SECTION 1
SYSTEM OVERVIEW
INTRODUCTION
The Simplex 4020 is a microprocessor-based Fire Alarm System.
It is UL-listed, power-limited, electrically-
supervised, and protected against loss of primary AC power and brown-out conditions.
The standard 4020 can control up to 127 MAPNET II@ points. Depending on options, the 4020 can control a
maximum of 254 addressable points. Since all points in a system may not be addressable, the 4020 also offers up
to 20 hardwired points (with 4 points standard) that can be used to interface with detector zones, bell or horn circuits,
and auxiliary relay control. Each hardwired point is individually configurable as either a monitor point, a signal circuit,
or as an auxiliary relay output, with up to 8 different points on a single card.
The 4020 offers a variety of ways to provide remote annunciation. It can communicate with the LCD annunciator,
the SCWRCU, or the graphic SCWRCU. The RS-232 interface can be used to output to a printer or CRT.
An alphanumeric display on the 4020 Operator Interface Panel (Figure 1) indicates the condition of the system. The
alphanumeric display shows various prompts and labels which guide the user through a sequenced operation for
each abnormal condition. Audible and visual indications are provided to indicate abnormal conditions when they
exist within the system.
The 4020 capacities are as follows:
l
Up to two MAPNET II@ channels with up to 127 addressable devices each for a total of 254 addressable
devices
l
Up to 20 hardwired points, configurable as monitor, signal, or auxiliary relay points
l
An RS-232 interface
l
Up to 31 remote annunciator locations, which can accommodate SCWRCU, graphic SCU/RCU, and LCD
annunciators
l
An 8-Amp switching power supply, with a battery charger capable of charging batteries with up to 50 Ah
capacity.
The default hardware for a 4020 includes a master controller with a display, master trouble points, city circuit, and
tone-alert. The standard slave module uses three card addresses. “Card (address) 1 W functions like an 8-point multi-
function I/O card, but only the first 4 points are available. “Card 2” is the power supply card. “Card 3” is the built-in
MAPNET@ channel.
The following optional hardware is allowed:
l
An additional MAPNET II@ card
l
Two eight-point multifunctional I/O cards
l
An RS-232 interface card configured with two isolated ports, with the ability for one port to be dedicated to
communications with a 2120 Multiplex System.
l
Serial annunciators including the LCD display, the SCWRCU, or the graphic SCWRCU
l
4120 Network Interface
l
25.5 Volt Limiter Module for Agent Release.
NOTE: This document covers operating procedures for a typical 4020 system. Applications will vary due to optional
hardware installed, custom programming, and local code requirements.

SYSTEM OPERATING DESCRIPTION
The 4020 Operator Interface Panel, hereinafter called the interface panel, shows the following under normal
conditions:
l
Green “POWER ON” LED ON (indicating that AC power is applied)
l
All other interface panel indications OFF
l
Alphanumeric LCD display states that the system is normal, as shown below.
SYSTEM IS NORMAL
08:23:43
MON 04-APR-94
I
I
Abnormal conditions are indicated on the interface panel by flashing the alarm, supervisory, or trouble LED and
sounding the tone-alert. The alphanumeric display provides information as to the point status (alarm, supervisory,
and trouble), type of alarm (smoke detector, pull station etc.), number of abnormal conditions in the system, and a
custom label. Alarm, supervisory, and trouble conditions each have their respective acknowledge key. Pressing the
appropriate acknowledge key will silence the tone-alert. However, the LED indicating the abnormal condition
remains illuminated until all initiating devices are restored to normal.
Figure 1
Interface Panel
(Access Door Closed)
If your system is configured with the CRT or printer option, point status is also displayed on these devices. The CRT
option controls various system functions. It can acknowledge system status changes, silence alarm signals, and
perform system reset procedures.
When an initiating device (monitor point) senses a Fire Alarm Condition (heat, smoke, manual activation, etc.),
notification appliances (signals) and the tone-alert sounds, and the FIRE ALARM LED turns ON and flashes,
indicating that a Fire Alarm condition is present. In addition, depending on the nature of the alarm condition, relays
trip, the city circuit activates, and various programmed events occur. The tone-alert continues sounding until the
alarm is acknowledged.
2
Technical Manuals Online! - http://www.tech-man.com
www.BevanSecurity.Com
When an initiating device senses a System Supervisory Condition (tamper valve off normal, generator status, etc.),
programmed notification appliances and the tone-alert sounds, the SYSTEM SUPERVISORY LED on the interface
panel turns ON and flashes, the city circuit may be activated (if required by local codes), and various programmed
events occur. The tone-alert continues sounding until the condition is acknowledged or cleared.
When the 4020 senses a malfunction within the system (loss of power, hardware failure, etc.), a Trouble Condition
is announced by the interface panel. The tone-alert sounds steady, the SYSTEM TROUBLE LED flashes and
various programmed events occur. The tone-alert continues sounding until the condition is acknowledged or
cleared.
NOTE: When an operator interface panel key is referenced within this manual, it is normally shown between left
and right arrows. Examples are cACK> and <ALARM SILENCE>.
All abnormal conditions must be acknowledged by pressing the cACK> key under the appropriate flashing LED.
Notification appliances are silenced by pressing the <ALARM SILENCE> key.
NOTE: When you press the <ALARM SILENCE> key, the ALARM SILENCED LED turns ON steady.
Depressing the <SYSTEM RESET> key restores the system to the normal operating mode if Fire Alarm Conditions
have been acknowledged and restored. Depressing the <PRIORITY 2 ALARM RESET> key on the CONTROL Key
Panel restores the system to normal operation if Priority 2 Alarm Conditions have been acknowledged and restored.
(All keys on the CONTROL Key Panel must be programmed for function.)
The tone-alert may be programmed to sound at specified time intervals to serve as a reminder that a trouble still
exists within the system (System Trouble Reminder).
The system has “re-sound” capability. If, after silencing the signals, the system detects another abnormal condition,
the zone with the abnormal condition is indicated on the interface panel alphanumeric display, the appropriate
indicator again flashes, and the signals again sound.
To provide maximum efficiency in performing primary fire alarm functions, an interface panel access door, shown in
Figure 1, covers all keys except those required for indication and interaction for emergency situations. (The access
door must be opened to reset Priority 2 Alarm Conditions.)
LOG IN PROCEDURE

