WARNING Please Read Carefully

Note to Installers

This warning contains vital information. As the only individual in contact with system users, it is your responsibility to bring each item in this warning to the attention of the users of this system.

System Failures

This system has been carefully designed to be as effective as possible. There are circumstances, however, involving fire, burglary, or other types of emergencies where it may not provide protection. Any alarm system of any type may be compromised deliberately or may fail to operate as expected for a variety of reasons. Some but not all of these reasons may be:

■ Inadequate Installation

A security system must be installed properly in order to provide adequate protection. Every installation should be evaluated by a security professional to ensure that all access points and areas are covered. Locks and latches on windows and doors must be secure and operate as intended. Windows, doors, walls, ceilings and other building materials must be of sufficient strength and construction to provide the level of protection expected. A reevaluation must be done during and after any construction activity. An evaluation by the fire and/or police department is highly recommended if this service is available.

■ Criminal Knowledge

This system contains security features which were known to be effective at the time of manufacture. It is possible for persons with criminal intent to develop techniques which reduce the effectiveness of these features. It is important that a security system be reviewed periodically to ensure that its features remain effective and that it be updated or replaced if it is found that it does not provide the protection expected.

■ Access by Intruders

Intruders may enter through an unprotected access point, circumvent a sensing device, evade detection by moving through an area of insufficient coverage, disconnect a warning device, or interfere with or prevent the proper operation of the system.

■ Power Failure

Control units, intrusion detectors, smoke detectors and many other security devices require an adequate power supply for proper operation. If a device operates from batteries, it is possible for the batteries to fail. Even if the batteries have not failed, they must be charged, in good condition and installed correctly. If a device operates only by AC power, any interruption, however brief, will render that device inoperative while it does not have power. Power interruptions of any length are often accompanied by voltage fluctua- tions which may damage electronic equipment such as a security system. After a power interruption has occurred, immediately conduct a complete system test to ensure that the system operates as intended.

■ Failure of Replaceable Batteries

This system’s wireless transmitters have been designed to provide several years of battery life under nor- mal conditions. The expected battery life is a function of the device environment, usage and type. Ambient conditions such as high humidity, high or low temperatures, or large temperature fluctuations may reduce the expected battery life. While each transmitting device has a low battery monitor which identifies when the batteries need to be replaced, this monitor may fail to operate as expected. Regular testing and mainte- nance will keep the system in good operating condition.

■ Compromise of Radio Frequency (Wireless) Devices

Signals may not reach the receiver under all circumstances which could include metal objects placed on or near the radio path or deliberate jamming or other inadvertent radio signal interference.

■ System Users

A user may not be able to operate a panic or emergency switch possibly due to permanent or temporary physical disability, inability to reach the device in time, or unfamiliarity with the correct operation. It is important that all system users be trained in the correct operation of the alarm system and that they know how to respond when the system indicates an alarm.

■ Smoke Detectors

Smoke detectors that are a part of this system may not properly alert occupants of a fire for a number of reasons, some of which follow. The smoke detectors may have been improperly installed or positioned. Smoke may not be able to reach the smoke detectors, such as when the fire is in a chimney, walls or roofs, or on the other side of closed doors. Smoke detectors may not detect smoke from fires on another level of the residence or building. Every fire is different in the amount of smoke produced and the rate of burning. Smoke detectors cannot sense all types of fires equally well. Smoke detectors may not provide timely warning of fires caused by carelessness or safety hazards such as smoking in bed, violent explosions, escaping gas, improper storage of flammable materials, overloaded electrical circuits, children playing with matches or arson. Even if the smoke detector operates as intended, there may be circumstances when there is insufficient warning to allow all occupants to escape in time to avoid injury or death.

■ Motion Detectors

Motion detectors can only detect motion within the designated areas as shown in their respective installation instructions. They cannot discriminate between intruders and intended occupants. Motion detectors do not provide volumetric area protection. They have multiple beams of detection and motion can only be detected in unobstructed areas covered by these beams. They cannot detect motion which occurs behind walls, ceilings, floor, closed doors, glass partitions, glass doors or windows. Any type of tampering whether intentional or unintentional such as masking, painting, or spraying of any material on the lenses, mirrors, windows or any other part of the detection system will impair its proper operation.

