Section 1
Introduction
The 5495 is a notification appliance circuit and auxiliary power expander that provides up to 6 amps of filtered, 24 volt power for powering notification appliances and auxiliary devices. The 5495 provides its own AC power connection, battery charging circuit, and battery connections. Used with security and fire alarm control panels, the 5495 enables you to connect and distribute power to many more devices than your panel may normally allow.
•Input Configurations
The 5495 has two optically isolated signaling inputs that provide the signal connection from the main control panel to the 5495 (see Section 3.2 for more details).
•Output Configurations
The 5495 has four power-limited notification appliance circuits that can be configured in various combinations of Class A and Class B circuits (see Section 3.3 for details).
•Auxiliary Power Configurations
The 5495 has a dedicated, power-limited, auxiliary output that can be configured in two different ways. The auxiliary output can either be non-resettable (always on), or configured to switch off during the AC power failure to conserve the battery standby power. When the auxiliary power is configured to switch off, there is a 30 second delay before the auxiliary power is turned off after the AC power fails (see
Section 4.8.4 for details).
•Form C Trouble Relay
The 5495 includes a general trouble relay that will de-energize for any trouble situation. (see Section 4.4.1 for details).
•Earth Fault Detection
The 5495 monitors for earth faults to the system power or system ground. When detected, the system de-energizes the trouble relay and the input supervision relays (see Section 5.2 for details).
•ANSI Temporal Code
The 5495 provides two configuration options that will drive outputs with the ANSI temporal code if the inputs are on constantly (see Section 4.8.1 for details).
•Supports Synchronized appliances
The 5495 provides configuration options that will eliminate the need for synchronized modules when using AMSECO, Faraday, Gentex, System Sensor, or Wheelock synchronization appliances.

3.2Signal Input Terminals
Terminals 14 through 19 are polarized signal input terminals. They provide the signaling connection from the main panel to the 5495. See Figure 4-2 for more details.
The main panel supervises its notification appliance circuits used for communicating with the 5495 the same way it supervises ordinary notification appliance circuits. The signal inputs on the 5495 monitor the polarity of the voltage coming from the main panel’s notification appliance circuits to determine when to operate the notification appliance circuits on the 5495. The 5495 emulates the trouble behavior of a normal notification appliance circuit by interrupting the EOL supervision current for internal or output trouble conditions on the 5495.
Note that the 5495 will accurately sense the polarity of the main panel’s notification appliance circuits to drive the outputs whether or not the supervision connection is intact. The following situations will disconnect the EOL supervision at the signal inputs and indicate a trouble condition:
•Low AC power
•Low Battery condition
•Earth ground fault to the system power or system ground
•Auxiliary output power-limited condition
•EOL supervision trouble or power-limited condition at an output
Trouble conditions will not necessarily occur for both inputs when the trouble is specific to a particular output. Only the signal input controlling the output circuit that is in trouble will indicate a trouble condition. Below are examples where both inputs do NOT indicate trouble for a trouble occurring at only one output circuit.
Example 1: If input 1 controls all four outputs, a fault on any output will cause input 1 to indicate trouble. The fault does not affect input 2.
Example 2: If input 1 controls outputs 1 and 2, and input 2 controls outputs 3 and 4, a fault condition on output 3 or 4 will cause input 2 to indicate trouble. The fault does not affect input 1.
Note: Once the inputs are driven with forward polarity to activate the outputs, the main control panel will not be able to sense trouble conditions through its notification appliance circuit connected to the 5495 input circuits. Use the 5495 trouble relay when it is necessary to monitor trouble conditions and active alarm conditions at the same time.
Section 6 explains the significance of each trouble condition in more detail.

System Overview
3.3Notification Appliance Circuit Terminals
Terminals 3 through 10 are the notification appliance circuit output terminals. Each of the four circuits are rated at 3 amps, although you can only draw a total of 6 amps from the 5495. The 5495 outputs are short-circuit protected (power limited) according to UL 864 standards. Overcurrent indicators are yellow LEDs. The output voltage can vary depending on the load and input voltage.
The four power-limited NAC outputs can be configured as follows:
• Four Class B circuits |
• |
Faraday synchronized outputs |
|
• Two Class A circuits |
• |
Gentex synchronized outputs |
|
• |
One Class A and two Class B circuits |
• System Sensor synchronized outputs |
|
• |
Class B, ANSI temporal-coded circuits |
• |
Wheelock synchronization outputs |
•AMSECO synchronized outputs
One or both 5495 signal inputs control the NAC outputs, depending on the specific configuration setup. Possible configurations for the 5495 are:

Installation
Section 4
Installation
Before installing the 5495, the AC input must first be wired into the building’s main electrical power through the TB1 terminals (see Figure 4-2). Shut off the electrical power to the 5495, and then complete the general installation of the 5495 using the information in this section.
4.1Mounting
Mount the 5495 in locations that meet the following temperature and humidity requirements. Do not expose the panel to conditions outside these ranges. For use in indoor, dry environments.
Temperature |
0o C-49o C (32o F-120o F) |
Humidity |
10%-93% at 30o C (86o F) noncondensing |
When mounting on interior walls, use appropriate screw anchors in plaster. When mounting on concrete, especially when moisture is expected, first attach a piece of 3/
4-inch plywood to the concrete surface. Attach the 5495 to the plywood.
4.1.1Preventing Water Damage
Water damage to the fire system can be caused by moisture entering the cabinet through the conduits. Conduits that are installed to enter the top of the cabinet are most likely to cause water problems. Installers should take reasonable precautions to prevent water from entering the cabinet. Water damage is not covered under warranty.
151161 |

Model 5495 Distributed Power Module Installation Manual
4.2Wire Routing
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. Induced noise can interfere with telephone communication or even cause false alarms. Avoid pulling a single multiconductor cable for the entire system. Instead, separate high current input/output from low current. Separate power-limited from non-power-limited wiring.
Non-power-limited wiring must be enclosed in conduit.
Wiring within the cabinet should be routed around the perimeter of the cabinet. It should not cross the printed circuit board where it could induce noise into the sensitive microelectronics or pick up unwanted RF noise from the switching power supply circuit.
Note: The use of this knock out will reduce the number and/or size of batteries this cabinet can contain. Evaluation of space is important before using.

4.3Current Requirements (Standby and Alarm)
4.3.1Current Drawn From Host Panel
Table 4-1 shows the 5495 current draw requirements from the main control panel when the panel’s notification appliance circuit is in alarm. The current draw from the main panel when it is supervising the 5495 is the same current draw that would be present when the main panel supervises an ordinary notification appliance circuit.

|
4.3.2Current Drawn from Battery
Batteries used with the 5495 must not exceed 35AH. (33AH max. for FM (Factory Mutual) Installations). Batteries larger than 7 AH will not fit into the 5495 cabinet and must be housed in the RBB Remote Battery Box. See Section 4.7 for battery installation.
The following is the maximum current draw from the auxiliary power terminals for standby calculations. These currents assume 24 or 60 hours of standby time, followed by 5 minutes of maximum alarm current.
•195 mA for 24 Hour Standby Current
•39 mA for 60 Hours of Auxiliary Standby Current
The above numbers were calculated assuming the use of 7 AH batteries at 100% of rated capacity.
The total current of the 5495, plus all items powered from it, must not exceed 6 A when the panel is in alarm. Use Table 4-2 to ensure that the current does not exceed
6 A and, that the desired amount of standby is possible for the battery intended for use with the 5495.

Model 5495 Distributed Power Module Installation Manual
4.4.1Common Trouble Relay
The 5495 has a Form C trouble relay built into Terminals 11-13. The relay provides a normally open and a normally closed contact, both of which are rated at 2.5A. The trouble relay will deactivate under any trouble condition.
A typical application of the trouble relay is to connect the 5495 normally closed (N.C.) contacts in series with the EOL supplied with the fire alarm control panel. This will cause a trouble on the fire alarm control panel when the 5495 opens its trouble contacts.
Note: The N.C. contact is the contact that is closed when the 5495 has power and there are no trouble conditions.
Must be connected to a power limited source
