PAD-4 Installation, Operation and Maintenance Manual
1. DESCRIPTIONS
The Model PAD-4 from Siemens Industry, Inc. is a
notification and auxiliary power expander that
provides up to 9 amps of 24 volt DC for powering
notification appliances and auxiliary devices. The
PAD-4 provides its own AC power connection,
battery charging circuit, and battery connections.
Used with a fire alarm control unit, this enables
you to connect and distribute power to many more
devices than your control unit may normally allow.
1.1 GENERAL DESIGN FEATURES
Inputs
The PAD-4 has two optically isolated inputs that
provide the connection from the fire alarm control
unit notification appliance circuit to the PAD-4. The
inputs also provide a connection for returning a
trouble condition to the control unit notification
appliance circuit.
The fire alarm control unit supervises its notification
appliance circuit used for communicating with the
PAD-4 the same way it supervises ordinary NACs.
The inputs on the PAD-4 monitor the polarity of the
voltage coming from the fire alarm control unit’s
NACs to determine when to operate the notification appliance circuit outputs. The PAD-4 emulates
the trouble behavior of a NAC by opening the EOL
supervision current for trouble conditions. Note
that the PAD-4 will sense the polarity of the fire
alarm control unit’s NACs to drive the outputs
whether or not the supervision connection is intact.
The following situations will open the EOL supervision at the inputs indicating a trouble condition:
• No or low AC power. For AC Fail reporting, refer to
Section 5.1.4 for configuration and response times.
• No and low battery condition.
• Ground fault to the output wiring.
• Auxiliary power supply output over-current
condition.
• NAC output open, shorted or over-current
condition on outputs associated with its input.
• Failure of the battery charger.
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.
Once the PAD-4’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-4 input circuits. Use the PAD-4
trouble relay when it is necessary to monitor trouble
conditions and active alarm conditions at the same time.
Notification Appliance Circuit Outputs
The PAD-4 has four dedicated, power-limited, NAC
outputs that can be configured as two Class A
(Style Z) or four Class B (Style Y) circuits. An
additional two Class A (Style Z) circuits are
available when the PAD-4-CLSA module is installed.
The PAD-4 provides four configuration options
that will set the outputs as slaves that will follow
the input. If the inputs are on constant, they may
be configured as ANSI temporal code, Sync
strobe/horn operation or carbon monoxide (CO)
alarms.
Each of the four outputs is rated at 3 amps,
though a total of 6 amps maximum (or 9 amps
depending on power supply) can be drawn from
the PAD-4 outputs. The yellow Output LEDs
(DS1-DS4) flash to indicate an open, shorted or
over-current condition on its associated NAC
Output. The yellow Output LEDs are on steady to
indicate activation of the associated NAC output.
Selection of which input controls which output,
and which inputs are Class A (Style Z) and Class
B (Style Y) is done using the 10 position DIP
switch on the printed circuit board. Refer to
Section 5 for DIP switch settings.
The PAD-4-CLSA module, optional for UL installations but required for ULC installations, provides an
additional two Class A (Style Z) notification appliance circuits to the PAD-4. When configured for
ULC operation, it also provides a Form A contact for
ground fault detection signaling. One PAD-4-CLSA
module can be mounted on the PAD-4. Refer to
P/N 315-050254 for more information.
Notes:
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.
Auxiliary Power Output
The PAD-4 has a dedicated, power limited,
auxiliary output that can be configured in two
1
Page 6
PAD-4
Installation, Operation and Maintenance Manual
different ways. The auxiliary output can either be
non-resettable (always on), or configured to
switch off when the AC power goes off 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 goes off. The
auxiliary power is for supplementary purposes
only if it is configured to switch off when AC is lost.
The Auxiliary Power Output is rated at 3 amps. Only
a total of 6 amps maximum (or 9 amps depending
on power supply) can be drawn from the PAD-4
outputs. The yellow Aux PS LED (DS5) will flash to
indicate an over-current condition on the output.
The LED will go off if the battery conservation
feature is active.
Common Trouble Relay
The PAD-4 includes a Form C trouble relay that will
de-energize for the following trouble conditions:
• No or low AC power (Refer to Section 5.1.4
for delay time settings).
• No and low battery condition.
• Ground fault to the output wiring.
• Auxiliary power supply output over-current
condition.
• NAC output open, shorted and over-current
condition.
• Failure of the battery charger.
AC Fail Relay
A normally energized relay will be de-energized
after no or low AC power without delay. A Form A
contact provides a local signaling (audible and
visual) of an AC fail at the protected premises.
Battery Charging and Supervision
The PAD-4 provides a battery charging circuit for
charging sealed lead-acid batteries. The unit also
supervises for no and low battery conditions.
Battery Cutoff
In order to protect the batteries when AC fails, the
battery voltage is constantly monitored, and if it
drops below 20.4V, all PAD-4 power will be cut
off. Power will be restored when AC is restored.
Ground Fault Detection
The PAD-4 monitors for ground faults to the
output wiring. When detected, the unit lights the
yellow GRND LED (DS6) and de-energizes the
trouble relay and the input supervision relays. In
addition, in ULC configuration, the ground fault
relay on the PAD-4-CLSA module is also energized. Ground fault indication is common to all
output circuits and all NAC outputs are to be in
the same evacuation zone.
Environmental
All hardware is suitable for use only in an indoor,
dry environment.
Power Limiting
The AC power and battery wiring are not power
limited. All other circuits leaving the control unit
are power limited.
Transient Protection
Transient protection devices are provided where
needed to meet the requirements of UL864.
1.2 REGULATORY STANDARDS
The PAD-4 meets the requirements of industry
and government regulatory agencies as noted.
Federal Communications Commission
The PAD-4 meets the Class A requirements of
the Code of Federal Regulations (CFR 47), Part
15, subpart B, for electromagnetic field emissions.

