EXPOSURE TO RADIO FREQUENCY ENERGY

In 1991, the Institute of Electrical and Electronics Engineers (IEEE), and in 1992, the American National Standards Institute (ANSI), updated the 1982 ANSI Standard for safety levels with respect to human exposure to RF energy. Over 120 scientists, engineers and physicians from universities, government health agencies and industry, after reviewing the available body of research, developed this updated Standard. In March 1993, the U.S. Federal Communications Commission (FCC) proposed the adoption of this updated Standard.

The design of your Telular Telguard complies with this updated Standard. Of course, if you want to limit RF exposure even further than the updated ANSI Standard, you may choose to install the unit in a manner that locates its antenna at an even greater distance from the general public than is recommended as a minimum by the standard.

To insure compliance with the standard, when selecting a mounting location for your Telguard do not mount it (or its associated antenna) in an area where the general public could reasonably be within 8 inches (20 centimeters) of the antenna.

EFFICIENT OPERATION

Do not operate your Telular product when holding the antenna. Be sure to mount the unit such that its antenna is a minimum of eight (8) inches (20 centimeters) is maintained from the general public.

For the best service quality, keep the antenna free from obstructions and point the antenna straight up.

ANTENNA CARE AND REPLACEMENT

Do not use the unit with a damaged antenna. If a damaged antenna comes into contact with the skin, a minor burn may result. Have your antenna replaced by a qualified technician immediately. Use only a manufacturer-approved antenna. Non-approved antennas, modifications, or attachments could impair service quality, damage the Telguard and violate FCC regulations.

ELECTRONIC DEVICES

Most modern electronic equipment is shielded from RF energy. However, RF energy from cellular devices may affect inadequately shielded electronic equipment. RF energy may affect improperly installed or inadequately shielded electronic equipment operating in homes and businesses. Check with the manufacturer or its representative to determine if these systems are adequately shielded from external RF energy. Consult the manufacturer of any personal medical devices (such as pacemakers, hearing aids, etc.) to determine if they are adequately shielded from external RF energy.

BLASTING AREAS

To avoid interfering with blasting operations, turn OFF your unit when in a “blasting area” or in areas posted: “Turn off two-way radio.” Construction crews often use remote control RF devices to set off explosives.

POTENTIALLY EXPLOSIVE ATMOSPHERES

Turn OFF your unit when in any area with a potentially explosive atmosphere. It is rare, but your Telguard Digital or its accessories could generate sparks. Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death. Areas with a potentially explosive atmosphere are often, but not always, clearly marked. They include fueling areas such as gas stations; below deck on boats; fuel or chemical transfer or storage facilities; areas where the air contains chemicals or particles, such as grain, dust, or metal powders; and any other area where you would normally be advised to turn off your vehicle engine.

Do not transport or store flammable gas, liquid or explosives in the area of your Telguard Digital or accessories.

Vehicles using liquefied petroleum gas (such as propane or butane) must comply with the National Fire Protection Standard (FPA-58). For a copy of this standard, contact the National Fire Protection Association, One Batterymarch Park, Quincy, MA 02269, Attn: Publications Sales Division.

PART 68

This equipment complies with Part 68 of the FCC Rules. Located on the inside cover of the Telguard model TG4G0001 is a label that contains, among other information, the FCC Registration Number and Ringer Equivalence Number (REN) for this equipment. If requested, this information must be provided to the Telephone Company.

The Telguard - Cellular Alarm Transmission System is registered for connection to the public telephone network using an RJ38X or RJ31X jack. When selecting a mounting location, do not mount this unit in an area where the general public could reasonably be within 20cm (8 inches) of the antenna. The ringer equivalence number (REN) is used to determine the quantity of devices, which may be connected to the telephone line. Excessive REN's on the telephone line may result in the devices not ringing in response to an incoming call. In most, but not all areas, the sum of the REN's should not exceed five (5.0). To be certain of the number of devices that may be connected to the line, as determined by the total number of REN's, contact the telephone company to determine the maximum of REN for the calling area.