Passive infrared motion detectors operate by sensing changes in temperature. However their effectiveness can be reduced when the ambient temperature rises near or above body temperature or if there are intentional or unintentional sources of heat in or near the detection area. Some of these heat sources could be heaters, radiators, stoves, barbeques, fireplaces, sunlight, steam vents, lighting and so on.

■ Warning Devices

Warning devices such as sirens, bells, horns, or strobes may not warn people or waken someone sleeping if there is an intervening wall or door. If warning devices are located on a different level of the residence or premise, then it is less likely that the occupants will be alerted or awakened. Audible warning devices may be interfered with by other noise sources such as stereos, radios, televisions, air conditioners or other appliances, or passing traffic. Audible warning devices, however loud, may not be heard by a hearing-impaired person.

■ Telephone Lines

If telephone lines are used to transmit alarms, they may be out of service or busy for certain periods of time. Also an intruder may cut the telephone line or defeat its operation by more sophisticated means which may be difficult to detect.

■ Insufficient Time

There may be circumstances when the system will operate as intended, yet the occupants will not be protected from the emergency due to their inability to respond to the warnings in a timely manner. If the system is monitored, the response may not occur in time to protect the occupants or their belongings.

■ Component Failure

Although every effort has been made to make this system as reliable as possible, the system may fail to function as intended due to the failure of a component.

■ Inadequate Testing

Most problems that would prevent an alarm system from operating as intended can be found by regular testing and maintenance. The complete system should be tested weekly and immediately after a break-in, an attempted break-in, a fire, a storm, an earthquake, an accident, or any kind of construction activity inside

or outside the premises. The testing should include all sensing devices, keypads, consoles, alarm indicating devices and any other operational devices that are part of the system.

■ Security and Insurance

Regardless of its capabilities, an alarm system is not a substitute for property or life insurance. An alarm system also is not a substitute for property owners, renters, or other occupants to act prudently to prevent or minimize the harmful effects of an emergency situation.

2.9 Connecting the Combus

The Combus is used by the Maxsys control panel and the modules to communicate with each other. The four Combus terminals of the main panel must be connected to the four Combus terminals or wires of all modules.

When wiring the Combus, the following conditions apply:

• Combus should be run in minimum 22 gauge quad (0.5mm), two pair twist preferred

• the PC4850 units can be homerun, connected in series or can be T-tapped

• each PC4850 unit should not be more than 1,000'/305m (in wire length) from the panel

• shielded wire is not necessary unless wires are run in an area that may present excessive RF noise or interference.

• cables greater than 2m in length must be rated VW1, FT1 or better.

Example of Combus Wiring PC4850 (B) is wired correctly as it is

within 1,000'/305m of the PC4020 (A), in wire distance

PC4850 (C) is NOT wired correctly as it is further than 1,000'/305m from the PC4020 (A), in wire distance. See your PC4020 Installation Manual for complete Combus wiring instructions.

2.10 Connecting More Than One PC4850

You can connect up to 16 PC4850 modules to one PC4020 system. All modules are connected to the same incoming telephone line. As well as connecting each module to the main panel through the Combus, you must also connect the modules to each other through the MUBL terminal, as shown.

Section 3: Programming the PC4850

This section describes how the PC4850 modules works, and how to program it. You can program the PC4850 using either of these methods:

• using a Maxsys system keypad

• using DLS-3 and a computer (see section 3.3, “Programming From DLS-3”, and the DLS-3 manual).

3.1 How the PC4850 Works

When the PC4850 is set up and running correctly, visitors will be able to call the tenant they want to talk to and the tenant will be able to open the door for them. Tenants will also be able to enter the building using their access code.

To Call a Tenant

When the PC4850 is not in use, the display will switch between the initial greeting message and the following message every few seconds:

To Find Tenant’s Name, Press #

Visitors who know the tenant code for the person they want to call can enter the code at any time. If no tenant code is programmed, or if the visitors don’t know the code, they can press [#] to find the name of the tenant they want to call. When scrolling through tenant names, the display shows (for example):

Jane Smith [*]Prev. [#] Next

The visitor may also press the number key correspond- ing to the first letter of the tenant names. This will dis- play the first name in the list beginning with that letter. For example, the [4] is associated with the letter “J”, “K”, and “L”. Pressing the [4] key will display the first name in the list beginning with “J”. Pressing [4] again will display the first name in the “K” list; pressing [4] again will display the first name in the “L” list. When you have arrived at the letter of the tenant’s name scroll to the tenant’s name as described above. If visitors find the correct name and press [0], or if they have entered a valid tenant code, the display changes to:

Calling Tenant, To stop push “#”

If the tenant’s telephone line is busy, the PC4850 will sound a 5-second busy tone and the display will show:

Line is Busy....

Please Try Again

The PC4850 will hang up the line if the tenant does not answer after the call time programmed by the installer.

If the tenant answers the telephone, he or she can talk to the visitor for the amount of time programmed by the installer (from 0 – 99 seconds). At the last ten seconds of talk time, the PC4850 will beep once and display a countdown of the last 10 seconds.

To Open the Door for a Visitor

• If tenants want to open the door for the visitor, they can dial [7] on their telephone. When they open the door, the speaker beeps once per second while the door is unlocked, and the PC4850 display shows:

3.2 Programming PC4850 From a Keypad

3.3 Programming From DLS-3

3.4 Enrolling the PC4850

Door Unlocked, Please Enter.

• If tenants want to open the alternate entrance (e.g., a second door, or car gate), they can dial [9] on the telephone (Touch-Tone telephones only).

To Enter the Building Using an Entry Access Code

If tenants want to enter the building using the entry access code they should:

1. Press [*] on the keypad.

2. Enter their access code. The PC4850 opens the door,

the speaker beeps once per second while the door is unlocked, and the PC4850 display shows:

Door Unlocked, Please Enter.

NOTE: When entering either the entry access code or the tenant code, the PC4850 allows a maximum of 3 seconds between key presses. If you wait longer than 3 seconds before pressing the next key, the PC4850 will go back to the greeting displays.

You can program the PC4850 right from a system keypad in the same way that you program other Maxsys modules. See your PC4020 Installation Manual for more information.

Record all your programming on the “Programming Worksheet” on page 10.

You can program the PC4850 from a remote computer using the DLS-3 software. To install and use the software, refer to the DLS-3 manual.

Once you have finished wiring the PC4850 module, you must enroll it on the PC4020 system. To enroll the module:

1. At a system keypad, enter Installer Programming by

pressing [*] [8] [Installer Code].

NOTE: The default Installer Code is [5555].

2. Scroll to “Module Hardware” and press the [*] key.

3. The message “Enroll Module” will appear. Press [*].

4. Scroll through the different modules until the module

you wish to enroll is displayed. Press the [*] key.

5. The keypad will display the message “Create Tamper

On Desired Unit.” Go to the PC4850 module to be enrolled and tamper it. Return to the original keypad. A message similar to the following will be displayed to confirm enrollment: “PC4850 TCS Mod 02 Enrolled”.

3.5 Programming Users’ Names, Telephone Numbers, and Codes

To get the PC4850 up and running, you, or the building staff, will need to program up to four items of information for each user:

• Access code (this is the same access code as for the rest

of the system)

• User name (the user name will be displayed on the

PC4850 LCD display so that visitors can find the user to call him or her)

• User telephone number, or line number for the No-Bill

option (so that the system can call the user when there is a visitor)

• Tenant code (optional - building staff can post a list of

tenant codes for visitors to enter on the keypad to call users)

For visitors to be able to call a user, you must program a telephone number, or telephone line number (if using the No Bill option) for each user name.

Make copies of the Tenant Information Record Sheet on page 11 to record user information.

To Program User Information:

1. At a system keypad, enter [*][5] followed by a [Mas-

ter Code].

