Section 1 Overview
1.1 5496 Description
The Model 5496 Intelligent Power Module provides additional power and notification circuits
to a Silent Knight addressable FACP. The 5496 can power all IntelliKnight compatible
notification appliances and auxiliary power modules.
The 5496 is capable of performing single or dual interlocking operations for pre-action and
deluge releasing systems. See Section 8.6 of FACP installation manual.
The 5496 has four output circuits that can be configured as notification or auxiliary power
circuits. Outputs are rated 3.0 A (6.0 A total for each 5496).
The 5496 is optically isolated, providing ground loop isolation and transient protection.
The 5496 provides configuration options that eliminate the need for sychronization modules
when using AMSECO, Faraday, Gentex, System Sensor, or Wheelock synchronization
appliances.
1.2 Agency Requirements
The 5496 has the same requirements as the main control panel. These requirements are listed
in Silent Knight addressable FACP Installation Manuals. Silent Knight Addressable FACP
Installation Manuals can be found on Silent Knight’s web site at www.silentknight.com.
1.3 About This Manual
This manual covers installation of 5496 hardware. Software configuration information is
contained in a Silent Knight addressable FACP Installation Manuals. Silent Knight
Addressable FACP Installation Manuals can be found on Silent Knight’s web site at
www.silentknight.com.

Section 2 Before You Begin Installing
2.1 What’s in the Box?
The Model 5496 ships with the following hardware:
• A cabinet with all hardware assembled
• Two keys for the 5496 front door
• Ten 4.7K ohm end-of-line resistors
Note: For UL installations Model 7628 4.7k end-of-line resistor (ordered separately) must be used.
• A battery wiring harness and jumper to wire batteries in series
2.2 Environmental Specifications
It is important to protect the 5496 control panel from water. To prevent water damage, the
following conditions should be AVOIDED when installing the units:
• Do not mount directly on exterior walls, especially masonry walls (condensation)
• Do not mount directly on exterior walls below grade (condensation)
• Protect from plumbing leaks
• Protect from splash caused by sprinkler system inspection ports
• Do not mount in areas with humidity-generating equipment (such as dryers, production
machinery)
When selecting a location to mount the 5496, the unit should be mounted where it will NOT
be exposed to temperatures outside the range of 0°C-49°C (32°F-120°F) or humidity outside
the range of 10%-93% at 30°C (86°F) noncondensing.
2.3 Preventing 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.

2.6 Calculating Current Draw and Standby Battery
This section is for helping you determine the current draw and standby battery needs for your
installation.
2.6.1 Worksheet Requirements
Follow the steps below to determine 5496 current draw and standby battery requirements.
Filling in the Current Draw Worksheet
Refer Table 2-4 in Section 2.6.2 to complete the following steps.
1. Add up the current draw for all auxiliary devices and record in the table at Line B.
2. Add up all notification appliance loads and record in the table at Line C.
3. For notification appliances and auxiliary devices not mentioned in the manual, refer to the
device manual for the current ratings.
4. Make sure that the total alarm current you calculated, including current for the panel itself,
does not exceed 6.0 A. This is the maximum alarm current allowable.
5. Complete the remaining instructions in Table 2-4 to determine battery size requirements.
2.6.1.1 Maximum Battery Standby Load
Table 2-3 shows the maximum battery standby load for the 5496 based on 24 and 60 hours of
standby. The standby load calculations of line J in the Current Draw Calculation Worksheet
(Table 2-4) must be less than the number shown in Table 2-3 for the battery size used and
standby hours required.
Table 2-3: Maximum Battery Standby Load
