not directly affected by the change, up to a maximum of 50 devices, must also be tested and proper system operation verified.

Introduction to the Flex Amplifiers

Overview
The Flex amplifiers provide audio signals to system speaker circuits. The Flex Amplifier is offered in two versions, the Flex-35 and the Flex-50. Functionally, both amplifiers behave identically but the Flex-50 is capable of supplying an additional 15W of power over the 35W version. The maximum available output from the Flex-50 and Flex-35 is 50W and 35W, respectively. The load may be configured in any way so long as the maximum power output limit is not exceeded. Both amplifiers provide dual-channel capability with internal backup functionality. (All Flex Amplifiers described in this publication are listed in the next two sections.)

Setting the Baud Rate and Address

Overview
This section describes how to configure the amplifier’s baud rate and address using DIP switch SW1. Configuration is the same for analog and digital amplifiers.

Using DIP Switch SW1
The device baud rate and address is set via DIP switch SW1, which is a bank of eight switches. From left to right (see Figure 3, below) these switches are designated as SW1-1 through SW1-8. The function of these switches is as follows:

• SW1-1. This switch sets the baud rate for the internal communications line running between the card and the CPU. Set this switch to ON.
• SW1-2 through SW1-8. These switches set the card’s address within the FACP. Refer to Table 1 for a complete list of the switch settings for all of the possible card addresses.

Notes:

• You must set these switches to the value assigned to the card by the Programmer.
• The SW1 setting applies to audio controller slaves, including audio input cards.

Installing the Amplifier onto the PDI

Overview
The Flex amplifier assembly mounts on the PDI in an expansion bay. Up to two Flex Amplifiers may receive power from an XPS. If two Flex Amplifiers receive power from one XPS, then the XPS is solely dedicated to providing power for the Flex Amplifiers and cannot be used for supplying any other modules or I/O wiring off of the XPS I/O terminals. If the XPS is providing power for one Flex Amplifier, see Figure 4 for mounting placement. If the XPS is providing power for two Flex Amplifiers, see Figure 5 for mounting placement.

Mounting
Lower the amplifier into the bay by placing the two tabs on the back of the amplifier assembly into the two slots on the bottom of the bay. Then, use the connector on the backside of the Flex module to connect to the PDI as shown in Figure 6, below.

Amplifier Field Wiring

Overview
This section contains field wiring guidelines and illustrations for the amplifiers. These diagrams apply to both the Flex-35 and Flex-50. Wiring of optional NAC Expansion, Class A, and Constant Supervision NAC (CSNAC) modules is also covered in this section, as well as speaker circuit wiring distances. Since the Flex amplifiers allow self-backing operation, no wiring is required for configuring an amplifier for backup operation.

Troubleshooting

• Overview This section describes the messages that may appear on the display when using the audio amplifiers and their option cards.
• Card Missing/Failed The amplifier card is either not installed or is not at the system address specified by the Programmer.
• Wrong Card The wrong card is using the address specified by the Programmer as the amplifier card.
• Power Stage Trouble A power stage is not functioning properly. This means a signal is coming in but no signal is being outputted. Note that the supervision tone used to supervise the power stages will not be heard over the speakers. In systems configured with Power Conservation Mode, the power stage will not be supervised and a trouble will not be generated when the power stage is shut down.
• NAC Module Configuration Trouble The NAC expansion card or Class A card connected to the amplifier does not match the Programmer configuration for that card.
• Additional Troubles Additional troubles may be annunciated for shorts or opens on any of the following, each of which is supervised:
  • NACs (speaker circuits)
  • Amplifier inputs
  • DAR riser (communication failure)
• Using the Power Stage Fail Switches The power stage fail switches (SW2, SW3) can be used to test whether backup audio switching is working. To test the fail switches, press and hold SW2 (power stage 1) or SW3 (power stage 2) until the corresponding Trouble LED illuminates (20 seconds).