HANDLING ABNORMAL CONDITIONS
When an abnormal condition occurs, at least one of the interface panel LEDs (FIRE ALARM, PRIORITY 2 ALARM,
SYSTEM SUPERVISORY, or SYSTEM TROUBLE) flashes, and the tone-alert sounds. The alphanumeric display
on the interface panel shows the total number of abnormal conditions present in the system. At a glance, you know
how serious the situation is by reading the number of abnormal conditions displayed, such as the single alarm
- condition shown below.
I
**FIRE**
Press <ACK> to review.
FIRE = 1 PR12 = 0 SUPV = 0
TRBL = 0
I
The system also creates a “List” when abnormal conditions exist. The list contains the number of abnormal
conditions present in the system. The cACK> keys are pushed to view the abnormal condition list, and review each
condition, if required.
When an Alarm Condition is detected by the system, the appropriate ALARM LED flashes and the tone-alert pulses.
For supervisory and trouble conditions, the appropriate interface panel LED flashes, and the tone-alert sounds
steady.
5
Technical Manuals Online! - http://www.tech-man.com
www.BevanSecurity.Com
Pressing the appropriate cACK> key (under the flashing LED) displays the first acknowledged condition in the
appropriate list. Note that the cACK> function may be passcode protected. If you have insufficient privilege to
acknowledge the condition, a message will indicate the problem, and will allow you to view the points without
acknowledging them. If you have sufficient privilege to acknowledge the condition, a message is displayed informing
you that the condition has been acknowledged. (See Operator Access Levels, Section 8, and Log In Procedure,
Section 1, for details.)
The 4020 system can be configured with either Global or Individual Acknowledge. When Global Acknowledge is
used in the system, one press of an <ACK> key globally acknowledges every abnormal point in the system in that
category. If all the points are acknowledged in this manner, an appropriate message is displayed. When Global
Acknowledge is used in a system, and the supervisory service or trouble conditions clears, the abnormal condition
automatically clears. Alarm conditions must be acknowledged. If Individual Acknowledge is used in the system, the
appropriate <ACK> key must be pressed for each condition change.
Note that the acknowledge function imposes a delay of at least one second between point acknowledgments. This
minimum delay allows you to view the information displayed on the alphanumeric display for each point that is being
acknowledged by the cACK> key.
When a point is acknowledged, the interface panel status LED glows steady, and the tone-alert silences. The total
number of alarm, supervisory, and trouble conditions show on the alphanumeric display along with a prompt to press
the cACK> key for point review. Pressing the cACK> key scrolls through the selected list in chronological order.
Each list is different and contains information concerning a particular abnormal condition.
After 30 seconds of keypad inactivity, the total number of abnormal conditions is again shown on the alphanumeric
display. Pressing the cACK> key selects a list for review. The first point to be displayed is either the first
acknowledged point in the list, or the first point in the list if all are acknowledged.
Alarm, supervisory, and trouble lists are displayed in chronological order. A message will indicate when the end of
a list has been reached.
The last message contains the total number of abnormal conditions, such as the single alarm message shown
below.
I
**FIRE**
Press <ACK> to review.
FIRE = 1 PRIZ = 0 SUPV = 0 TRBL = 0
The <DISPLAY TIME> Key
The <DISPLAY TIME> key is used to view the time of day when the abnormal condition occurred. By viewing the
time for each abnormal condition occurrence, fire department personnel can determine the path and possible cause
for each abnormal condition.
Note that the <DISPLAY TIME> key only displays time for existing abnormal conditions.
Using the <DISPLAY TIME* Key
The red <DISPLAY TIME> key works for any point currently in an alarm, supervisory, or trouble condition. The alarm
list information is obtained from the historical log and is shown on the alphanumeric display, in order of occurrence.
In situations where multiple conditions are present, you can simply push one key to review the time that each
abnormal condition occurred. An example of an alarm condition is shown below.

