HUMANTECHNIK A24730 Radio Alarm Transmitter Acoustic Instruction Manual
Congratulations on purchasing your radio alarm transmitter acoustic. We hope it will give you many years of reassuring operation. Please read through these operating instructions carefully. They tell you how to set up the system correctly and explain all the system’s features to you.
Product Description
Standard components
Please check if all following components are included:
- lisa radio alarm transmitter acoustic
- microphone cable 1 m
- stylus for setting the signal type
- 9 V block battery
- operating Instructions
- warranty card
If any parts are missing please immediately contact your dealer or the manufacturer directly.
Operating principle
A signalling system consists of at least one transmitter and one receiver. The radio alarm transmitter acoustic uses a microphone to pick up the signals emitted by a smoke detector, for example. It converts these signals into radio pulses (868.35 MHz) and transmits them to the receiver without the need for wires.
Special features
When a signal is detected, it is transmitted for a total of 22 seconds. This increases both the reliability and the range of the system.
Setting up the system
-
Inserting the battery
There is a battery compartment on the back of the radio alarm transmitter acoustic. Open it by sliding the cover of the battery compartment to the right of the receiver using your thumb. Connect a 9 V block battery to the connector plug, insert the battery into the battery compartment and close the device. When the battery is connected, the receiving signals may be triggered once.
-
Setting the correct radio channel
A special digital transmission process ensures that the radio signals are picked up without errors. This process also makes it possible to set 10 different radio channels.
When supplied from the factory, all radio alarm transmitters acoustic are set to channel 0. It is only necessary to set units to other channels, if you have several different users operating units in the same building.
Set the required channel by using a small screwdriver to turn the channel selector switch, which is located towards the top of the battery compartment, to the required channel number.
All transmitters and receivers must be set to the same channel.

Installing the microphone cable
Use the adhesive ring to glue the microphone to the sound outlet of the acoustic alarm (e.g. smoke detector, other alarms) and plug the microphone cable into the connection jack on the bottom of the radio alarm transmitter acoustic.
To do this, pull off the backing foil from the adhesive ring on the microphone.
For optimum function of the transmitter, its sensitivity dial switch must be set so the transmitter reliably responds to the acoustic alarm.

Setting the sensitivity
Set the sensitivity controller to its lowest level (turn to the anticlockwise stop).
Activate the acoustic alarm and gradually increase the sensitivity of the transmitter (by turning the dial clockwise) until the transmitter reacts to the acoustic alarm. -
Setting the type of signal
You can select one of the two signal types on the right-hand side of the radio alarm transmitter acoustic. Use the stylus that comes included with the device to push the signal selection switch to the desired setting.
Alarm signal
To indicate a general alarm signal (all LEDs will flash), set the signal selection switch to the top position. This will send an alarm to all the receivers that are switched on and set to the same channel.

Fire alarm
To trigger a signal from the smoke detector to the receivers which are switched on, set the signal selection switch to the bottom position.
Person call button
Pressing the person call button on the radio alarm transmitter acoustic causes a signal to be triggered on every receiver, which is set to the same radio channel as the transmitter. The person call button lamp lights up to indicate this. This makes it possible to call people who are in different rooms. Also, this button can be used for checking the system of its functioning even when the microphone cable is not connected.
Mains operation
You can also operate your radio alarm transmitter acoustic via the plug-in power supply unit (A-2992-0). To connect the PSU, insert the connector on the end of the PSU cable into the corresponding socket on the left hand side of the device. Then plug the power supply unit into the normal 230 V socket in your house.
Radio range
The radio signals are designed to have a range of 80 meters under optimum conditions.The following conditions may result in a reduced range:
- Signal transmission through building structures or vegetation.
- Interference from TVs, computer monitors and mobile phones. Under certain circumstances, this may prevent the receiver from functioning at all.
- Positioning of the transmitter at an unfavourable distance from surfaces, which reflect radio waves, for example floors and walls. This may lead to the signal wave being weakened or even cancelled out by the reflected wave.
- Metallic objects reduce the range due to the shielding effect of the metal.
- Particularly in towns and cities, there may be many other sources of radio waves, which can disrupt the original signal.
- Having units operating at similar frequencies located close to one another, may also result in mutual interference.
Positioning the radio transmitter
Bear in mind the following points when positioning the radio transmitter, in order to achieve the greatest possible range from the radio transmitter:
- The radio transmitter should not be set up close to devices, which emit powerful interference signals, such as TVs, computer monitors or mobile phones.
- The radio transmitter should not be placed on metallic objects, since otherwise the radio range will be restricted by metallic shielding.
Maintenance and care
The radio alarm transmitter acoustic does not require any maintenance. If the unit does become dirty, simply wipe it clean with a soft, damp cloth. Never use spirits, thinners or other organic solvents.
Do not set up the radio alarm transmitter acoustic where it will be exposed to full sunlight for long periods. In addition, it must be protected against excessive heat, moisture and severe mechanical shocks.
Note: This product is not protected against splash water. Do not place any containers filled with water, such as flower vases, or anything with an open flame, such as a lit candle, on or near the product.
Please make sure that the batteries are not exposed to excessive heat from such as sunlight, fire or anything similar.
Warranty
