Telonics trapsite transmitters can be used to monitor and report status of various traps including box traps, culvert traps, clover traps, leg-hold traps, and corral traps. These transmitters provide one signal or message when the trap has not been triggered, and the signal or message changes when the trap is triggered. This allows the user to know the status of a trap without actually visiting and possibly disturbing the trap site. Since there is less disturbance of the trap site, trapping success can be improved. The ability to know remotely when a trap is triggered also facilitates animals being removed from traps in a timely manner.
Telonics currently produces two general types of trapsite transmitters:
VHF configurations are used for monitoring from the ground or aircraft. They change pulse rate when triggered (e.g. from 50 to 100 beats per minute).
Satellite-linked transmitters operate through the Globalstar satellite system to provide automated remote monitoring. When a trap is triggered it immediately transmits through Globalstar, and a “triggered” email message is sent.
Trapsite transmitters are equipped with a lanyard containing a magnet on one end. The lanyard is attached to a portion of the trap that moves when triggered, such that triggering the trap separates the magnet from the trapsite transmitter and activation of the "triggered" mode.
VHF Trapsite Transmitters
Telonics VHF trapsite transmitters' standard operation includes two user-specified pulse rates: a "standby" pulse rate indicates that the unit is operational, but not triggered, and a second pulse rate indicates that the unit has been triggered.
Date and time of the most recent 9-16 changes from active to un-triggered to triggered or back are stored on board the transmitter, and that data can be recovered using Telonics Product Programmer (TPP) and physically connecting to the transmitter. In this way, if the user can recover the specific time that the trap was triggered.
VHF transmitters can alternatively be provided with a variable pulse rate that is related to the time since the triggering event (this is described in more depth below).
VHF units are monitored using a conventional VHF receiver and antenna, normally from the ground but potentially via aircraft.
Designed primarily for monitoring leg hold traps. Whip antenna.
Note: Lifetime estimates are based on continuous operation at 1200ms pulse period (50 beats per minute) at 0°C. Operational temperature range is 70°C to -40°C for the TBT-503-3, TBT-504-3, and TBT-550-3 (lithium batteries), and 55°C to -20°C for the TBTR-100-1 (alkaline batteries).
Globalstar Trapsite Transmitters
The TBT-4560-4 and TBTR-4360-4 transmitters operate through the Globalstar satellite system, which provides coverage in almost all terrestrial areas of the world. (There are gaps in coverage in central Africa, extreme polar regions, and in many oceanic areas.) An activation fee of approximately $30 per transmitter and monthly fees of approximately $5 per transmitter apply for use of the Globalstar system.
The TBT-4560-4 is a lithium primary battery system. The TBTR-4360-4 operates off a user-supplied CR123 or DL2/3A (3V, lithium) battery. When a trap is triggered, a Globalstar transmission is immediately triggered and that results in an email to the address assigned to that particular TBT-4560-4. That way you can receive immediate notification when a trap is triggered as long as you are able to receive email. If the status of the trap has changed since the prior day (e.g. it has been initially activated, or a daily "check-in" transmission is missed), that information is also sent to the registered email address. These units include a VHF transmitter, which can operate according to user-specified timing and pulse rates, and which changes pulse rates when triggered as with a VHF trapsite transmitter.
In addition to email notification of trap-trigger and other changes in status of a trapsite transmitter, you can obtain the most recently transmitted status of your Globalstar trapsite transmitters via Telonics-provided username and password access using the following link: Check Your Telonics Globalstar Trapsite Transmitter Status
Note: The lifetime estimates are based on a daily Globalstar transmission, the VHF transmitter operating at 2000ms (30 beats per minute) for 8 hours per day, and extended operation at 0°C. For the TBTR-4360-4, operational life assumes one DL 2/3A lithium cell is installed; a second cell can be installed to double operational life. Overall operational temperature range is 70°C to -40°C for the TBT-4560-4, and 70°C to -20°C for the TBTR-4360-4.