2. The keypad displays:

Select (0) < > User No. Search

Press [0] or [*].

3. The keypad displays:

Sel. Code (0001) < > User 1

User 1 (Access Code 0001) is the System Master Code. Use the right arrow (>) key to scroll to the user you wish to program (for example, User 2). Press [*] to select the user.

4. The keypad displays:

Select (0) < > Program Code

This is the Program Code menu. Use the right arrow (>) key to scroll though each display in the Program Code menu. To select any menu item for programming, press [*].

Program Code

If users will enter an access code to enter the building or to use security system functions, program the 4- or 6digit access code for each user here.

1. When the keypad displays: “Select (0) Program

Code.” press [0] or [*].

2. The display will indicate “Enter Digits” followed by

“AAAA.” This is the default setting for the access code. Enter four or six digits for the new code.

3. Press [#]. The display will return to “Select (0) Pro-

gram Code.” The new code has been programmed.

NOTE: Do not program access codes that can be easily guessed and will compromise the security of your system (e.g., 1111 or 1234).

Edit User Name

You must program a user name for each access code. To program the user name:

1. From the Program Code menu, use the right arrow (>) key to scroll to the following display:

Select (2) < > Edit User Name

2. Press [2] or [*].

3. The display will read “Program Name.” For access code 0002, the default name will be “User 2.” Enter the new user name using the number keys in the following manner: The letters of the alphabet have been divided up among the 1 to 9 number keys on the keypad as follows: [1] = A, B, C, 1 [2] = D, E, F, 2 [3] = G, H, I, 3

[4] = J, K, L, 4 [5] = M, N, O, 5 [6] = P, Q, R, 6 [7] = S, T, U, 7 [8] = V, W, X, 8 [9] = Y, Z, 9, 0 [0] = Space For example, if you press the [4] key once, the letter

“J” will appear above the cursor on the display. Press the [4] key again, the next letter “K” will appear, and so on. If a different number key is pressed, the cursor will automatically move to the right one space. To erase a character, use the [<] [>] keys to move the cursor under the character, then press the [0] key.

NOTE: If a user does not want their name listed on the PC4850 display, but does want to have an access code, you can put a “!” at the beginning of the user name. To enter a “!”, press [*], then scroll to the message “ASCII Entry”. Press [*], then enter [033*].

4. Once the new name has been entered, press [#]. The display will return to “Select (2) Edit User Name.”

Access Code Label Options

There are other options available when programming labels. When programming the label, press the [*] key for the options menu. Use the arrow (< >) keys to scroll through each option. Press the [*] key to select. The available options are:

• Clear Display: Selecting this option will clear the

entire code label.

• Clear to End: This will clear the display from the char-

acter where the cursor was located to the end of the display.

• Change Case: This will toggle the letter entry between

uppercase and lowercase letters.

• ASCII Entry: This is for entering uncommon charac-

ters. Use the arrow (< >) keys to scroll through the available characters. Each character will be displayed along with the corresponding 3-digit ASCII number. If you know the character’s 3-digit number, enter it. Press the [*] key to enter the character into the code label.

User Telephone or Telephone Line Number

Program the telephone number for each user. If you are using the No Bill option, program the 3-digit telephone line number provided by your telephone company instead.

1. From the Program Code menu, use the right arrow (>) key to scroll to the following display:

Select (5) < > Phone Number

2. Press [5] or [*].

3. Enter up to 12 digits for the telephone number. If you are using the No Bill option, program the 3-digit telephone line number provided by your telephone company instead. If you need to program special characters into the telephone number, you can do this using hexadecimal digits. The following hexadecimal digits will insert special characters into the telephone number:

NOTE: In the No Bill Option, programming of Hexadecimal digits is not allowed. Hexadecimal digits will cause incorrect operation.

Special characters can be added to the telephone number in order to perform designated functions. Press the [*] key to enter the telephone entry options menu. The five options are as follows:

[0] Save: This can be selected for the telephone num-

ber to be stored in the panel’s memory, or simply press [#] when finished entering the telephone number.

