TELETEK SensoMAG R20 Conventional Fire Alarm Rate-of-Rise Heat Detector

Product Information

SensoMAG R20 Conventional Fire Alarm Rate-of-Rise Heat Detector

The SensoMAG R20 is a conventional fire alarm rate-of-rise heat detector that is compatible with any conventional fire panel with a fire alarm threshold between 10mA and 15mA (between 10mA and 30mA with B24RD firebase). It can be used with four different base types: B12L/U, B24, B24D, and B24RD. The detector has been tested by EVPU and meets EN 54-5:2017+A1:2018 Detector Class A1/R standards. The detector has a compact design and is easy to install. It is equipped with LED indication for proper operation and is suitable for use in a variety of settings including commercial buildings, offices, and homes.

Product Usage Instructions

1. Choose an appropriate location to install the fire detector. Refer to the installation instructions provided in the manual.
   Note: Do not install the detector near natural heat sources such as above cookers, ovens or fireplaces.

2. If you want to lock the detector to the base, remove the little tooth (with the triangle shape) and break the plastic key off the base. Keep the plastic key in a safe place to be able to open the detector later.

3. Mount the firebase on the ceiling of the protected premises using fixings according to the mounting surface.

4. Disconnect the line power before installing the detector. Connect the detector base to the fire panel using the wiring diagram provided.

5. Insert the detector into the base and rotate clockwise until it drops into place. Continue to rotate the detector until it locks to the base – a click is heard.

6. If the detector has been locked to the base, when opening it for scheduled maintenance service and cleaning, you have to use the plastic key. Lightly press with the plastic key into the base opening and at the same time rotate the detector head counter-clockwise.

7. In case of removing the detector’s PCB for service maintenance, when mounting it back, find the colored dot sticker on the PCB and align it to the mark on the plastic body (visible from the outside). The hole next to the colored dot has to align with the pin on the plastic body. Gently press downwards to fix the PCB in place.

8. Test the detector for proper operation and LED indication.

Follow these instructions carefully to ensure proper installation and operation of the SensoMAG R20 Conventional Fire Alarm Rate-of-Rise Heat Detector.

Installation Instruction

Conventional fire alarm Rate-of-Rise Heat Detector

ATTENTION: Read carefully these installation Instructions before installing the device! The detector SensoMAG R20 is compatible with any conventional Fire Panel with fire alarm threshold between 10mA and 15mA (between 10mA and 30mA with B24RD firebase). The detector SensoMAG R20 can be used with 4 base types:

• B B12L/U – Base with relay output (not covered by EN 54-5);
• C B24 – Standard base, low profile; B24-HP – Standard base, high profile;
• D B24D – Standard base with Schottky diode;
• E B24RD – Standard base with Schottky diode and increased alarm state current.

1. Choose the proper place for installation of the fire detector. Refer to the given installation instructions. Note: Do not install the detector near to natural heat sources, e.g. above cookers, ovens or fire places.

2. If you want to “lock” the detector to the base remove the little “tooth” (with the triangle shape) and break the plastic key off the base. Keep the plastic key in safe place to be able to open the detector later.

3. Mount the fire base on the ceiling of the protected premises using fixings according to the mounting surface.

4. Connect the detector base to the fire panel using the wiring diagram.
   ATTENTION: Disconnect the line power before installing the detector!

5. Insert the detector into the base and rotate clockwise until it drops into place. Continue to rotate the detector until it locks to the base – a click is heard.

6. If the detector has been locked to the base, when opening it for scheduled maintenance service and cleaning you have to use the plastic key. Lightly press with the plastic key into the base opening and at the same time rotate the detector head counter-clockwise.
   ATTENTION: In case of removing the detector’s PCB for service maintenance, when mounting it back, find the colored dot sticker on the PCB and align it to the mark on the plastic body (visible from the outside). The hole next to the colored dot has to align with the pin on the plastic body. Gently press downwards to fix the PCB in place.

7. Test the detector for proper operation and LED indication.

TEST AND MAINTENANCE

1. Apply power to the detector.
2. Wait for 30 sec.
3. Apply the heat tester (Cordless Heat Detector Tester or Heat Tester 110V>240V) at a distance 20cm to test the heat part of the detector. Within 8 sec the fire detector will enter in fire condition. Both LEDs will light up.
4. Power off the detector for 2 sec minimum. After resetting the detector will enter in duty mode and the LEDs will light off.

The service maintenance periods for the detector should be executed as follows:

1. Inspection for visible physical damage – weekly.
2. Operational test in real conditions – monthly.
3. Check and clean dust contamination – six months.
4. Check and clean base and head contacts and connections – annually.

WIRING DIAGRAM

• ATTENTION: When the EOL-module is only a capacitor, IT IS OBLIGATORY TO CONNECT a 100K resistor in parallel at the beginning of the line!
