Transmitters

Hog
Fixed UHF transmitter to base station

Jack


The JACK is a four channel fixed radio transmitter, compatible with the UHF base station. The transmitter is enclosed inside the weather proof housing containing the antenna .

The four channels can be  programmed to be Normaly open/closed, Input restore and trigger from .03 to 20 seconds.

There is a programable check-in transmission (every 1 to 256 hours)

The system may be used in conjunction with a UHF repeater to increase range

Retention of all programing options during power down.

All programming done via two built in buttons on PCB. No programmer necessary.   

 

 

Fixed UHF Transmitter to receiver

HOG


4 CHANNEL TRANSMITTER

The HOG is an very-customisable, 4 channel UHF transmitter. It is housed in a waterproof outdoor enclosure with an integrated whip antenna.

In low-power mode no power is used. When voltage applied to any of the inputs, this power is simultaneously used to supply the circuitry and activate the input, in which case the the HOG will transmit. After transmission the HOG will go into low power mode again, deactivating the input power.

The HOG has various transmission modes.
  • normal mode : transmit continuously while power is applied to one or more of the input channels.
  • beacon mode : transmit in bursts while power is applied to one or more of the channels. on and off times can be adjusted : ON: 0,5 to 10 sec.  OFF: 1 to 10 sec.
  • one shot mode : when power is applied to one of the input channels, the transmitter will transmit only once (time adjustable from 0,5 sec. to 10 sec.) It will reset as soon as power is removed from all the inputs.
  • The four channels can be set to different modes, for example: channel one and three can be used in normal mode while channel two and four is used in the timer mode. 
  • The timer mode can either be beacon or one-shot mode.


Portable UHF transmitter

sTG


LONG RANGE PORTABLE REMOTE CONTROL

The TG is a 3km FM remote transmitter used in conjunction with the R2/R4 channel receiver or the versatile RAC receiver.

This unit is ideal for panic systems in shopping centers, town house complexes, retirement villagers or to control any remote device.

The TG is supplied with either a wall mount bracket or belt  clip.

It has a telescopic antenna for additional range and is supplied in 1, 2,or 4 buttons combinations .

Transmitter module for Tracer alarm panel

TX MOD

ds


Add on the cost-effective transmitter module to the Tracer expansion socket and monitor it in your control room. The TX MOD comes both in VHF and UHF versions. Use the high power 15Watt VHF model if you want to monitor more than 5 km away. Otherwise the UHF model  may be used on a non-licenced frequency for shorter distances.

The combination of the Tracer and the TX MOD gives you a comprehensive feedback of alarms signals such as: Alarm with zone number, panic, battery low, battery restore, mains fail, mains restore, duress, arm, disarm, open, close, tamper, wireless tamper, wireless battery low.

 

 

 

 

 

 

 

 

 

 

 

VHF 4/8 channel transmitter to base station
 f The 4 or 8 channel transmitter is used in any situation where an output needs to be monitored, typically alarm panels and electric fences. Since the unit operates on VHF, many 10’s of kilometers may be covered.
The unit may be armed and disarmed via remote control.
Following are the features that make the "RKF T4 " one of the most versatile, efficient and innovative radio transmitters in the security market:
  • Up to eight 24Hr hard wired PROGRAMMABLE INPUTS.
  • Silent RADIO Remote PANIC button
  • Sends the conditions of all 4 inputs when any of the inputs are triggered.
  • All INPUTS are programmable to suit special installation requirement.
  • EEPROM memory for retention of options and code selections during "power-down".
  • Programmable to send a "check-in" transmission between 1 to 250 hours.
  • Programmable System Battery Low.
  • Inputs can be triggered by either a positive or negative signal.
  • Mains fail reporting

    VHF Contact ID communicator


    gThe Contact ID radio emulates a phone line and captures the alarm conditions sent by almost any alarm panel. After capturing this information, it is sent via radio up to 20km away.

    The system may transmit the user ID programmed into the alarm panel, or replace it with one programmed into the unit.

    The radio contact ID is transparent to the panel it monitors. It may be used for fire panels or any other device that sends Contact ID via telephone communicator