2.6.2.1 Multiple Module Battery Connection
For applications where multiple PAD-4 boards are
mounted in an enclosure with System 3 rails, it
may be possible to connect two boards to a
single battery set. When using a single battery set
for two boards, the following rules must be
followed:
a) Both PAD-4 boards must be located within
the same enclosure and mounted adjacent to
each other.
b) The combined battery A.H. rating required for
both boards does not exceed 18 A.H.
c) Each PAD-4 and associated FP2011-U1
must be mounted on S3AP adapters. Refer to
the S3AP manual, P/N 315-050257.
d) One of the PAD-4 boards must have its
charging circuit disabled.
e) Two (2) battery connection splitters (part
number 230-299203) are used on the battery
set for proper connection.
The following steps and diagrams explain how to
connect two PAD-4 boards to a single battery set.

methods for proper supervision. Note: MIN: 22 AWG, MAX: 12 AWG.
Class A (Style Z) Output Notification Circuits
The configuration shown in Figure 2-13 shows two, 3-amp devices wired as Class A (Style Z) circuits.
When you are using the outputs as Class A (Style Z) circuits, loop the wiring back to the corresponding
circuit pair. For Class A (Style Z) wiring, no external EOL is necessary since it is built into the board.
PAD-4-CLSA Module
The PAD-4-CLSA module provides connectivity to two circuits wired as Class A (Style Z). Refer to the
PAD-4-CLSA Installation Instructions, P/N 315-050254, for more information.
Class A (Style Z) Supervised Input Circuits
The configuration shown in Figure 2-13 shows Class A (Style Z) supervised wiring from a fire alarm
control unit to the PAD-4 board. Pay close attention to the polarities when wiring the unit and follow
these requirements:
When wiring to terminal 1-, you must use two separate wires. Do not loop a single wire or twist two
conductor wires together.
Do not use notification appliances on Class A (Style Z) circuits connected for input. The PAD-4 will
detect voltage across the input circuits, but is not designed to pass the added current load from notification appliances.