Variable Pulse Rate - Time since Trap Triggering Option for VHF Trapsite Transmitters - Show
This option results in a variable pulse period which is correlated to the elapsed time since the trap was triggered. The user specifies:
A pulse period indicating the trap is operational but has not been triggered
A pulse period to be transmitted immediately after the triggering event
The maximum elapsed time of concern since occurrence of the event (1 second to 1000 days, though typically periods would be 1 day or less)
A pulse period that corresponds to the maximum time of concern after the event occurs
The beacon can vary the pulse period with either a simple linear scale or a segmented scale of 2-8 pieces. A linear scale provides constant resolution. A segmented scale allows finer resolution of elapsed time immediately after the trap was triggered and coarser resolution later on, but is more complex to interpret. Each segment has resolution that is twice as coarse as the segment before it. Telonics provides a graph and a linear equation (linear) or equations (segmented) to convert an observed pulse period into an elapsed time. For precise times this option requires precise measurements of pulse period. The relationship between elapsed time and pulse period can be positive as shown in the graphs below, or negative as indicated in the formula below.
As an example using a linear scale:
Pulse period at trap triggering: 1200 ms (50 BPM)
Pulse period at maximum elapsed time of concern (1 day) later: 600 ms (100 BPM)
Equation: Elapsed seconds = [(Pulse Period) X (-144.0008)] + 172803
Resolution: 2 min, 24 seconds per 1 ms change in pulse period

Warranty: VHF Transmitting Subsystems - Show
The VHF Transmitting Subsystem includes the following main components: internal digital and radio frequency electronics comprising the transmitter, power supply (battery), exterior packaging, transmitting antenna and attachment. A refurbished Subsystem is warranted as if the Subsystem was purchased new, unless otherwise stated.
Telonics warranties only the following with respect to the Subsystem:
1.1 The internal electronics (excluding batteries) are warranted to be free from defects in materials and workmanship and to perform to the operational specifications over the specified operating temperature range as published by Telonics for the rated operational life of the Subsystem (as recorded on the final test data sheet accompanying the unit), up to a maximum of three (3) years from the date of initial shipment of the Subsystem by Telonics.
1.2 The exterior packaging integrity of hermetically sealed subsystems are warranted for the full operational life of the Subsystem, up to a maximum of three (3) years from the date of initial shipment of the Subsystem by Telonics.
1.3 The exterior packaging integrity of polymerically sealed subsystems are warranted for the operational life of the Subsystem, up to a maximum of one (1) year from the date of initial shipment of the Subsystem by Telonics.
Although each Subsystem is supplied with a power supply in the form of a battery, Telonics does not manufacture batteries (electrochemical cells), and therefore cannot warranty the battery lifespan, mechanical integrity or other battery performance issues. However, Telonics conducts extensive testing of all types of electro-chemical subsystems to determine suitability to the application. Once an electrochemical system is chosen for a configuration, testing procedures are employed at Telonics to evaluate every individual battery that is installed in each transmitting subsystem. Even using these advanced testing procedures it is not possible to determine a specific battery's lifespan or mechanical integrity.
Telonics conducts tests to assure that each unit is transmitting at the power level selected by the user. Actual range performance is a system characteristic dependent upon numerous conditions including receiver sensitivity and noise figure, receiving antenna tuning and pattern, transmitter antenna integrity, line of sight conditions in the field, and vegetation and habitat conditions and other factors specific to individual study sites. Therefore it is not possible to warranty a minimum range that will be achieved for units deployed in the field.
"Packaging integrity" as applicable to 1.2 and 1.3 above, is limited to normal wear as encountered on the animal.
It is the purchaser's obligation to make certain that it orders the correct size and type of Subsystem for the particular type and size of animal that the Subsystem will be applied to, and no warranty is expressed or implied for any failure to meet operational specifications due in whole or in part to use of an incorrect size or type of Subsystem.
No warranty is expressed or implied with regard to abnormal events or damage due to human actions such as gunshot damage, vehicle encounters, etc. Further, no warranty is expressed or implied with regard to damage resulting from misuse, accidents, unauthorized service, extreme conditions, or other causes not specifically enumerated herein.
The entire risk, as to the results and performance of the Subsystem, is assumed by the customer.