REPAIR AND WARRANY

If the Telguard Cellular Alarm Transmission System caused harm to the telephone network, the Telephone Company will notify you in advance that temporary discontinuance of the service may be required. But if advance notice is not practical, the Telephone Company will notify the customer as soon as possible. Also, you will be advised of your rights to file a complaint with the FCC if you believe it is necessary. The telephone company may make changes in it's facilities, equipment, operation, or procedures that could affect the operation of the equipment. If this happens, the Telephone Company will provide advance notice in order for you to make the necessary modifications in order to maintain

FUTURE TESTING AND LIMITATIONS ON USE

Telguard is part of an advanced design alarm-communication system. It does not offer guaranteed protection against burglary and fire. Any alarm communication system is subject to compromise or failure.

The Telguard is off for any reason, however briefly, and at the same time, the backup battery is missing, dead or not properly installed.

The cellular radio network, needed to transmit alarm signals from a protected premises to a central monitoring station, may be inoperable or temporarily out of service. Cellular radio networks are also subject to compromise by sophisticated methods of attack.

This equipment, like any other electrical device is subject to component failure. Although this equipment is designed to be long lasting, the electrical components could fail at any time.

Due to these limitations, we recommend that if the automatic self-test feature is not enabled, other arrangements be made with the user to test the system at least once every three months. Moreover, arrangements should also be made for on-site inspection/test by a licensed alarm installer at least once each year.

1.0 GENERAL DESCRIPTION AND OPERATION

The Telguard model TG-4 is a digital cellular radio alarm transmission device used to provide a back-up transmission path (cellular) for control communicators (C/Cs). When transmitting alarms it will attempt to use the secondary transmission path (Cellular) when the Primary path is not available. When transmitting an alarm signal, Telguard obtains its data from the C/C by way of a telco interface. The Telguard will obtain all alarm signal information including monitoring station phone number, account number and all zones for every alarm transmission. The Telguard transmits a Link Request to the Telular Communication Center and when a link acknowledgement is received, the Telguard handshakes with the C/C and causes the C/C to transmit the alarm data. Telguard encodes the alarm data into SMS (Short Messaging System) protocol and transmits to the local digital cellular network provider. The signal is routed from the network provider to the decoding Telular Communication Center. The Telular Communication Center performs a function similar to a central station receiver and issues the transmission acknowledgement when the last message in the transmission is received. After decoding and reformatting, the alarm signal is routed over the telco line (Public Switched Telephone Network - PSTN) to the appropriate alarm company central station for action.

In a typical alarm installation, Telguard is installed in the same area as the host alarm system. The incoming telco line is connected from the premises RJ-31x jack to Telguard and then from Telguard's RJ-45 jack to the host C/C digital dialer in the normal fashion. Two programmable supervisory trip (STC) outputs are available for connection to the host control/communicator's trip zone input terminals in order to provide a Telguard trouble signal to the C/C. Additionally, automatic self-test and status-on-demand report signals are transmitted exclusively over the cellular network to the Communication Center. Telguard has its own internal power supply/battery charger. All telco line and cellular monitoring, switching and supervisory functions are built in. No extra modules are required.

The Listed equipment at the Telular Communication Center (TCC) plays a key role in the operation of every Telguard. All Telguard units are required to use the Communication Center because of the C/C alarm signal format encoding and decoding requirements used in packet-data transmissions over the digital cellular network. The Communication Center also manages the real-time databases for cellular activation and a complete history of every Telguard's operating conditions. These conditions include programming setup information, cellular alarm transmission information, supervisory trouble information, status-on-demand information, and automatic self-test information.

2.0 FEATURES

This section summarizes the key features of the Telguard. Actual installation instructions begin in Section

5.0.