2.6.6 Common Trouble Relay
The PAD-4 board has a Form C trouble relay. The relay will de-energize under a trouble condition.
A typical application of the trouble relay is to connect the PAD-4 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. This will cause
a trouble on the fire alarm control unit when the PAD-4 opens its trouble contacts.
For AC Fail reporting, refer to Section 5.1.4 for configuration and response times.
Note: The N.C. contact is the relay contact that is closed when the PAD-4 has power and there are no
trouble conditions.

the protected premises.
2. For Canadian Installations: Program HTRI-S #1 as Trouble
causing, which will cause the DACT to signal and will also cause a
local visual and audible signal at the protected premises. Program
the DACT to send a Primary Power Failure signal to the receiving
unit when this HTRI-S is active.

2. 7 Ground Fault Detection Enable/
Disable
For some applications (when used with RSASeries annunciators, for instance), the PAD-4 is
used to provide power to an auxiliary device
which gets a control signal from a fire alarm
panel. The ground fault reference for the PAD-4
may be different than the reference used by the
fire alarm panel, resulting in a ground fault trouble
2.8 Input Emulation
The input circuits are normally driven by the fire
alarm control unit notification appliance circuit and
thus the PAD-4 will monitor the polarity of the voltage
coming from the fire alarm control unit to determine
when to operate the output NACs. Alternatively, the
input circuits can be driven simply by a switch, such
as a relay. If a switch operates the NACs, then it
must be wired in a metallic conduit within 20 ft
from the PAD-4 and in the same room.
Jumpers J11 and J12 configure which mode is
active for input 1 and jumpers J13 and J14
configure which mode is active for input 2. If
jumpers are connected to pins 1 and 2, then a
PAD-4 Installation, Operation and Maintenance Manual
at the panel even when none exists. To remedy
this condition, the PAD-4 can have its ground
fault detection circuit disabled. Once disabled, the
fire alarm panel’s ground fault detection circuitry
will detect any ground fault in the system. See
Section 5-2 for correct positioning of this jumper,
and see Figure 2-5 for the location of this jumper.
switch will activate the inputs. If jumpers are
connected to pins 2 and 3, then inputs are normally driven by fire alarm control unit notification
appliance circuits. See Section 5-2 for correct
positioning of this jumper, and see Figure 2-5 for
the location of this jumper.
If the PAD-4 is configured to monitor a switch,
such as a relay, then the fire alarm control unit will
not be able to receive trouble conditions through
its notification appliance circuit connected to the
PAD-4 input circuits. Use the PAD-4 trouble relay
when it is necessary to monitor trouble conditions.
Refer to Figure 3-8.

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.
The circuit shown in Figure 4-8 will provide up to 3 amps of door holder current. The power in this
example is released when AC power is off for 30 seconds or more, or when the relay from the fire alarm
control unit opens. See Section 1.1 for a description of the auxiliary power options, and Section 5.1.2 for
information on choosing the options.
NOTE: Compatible Door Holder: Rixson FM998. Approved for UL/ULC Installations.
RSG DH24120. Approved for UL/ULC/FM Installations.

5. PROGRAMMING
The PAD-4 functions are programmed with a 10position DIP switch and ten 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 in UL installations. Loss of AC
settings are disabled in Canadian installations
and AC Fail will be reported immediately.
• Which input (Input 1 or Input 2) will control
the NAC outputs

8. TROUBLESHOOTING
This section describes the LED states and provides possible trouble conditions of the PAD-4.
8.1 LED INDICATORS
Light-emitting diodes (LEDs) indicate fault and normal conditions. The seven LEDs indicate a fault
condition in one of the circuits (either outputs 1 through 4, auxiliary power, ground fault, or battery). A
fault condition in the LEDs corresponding circuit will turn on the LED (labeled on the board). The
POWER LED will normally be on and turn off to indicate an AC Fail condition. See Figure 2-5 for locations of LEDs. Their functions are as follows:
