• All modifications of the device are forbidden for safety reasons. Damage caused by user modifications to the device is not covered by the warranty.
• Do not damage or shorten the cable.
• Only use for its intended purpose. Using the device in an unauthorized way will void the warranty.
• Damage caused by disregard of certain guidelines in this manual is not covered by the warranty and the dealer will not accept responsibility for any ensuing defects or problems.
• Temperature range from -60 °C to 180 °C.
• Excellent dielectric qualities.
• Weatherproof.
• Protects pipes, (water, fuels, etc.), faucets, filters, etc. against frost.
• May only be used directly on plastic pipes in PVC, PE-LD (Socarex ®  ), PPand similar.
• Only to be used on pipes carrying liquids.
• Do not immerse in liquids.
• Use: home, industry, etc.

Operation

• The cable must always be in direct contact with the pipe.
• Never interlace the cable. Make sure to leave enough space between the coiling when installing in a spiraled pattern (see table on the last pages of this manual).
• Refer to table on the last pages of this manual when installing the cable.
• Fix the cable end onto the pipe using the included clip.
• Insert the plug into an appropriate mains socket.
• 120, 120-0 and 120-1: cable without thermostat. Disconnect the cable with an ambient temperature of +10 °C and up.
• 120-0T and 120-1T: cable with thermostat. The thermostat will automatically switch on the cable as soon as the ambient temperature drops below +3 °C, and switch off with an ambient temperature of  +10 °C and up. Make sure to install the thermostat flat against the pipe. Fix it with insulation tape (e.g. PEREL article 1040-NPC). We recommend disconnecting the cable from the mains when the ambient temperature will not drop below +10 °C anymore.

Tips

• Protect the plug from condensation droplets by looping the power cord.
• Protect the cable against damage (sharp edges, rodents…).
• We recommend wrapping the cable in aluminum tape (PEREL article DTALU50) when using the cable on plastic pipes. This will ideally disperse the warmth.
  Warning: Install the cable in a regular pattern when used on nonmetallic pipes.
• Apply extra insulation onto the pipe to better protect it from frost.
• When using insulation, keep in mind the following tips:
• Use only insulation made from fire-retardant PE foam.
• Never use insulation with a thickness exceeding 13 mm.
•  Use the same insulation for the thermostat.
• Never connect an unwound cable to the mains.
• When the cable feels stiff, gently unwind and let it warm up before installing.
• Do not use the cable on pipes carrying liquids exceeding a temperature of 60 °C.
• Keep the cable away from flammable products to avoid fire risks.
• Always check the cable for damages before use.

Overview

General

The VMA449 is a voice-recording module based on the ISD1820 chip, which is a multiple message record/playback device. It offers single-chip voice recording, non-volatile storage, and playback capability for 8 to 20 seconds.

The VMA449 can be controlled by the onboard push buttons or by a microcontroller such as Arduino®.

Features

• Push-button interface, playback can be edge- or level-activated
• Automatic power down mode
• On-chip 8 Ω speaker driver
• Single 3 to 5 V power supply
• Can be controlled manually or by MCU
• Sample rate and duration can be changed by placing a resistor instead of jumper cap P2
• Default recording time of 10 seconds
• Dimensions: 37 x 54 mm

1. MIC – Microphone input. The microphone input transfers its signals to the on-chip amplifier.
2. REPEAT – Loop play the recorded sounds.
3. ISD1820 – Record/playback chip.
4.  FT – Feed Through. This mode connects the speaker driver to the microphone amplifier.
5. Lead out header – VCC (3-5VDC)/LED/NC/FT/GND – VCC/REC/PLAYE/PLAYL/GND.
6. P2 – Default short connection Rosc to 100 kΩ resistor R4, which means the record duration is 10 seconds.
7. PLAYL – Playback, level activated. When this input transits from LOW to High a playback cycle is initiated.
8. PLAYE – Playback, edge-activated. When a HIGH going transition is detected the recorded message will be played until the end of the recording.
9. REC – The REC input is an active HIGH record signal, the device records whenever REC is high. REC takes precedence over either PLAYL or PLAYE.
10. Speaker outputs – The SP+ and SP- provide direct drive for an 8Ω loudspeaker, or can also be used to connect to an amplifier (for example VMA408).

Operating Guide

1. Hold the REC button to record. The REC LED (D1) will light. Releasing the REC button will stop the recording.
2. Select the playback mode:
   • PLAYE: push one time and the full recording will be played.
   • PLAYL: the recording plays as long as the button is pushed.
   • REPEAT: move this sliding switch to the other position and the recording will continue playing time after time.
   • FT mode: move this switch to the other position, all the sound captured by the MIC will go directly