SECTION 2
ALARM CONDITIONS
INTRODUCTION
CAUTION
FOLLOW LOCAL OPERATING PROCEDURES WHEN INVESTIGATING ALARM CONDITIONS.
NOTE: Refer to Figure 2 for locations of interface panel LEDs and Keys.
When an Alarm Condition is detected by the 4020, the condition is indicated by the following:
l
Red “FIRE ALARM” or “PRIORITY 2 ALARM” LED is flashing
l
Tone-alert is pulsing
l
LEDs on annunciators may illuminate
l
The alphanumeric display on the interface panel indicates an alarm condition, such as the Fire Alarm condition
shown below.
I
**FIRE**
Press <ACK> to review.
FIRE = 1 PR12 = 0
SUPV = 0
TRBL = 0
I
The interface panel has two red LEDs which are used to indicate alarm conditions. When a Fire Alarm condition or
a Priority 2 Alarm Condition occurs, the appropriate red LED flashes, the tone-alert pulses, and an alarm message
appears on the alphanumeric display. When the appropriate <ALARM ACK> key is pressed, the red LED stops
flashing and glows steady, and the tone-alert silences. When the <ALARM SILENCE> key is pressed, the system
signals are silenced. When the appropriate <SYSTEM RESET> key is pressed, the alarm condition clears and the
red ALARM LED turns off.

HOW TO RESET THE SYSTEM
When the alarm condition has been cleared, restore or replace all affected devices (pull stations, smoke detectors
etc.) in accordance with the instructions provided with each device.
Since the system reset procedure for a Fire Alarm Condition differs from the system reset procedure for a Priority 2
Alarm Condition, the system reset procedure you use will depend on the nature of the alarm condition. Use one of
the following procedures to reset the system:
l
To reset a FIRE ALARM Condition: Press the <SYSTEM RESET> key.
l
To reset a PRIORITY 2 ALARM Condition: Open the interface panel door and press the <PRIORITY 2
ALARM RESET> key on the CONTROL panel. Then, after the ALARM LED flashes and the tone-alert pulses,
press the <ALARM ACK> key twice. (After a delay, the system returns to normal and the display reads:)

ESSENTIAL ALARM CONDITION KEYS
The essential keys for alarm conditions are the <ALARM ACK> (Alarm Acknowledge), <ALARM SILENCE>, and the
<SYSTEM RESET> keys. The remaining keys are concealed by the interface panel access door and are associated
with advanced system functions. (See Section 8, Advanced Functions.)
ALARM ACKNOWLEDGE KEYS
The <ALARM ACK> keys are located directly under the FIRE ALARM LED and the PRIORITY 2 ALARM LED.
Pressing the <ALARM ACK> key (twice for Individual Acknowledge or once for Global Acknowledge) causes the
ALARM LED to change from flashing to steady ON and silences the tone-alert. Pressing the <ALARM ACK> key
does the following:
l
Selects the next unacknowledged alarm point in the list for display (Individual Acknowledge)
l
Acknowledges the displayed point or acknowledges all points on the list (Global Acknowledge)
l
Scrolls the points chronologically after all points have been acknowledged.
If the <ALARM ACK> key is passcode protected, you cannot use this key to acknowledge alarms unless you have
the required access level. (See Operator Access Levels, Section 8, and Log In Procedure, Section 1.)
There are two types of acknowledges for the 4020 system: Global Acknowledge and Individual Acknowledge. Each
acknowledge type operates with the System Alarm Condition in the following manner.
l
Global Acknowledge - When Global Acknowledge is used on the 4020 system, a single key press of the
<ALARM ACK> key acknowledges all alarm status changes in the system. If status change information is
required, you may review this data by pressing the <ALARM ACK> key and reading the alphanumeric display.
l
Individual Acknowledge (For NFPA 72 Proprietary Receiver Requirements) - If an alarm condition has
been acknowledged with the <ALARM ACK> key and further unacknowledged conditions remain in the
system, the tone-alert continues sounding and the next status change shows on the alphanumeric display.
This process repeats until all changes are acknowledged. When this occurs, the tone-alert silences, and the
highest priority acknowledge change appears on the display.
ALARM SILENCE KEY
CAUTION
PRESSING THE ALARM SILENCE KEY CAUSES FIRE ALARM EVACUATION SIGNALS TO TURN
OFF: FOLLOW LOCAL PROCEDURES TO SILENCE ALARM EVACUATION SIGNALS.
When an alarm condition exists, various signals, auxiliary relays, the city connection, and the tone-alert may activate
(depending on the type of alarm condition, the system configuration, and the stage of the alarm condition). The
<ALARM SILENCE> key, when pressed, turns OFF all circuits programmed to follow the Alarm Silence key. The
<ALARM SILENCE> key press will:
l
Turn OFF signal circuits
l
Turn ON the ALARM SILENCED LED
l
Display a message, such as the one shown below.