[1] Dial tone search: This character will force the

panel to search for a dial tone at that point in the telephone number. A “D” on the display repre- sents a dial tone search. A dial tone search is already programmed as the first digit for each tele- phone number.

[2] Pause 2 Seconds: This will add a 2-second pause to

the dialing sequence, represented by the letter “A” on the display.

[3] Pause 4 Seconds: This will add a 4-second pause to

the dialing sequence, represented by the letter “E” on the display.

[4] DTMF [*]: This will add an asterisk to the tele-

phone number, represented by a “B” on the dis- play. The dialer will output the same frequencies as the Touch-Tone [*] key. This character is frequently required to disable call waiting.

[5] DTMF [#]: This will add a “#” to the telephone

number, represented by the letter “C” on the display. The dialer will output the same frequencies as the Touch Tone [#] key. In some instances, this character is used to disable call waiting.

4. When you are finished, press [#].

Tenant Code (Optional)

You can give visitors the option of entering a 4-digit code on the keypad to call a user. To do this, enter the 4-digit code for the apartment. If a user knows a visitor is coming, they can give them the tenant code as a faster way to call them.

1. From the Program Code menu, use the right arrow (>) key to scroll to the following display:

Select (6) < > Tenant Code

2. Press [6] or [*].

3. Enter up to 4 digits for the tenant code.

4. When you are finished, press [#].

Duplicate Entries

If the Duplicate Code toggle option is turned on in the PC4020 programming, you will not be able to program duplicate access codes. See your PC4020 Installa tion Man- ual for more information.

NOTE: We recommend that users who have different telephone numbers be given different tenant codes. If you program more than one user with the same tenant code, the PC4850 will only call the user who is first in alphanumeric order. Visitors will not be able to call any other user using that code. You can program users with the same name. However, if users have exactly the same name, visitors will not be able to distinguish between them when scrolling through the list of names.

NOTE: Cell phones shall not be programmed to allow access.

Section 4: Testing and Troubleshooting

4.1 Testing the PC4850

Once the PC4850 is connected and programmed, test each of its functions to make sure it is working correctly. The PC4850 should work as described in section 3.1, “How the PC4850 Works”.

4.2 Troubleshooting

The PC4850 should work correctly without the need for adjustments. However, if you encounter problems getting the unit to work, you can try adjusting the following controls on the PC4850 circuit board. To adjust these controls, first, remove power from the PC4850 (AC and battery power), then use a small screwdriver to change the appropriate setting.

LCD Contrast

If the LCD is hard to read, turn the control marked RV1 clockwise to increase the display contrast. To decrease the display contrast, turn the control counter-clockwise.

“Beep” Volume

The PC4850 keypad beeps whenever a key is pressed. You can adjust the volume of these beeps. To increase the volume, turn the control marked RV2 clockwise. To decrease the volume, turn the control counter-clockwise.

Microphone Volume

If users cannot hear visitors when they call using the PC4850, turn the control marked RV3 clockwise to increase the microphone sensitivity. To decrease the microphone sensitivity, turn the control counter-clock- wise.

Pulse Dial Sensitivity

If the PC4850 does not unlock the door when a user dials 9 using a pulse dial telephone, turn the control marked RV4 clockwise or counter-clockwise 1/10 of a revolution, until the door unlocks when 9 is dialed.

Speaker Volume

If visitors cannot hear the user they are calling on the PC4850, turn the control marked RV5 clockwise to increase the speaker sensitivity. To decrease the speaker sensitivity, turn the control counter-clockwise.

4.3 “System is Busy. Please Wait” Message

Whenever the system displays this message, visitors will not be able to call users using the PC4850, but users will still be able to enter the building using their access codes. Postal workers will also be able to enter if a postal lock has been installed.

If this message is displayed, check for a Telephone Line Trouble. This trouble will occur when the outgoing telephone line is disconnected from one or more units, or if the telephone line is out of service. When the telephone line is restored, the PC4850 will work normally. This message is also displayed when another PC4850 current has the line.
