SECTION 1: INTRODUCTION
This manual provides installation and operating procedures for the Westinghouse Security
Electronics (WSE) SE 3718S Uninterruptable Power Supply (part number 92371800000).
Included are specifications, operation description, controls and indicators, installation data, and
a troubleshooting guide.
NOTE
•
Changes or modifications to the equipment described herein not expressly approved by
Westinghouse Security Electronics can void the warranty and the authority of the user to
operate the system.
•
Repairs to the SE 3718S shall be limited to those that can be performed without removing
the unit from its case.
•
The information in this manual assumes that the reader is familiar with access control and
alarm monitoring technology, and standard installation practices.
•
The information in this manual is not intended to conflict with and/or supplement the building
codes, electrical codes, or safety codes to which any given installation must conform.
CONFIGURATION
The SE 3718S is available in one configuration which accommodates both 115 and 230 volt AC
power input. Lock voltage is switch-selectable between 12 and 24 volts. Backup battery power
is standardized at 24 volts nominal.
SYSTEM OVERVIEW
The SE 3718S is a true uninterruptable power supply in that it takes power from power lines or
external storage batteries (always online in case of power failure). Normally, when AC power is
available, the batteries are always kept charged. If a power failure occurs, the batteries take over
immediately until AC power is restored.
To accomplish this, the 3718S is actually two power supplies working together. The first, or
primary power supply, provides low voltage for battery charging, and for the secondary power
supply which, in turn, produces all system voltages. During power outages, the batteries continue
to provide the low voltage needed for the secondary power supply.
1-2
INTRODUCTION
SYSTEM APPLICATIONS
The SE 3718S provides sufficient power to run an access control system consisting of the
following components:
•
One 700- or 800-series ACU.
•
Up to eight multiple switch monitors (SE774, SE774A) or eight door switch monitors
(SE770).
•
Up to eight analog proximity sensors.
•
A 24-volt backup battery.
•
One SE 778 / 778A annunciator/control module powered by the ACU in 800-series systems.
•
One modem (or similar accessory).
•
Up to eight WSE provided RS-485 communication devices.
•
Several low-current locking devices or similar accessories (see below).
The SE 3718S runs on any voltage from 85 to 264 VAC (47-63 Hz), and drives systems with either
12- or 24-volt locks at the touch of a switch. To provide maximum energy efficiency, the battery
is nominally 24 volts.
At facilities without emergency power systems, the SE 3718S provides limited emergency power
to maintain access control. The total amount of power it can deliver is fixed and should not be
exceeded (fuses could blow). Therefore, any devices in addition to those listed above may cause
the 3718S to be damaged or operate incorrectly.
As noted, installation personnel should be careful to avoid overloading the system. Because of
the many lock types available and the dynamic nature of their power requirements, and also
because of the many system configurations available, it is impossible to state exactly the number
of locks the SE 3718S is capable of driving. However, for a typical system configuration
consisting of one ACU controlling several doors, the continuous lock power load should not
exceed 4 amps at 12 VDC or 2 amps at 24 VDC. Neither should the load capacitance exceed
10,000 uF or the power supply may fail to stay online. If additional lock power is required, some
or all lock power will probably need to come from an external power supply instead of the SE
3718S.
IMPORTANT
Any external power supply must function independently and must not be paralleled with the SE
3718S. Consequently, heavy lock power loads, monitoring modules such as motion detectors,
glass break detectors, infrared sensors, and smoke detectors should not be powered by the SE
3718S; they should have separate power supplies.

