Section 1
Introduction
The Model 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 6.2
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 sychronizated
modules when using Amseco, Faraday, Gentex, System Sensor, or Wheelock
synchronization appliances.

3.2 Signal 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.
Section 5 shows connections to specific Silent Knight fire alarm control units.
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
interupting 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.
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 cir-
cuits. Use the 5495 trouble relay when it is necessary to monitor trouble conditions and active alarm con-
ditions at the same time.
Section 7 explains the significance of each trouble condition in more detail.
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.

P/N 151161 5
3.3 Notification 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:
You can select which input controls which output, and which inputs are Class A and Class B
using the 7-position DIP switch on the printed circuit board. Section 4.8 for DIP switch
settings.

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.
4.1 Mounting
Mount the 5495 in locations that meet the following temperature and humidity requirements.
Do not expose the panel to conditions outside these ranges.
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.
Temperature 0oC-49oC (32oF-120oF)
Humidity 10%-85% at 30oC (86oF) noncondensing

Installation
P/N 151161 7
4.2 Wire 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.
Figure 4-1 Sample Wire Routing
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.

4.3 Current Requirements (Standby and Alarm)
4.3.1 Current 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.
4.3.2 Current Drawn from Battery
Batteries used with the 5495 must not exceed 33 AH, such as. Batteries larger than 7 AH will
not fit into the 5495 cabinet and must be housed in the AB-33 Accessory Battery Cabinet. 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.

Installation
P/N 151161 11
4.4.1 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 contactthat is closed whenthe 5495 has powerand there are no trouble conditions.
Figure 4-3 Trouble Relay Connection Example
4.5 Notification Appliance Wiring
Note:Not all devices can use the sync feature. Be sure to check Table A-1 Appendix A to ensure the device you
have chosen will work with this feature.
4.5.1 Class A Supervised Wiring
Figure 4-4 shows how to wire for Class A input and output supervision. Use in/out wiring
methods for proper supervision. (Refer to the Appendix for notification appliances compatible
with the 5495.)
Class A Output Notification Circuits
The configuration shown in Figure 4-4 shows two, 3 A devices wired as Class A. When using
the outputs as Class A circuits, loop the wiring back to the corresponding circuit pair. For
Class A wiring, no external EOL is necessary since it is built into the 5495 board.
Must be connected to
a power limited source

Class A Supervised Input Circuits
The configuration shown in Figure 4-4 shows Class A supervised wiring from a fire alarm
control panel to the Model 5495 board. Pay close attention to the polarities when wiring a
panel to the 5495 and follow these requirements:
• When wiring to Terminal 18 on the 5495, you must use two separate wires. Do not loop a
single wire or twist two conductors together.
• Do not use notification appliances on Class A circuits connected to a 5495 for input. The
5495 will detect voltage across the input circuits, but is not designed to pass the added
current load from notification appliances.
Figure 4-4 Class A Supervised Input/Output Connections
4.5.2 Class B Supervised Wiring
Figure 4-5 shows how to wire for Class B input and output supervision. Use in/out wiring
methods for proper supervision (Refer to the Appendix for notification appliances approved
for use with the 5495.)
Class B Output Notification Circuits
Figure 4-5 shows four, 1.5 A devices wired as Class B.
Place a 4.7k ohm EOL resistor (provided) at the end of each circuit to enable supervision
when using all outputs as Class B notification appliance circuits. The 4.7k EOLs must be
wired to the terminals whether or not you are using all output terminals.

Installation
P/N 151161 13
Class B Supervised Input Circuits
Figure 4-5 shows Class B supervised wiring from a fire alarm control panel to the Model
5495.
Use an EOL resistor as shown to enable notification appliance circuit input supervision. Some
panels use EOLs that have a different value from the 4.7k ohm EOL resistor used by the 5495.
In this case, the EOL must be UL listed for the fire alarm control panel (not the 5495).
Figure 4-5 Class B Supervised Input/Output Connections
4.6 Ground Fault Detection Enable/Disable Jumper
In some cases the ground fault detection feature on the 5495 may interfere with the ground
fault detection feature of the main control panel in the system. To disable the ground fault
detection feature on the 5495, place the jumper block on J1, across Pins 1 and 2 (see Figure
4-2).

4.7 Battery Connection
You must use two 12 volt batteries with the 5495. Use two 12 VDC, 7 AH gel cell batteries in
series, such as the, inside the 5495 cabinet. For batteries larger than 7 AH (not to exceed 33
AH)use AB-33 Accessory Battery Cabinet. It is recommended that you replace the batteries
every five years. The following steps and diagram explain how to connect the batteries.
1. Connect the black wire to the negative (-) side of Battery #1.
2. Connect the jumper wire provided (P/N 140694) from the positive (+) side of Battery #1
to the negative side of Battery #2.
3. Connect the red wire to the positive (+) side of Battery #2.

4.8.1 Selecting the Standard Input/Output Configurations
Figure 4-7 and Figure 4-8 show the position of each switch for the non-sychronized input and
output configurations. The position of Switches 4 and 5 does not affect the relationship of
inputs to outputs.
Note:The 5495 checks switches 1, 2, 3, and 6 only when powering up the 5495. If you change these switch
settings, you must remove both the AC power and the battery to make the 5495 recognize the new settings.

Special Note for Input/Output Configurations That Select ANSI Temporal-Coded Outputs
The DIP switch settings marked with an asterisk (*) in Figure 4-7 and Figure 4-8 are designed
to produce ANSI temporal-coded outputs from a constant input. The figures shown below
compare the output patterns of configurations before and after the addition of this feature.
With this new feature, a steady signal can produce the pattern shown above for panels not
previously able to do so.
Note:The 5495 can also produce temporal patterns if the inputs are non-ANSI temporal configurations.

4.8.2 Selecting Synchronized Output Configurations
The following sections describe how to configure the 5495 as a synchronization power
expander for Amseco, Faraday, Gentex, System Sensor, or Wheelock synchronized horn/
strobe appliances.
Note:In order for the synchronization feature to operate properly, make sure you have set the DIP switches for
the proper manufacturer. See Sections 4.8.2.1, 4.8.2.2, or 4.8.2.3.
4.8.2.1 Selecting Synchronized Faraday Configurations
To select the input/outputs for Faraday synchronized appliances, set the DIP switches as
shown in Figure 4-9.
Figure 4-9 Faraday Synchronized Configurations
4.8.2.2 Selecting Sychronized Gentex Configurations
To select the input/outputs for Gentex synchronized appliances, set the DIP switches as shown
in Figure 4-10.
Figure 4-10 Gentex Synchronized Configurations
Important!
For all synchronization options, input 1 is the strobe input and input 2 is the audible input. The signals to input 1 and input 2
must be DC signals for the synchronization patterns to work properly. When it is desired to activate both strobes and audibles,
input 1 and input 2 must be active. If it is desired to only activate strobes, then input 1 must be active and input 2 must be
inactive. The audible can be deactivated and reactivated at any time by changing the signal at input 2 as long as input 1
remains active. If input 1 is not active, then input 2 is ignored.