2.1 OPERATING MODE

The Telguard is a digital cellular SMS transmission device that is installed at the protected premises to provide alarm transmission integrity for security systems. It is used to provide a back-up transmission path (cellular) for control communicators (C/Cs). If the primary path is not available the C/C will attempt to transmit the alarm message over the cellular network.

2.1.1 Auto Format Detection

Telguard Digital default program setting is for Auto Detection of the C/C alarm format. Auto Format Detect feature allows the Telguard to adapt to receive any listed (see section 2.2) format on every alarm transmission. If the C/C alarm format is changed for whatever reason, the Telguard will sense the new format and accept the alarm signal. Note: Auto Format Detection does not support SIA2 or DMP formats. SIA2 and DMP must be programmed manually.

2.2 C/C COMMUNICATION FORMATS

The Telguard reads the C/C’s alarm messages and converts the C/C’s Ademco Contact ID, SIA2, 4x2 or 3x1 with 1400Hz or 2300Hz handshake data format into SMS packet data protocol for transmission over the cellular radio network. In order for the C/C to be compatible with the Telguard, the C/C must be programmed to transmit alarm messages to the central station using one of the following non-extended formats:

• Pulse Formats:

o 3+1 pulse; 10pps, Double Round, 1400Hz ack o 3+1 pulse; 20pps, Double Round, 2300Hz ack o 3+1 pulse; 40pps, Double Round, 2300Hz ack o 4+2 pulse; 20pps, Double Round, 1400Hz ack o 4+2 pulse; 20pps, Double Round, 2300Hz ack o 4+2 pulse; 40pps, Double Round, 2300Hz ack

• Ademco Contact ID

• Radionics Modem IIe or IIIa

• SIA2 (SIA-DC-03 level 2 release at 300 baud)

• DMP

Hexadecimal account numbers (001-FFF or 0001-FFFF) can be used with 3+1 or 4+2 formats, but Contact ID and Radionics requires a four digit account number using digits 0-9 (0001-9999).

2.3 COMPLETE SUPERVISION OF COMMUNICATION PATHS

The Telguard continuously supervises both the primary (telco) and the secondary (cellular) communication paths. If either path becomes inoperative, the Telguard generates a relay trip output that can be connected to a zone input of the host control communicator and/or used to activate remote sounding devices.

2.3.1 Line Fault Condition (LFC)

The Telguard monitors voltage on the incoming telco line. If an inoperative telco line is identified, (voltage below –20vdc, on hook) a telco line fault condition (LFC) is declared. The System Trouble Condition LED (STC LED) will flash 3 times and the STC relay will trip after a 30 or 60 second programmed delay. Upon telco restoral, the relay and STC LED are returned to normal.

2.3.2 No Service Condition (NSC)

Telguard declares a no service condition (NSC) when the measured “receive” cellular radio signal strength at the protected premises drops to -114 dBm or less. NSC is programmable to trip the supervisory relay output (STC2) after a 30 or 60 second delay. When STC trips, the STC LED will flash 4 times. Restoral of this condition occurs when a measurable signal strength greater than –114 dBm is maintained for the trip period of 30 or 60 seconds.

2.3.3 Radio Communications Failure Condition (RFC)

Radio communications failure condition (RFC) is declared when Telguard is unable to transmit over the cellular network even with acceptable signal strength. RFC is indicated by STC LED flashing 5 times.

2.4 COMPLETE POWER SUPERVISION

Telguard monitors its backup battery as well as its AC power source and reports power conditions from either. Telguard’s integrated control and power module incorporates a battery charging circuit. This battery charger circuit is also monitored.

2.4.1 Low/Missing Battery Condition (LBC)

The Telguard checks the backup battery voltage on initial power-up and every 60 seconds thereafter. If the battery voltage changes from ‘good’ to ‘bad’ state and is less than 11.6 volts, a LBC is declared whereby the STC LED blinks twice (every 5 seconds) and the STC relay trips. When the battery voltage increases to 12.1 volts, the STC LED and STC relay restore. Telguard also indicates Low/missing Battery Condition (LBC) when battery charger fails.