FUNCTIONAL DESCRIPTION
A functional block diagram of the SE 3718S Uninterruptable Power Module is shown in Figure
2-3. The SE 3718S circuitry consists of four main functional elements as described below.
Figure 2-3: SE 3718S Functional Block Diagram
PRIMARY SWITCHING POWER SUPPLY CIRCUITRY
The purpose of the primary switching power supply circuitry is to convert the input AC (85 to 264
VAC) to a DC level comparable to that provided by an optional backup battery. Normally, this
DC level (not directly available to the end-user) is used to drive the rest of the power supply. In
case of a power failure, this circuitry ceases to operate, and the optional backup battery (if it is
installed) takes over.
There are no user-serviceable parts or fuses associated with the primary switching power supply.
BATTERY CHARGER CIRCUITRY
The battery charger circuit has two basic functions. In normal operation, it takes power from the
primary switching power supply and provides a controlled charging current to the optional backup
battery. During power failures, the battery charger circuitry connects the battery to the rest of
the power supply.
To accomplish these functions, the battery charger is equipped with special circuitry to detect the
presence of a viable backup battery, and to monitor its charging state during normal operation.
In the event of a power failure, the circuit is also designed to protect the battery from overdischarging.
The battery fuse is a 10-amp, metric, slow-blow fuse (5X20 mm 10A T/SB).
2-4
DESCRIPTION
SECONDARY SWITCHING POWER SUPPLY
The secondary switching power supply converts and distributes power from either the primary
switching power supply or the backup battery to all output terminals of the 3718S.
CONTROL AND INDICATORS CIRCUITRY
The main function of the control and indicator circuitry is to sense and control the operation of
the rest of the power supply. Additionally, it reports on important power supply conditions either
by status indicators on the top panel or by sending signals directly to the ACU.
The conditions reported to the status indicators on the front panel include: The presence of AC
input power, whether a backup battery is connected, if that battery is fully charged, if ACU system
voltages are present and in range, and whether lock voltage is present and in range.
The conditions reported directly to the ACU include AC power failure (in case of short-term
outages) and impending battery failure (in case of long-term outages).
INDICATOR LEDS
As shown in Figure 2-2, five LEDs are mounted on the SE 3718S control panel. These LEDs are
controlled by the control and indicator circuitry and function as follows:
AC ON
Lights when unit connected to and operating from AC power
BATTERY CONNECTED
Lights to indicate presence of battery.
BATTERY FULL
Lights to indicate fully-charged battery. LED goes out when the
battery is no longer fully charged.
SYSTEM OK
Lights indicating all system voltages are present and within limits.
LOCK OK
Lights to indicate that lock voltage is available and within limits.
CONTROLS
CIRCUIT BREAKER
Turns power supply on and off.
12/24 LOCK VOLTAGE
Selects between 12V and 24V output at the lock terminals (J4)
GROUND ISOLATION
Used to connect/disconnect low-voltage ground from chassis.
NOTE
This feature does not disconnect the power supply chassis from third-wire grounding at the power
connector, but it does disconnect the low voltage common from the chassis ground and this can
be used to eliminate certain communications problems associated with ground loops.

LOCATION AND MOUNTING
IMPORTANT
The suitability of the use of flexible cord per CEC rule 4-010 is to be determined by the local
inspection authority having jurisdiction.
L'emploie d'un cordon souple selon l'article 4-010 de CCE première partie doit être soumis à
l'approbation des autorités locales d'inspection.
The length of the ACU power cable is 6 feet (1 M) and the SE 3718S position relative to the ACU
must be within this limit.
The SE 3718S can be located in the same cabinet as the ACU it is powering. However, the power
module should not be mounted below the ACU as the heat radiated by it can raise the ACU
temperature above the prescribed limit.
Airflow through the ventilation holes should be unrestricted. Ideally, the unit should be mounted
horizontally to allow air to flow upward through the unit.
If the cabinet temperature can rise to 120 o F (49o C), cut ventilation holes in both the top and
bottom of the enclosure. If this is insufficient, a cooling fan must be installed.
WIRING REQUIREMENTS
A dedicated AC branch circuit for the SE 3718S and the entire access control system must be
installed. Powering other equipment from the same circuit can induce tripped circuit breakers
and blown fuses (power failure).

BATTERY CABLE CONNECTIONS
The SE 3718S is designed to operate from a backup battery system of approximately 24V in the
event of a power failure. Unlike previous designs, the requirements of the battery backup system
do not depend on lock voltage settings and use either two 12-volt or a single 24-volt battery.
Connections between the SE 3718S and the various battery configurations using the battery
cable are shown below.
NOTE
Discharged batteries or batteries of the wrong type are not recognized and, internally, the SE
3718S automatically disconnects itself from them. Ensure that the batteries are fully charged
and are the correct type or equivalent (see Table 1-1).
