Connecting The Sounders Circuits; Connecting The Fault And Fire Relays; Class Change Function - Teletek electronics MAG2 User Manual

• Operate ALL detection devices applicable to this zone, to ensure correct receipt of a fire
signal and the correct operation of the panel controls. Refer to the User Instructions on
the inside of the panel.
• Repeat the connection process for the other zones stated above. ENSURE the supply
voltages are initially disconnected prior to each stage.
Once the connection of the zones is completed, connect and test any
!
of the other auxiliary circuits BEFORE connecting the external sounder
circuits.

5. Connecting the sounders circuits

• Disconnect the mains power supply and the battery connection.
• Remove the EOL-Resistor from the terminal block of sounder circuit 1 (SND 1) and fit
to the last sounder of circuit one:
• Check all sounder connections are made.
• Connect sounder circuit ONE to the panel terminal block.
• Apply mains and battery power.
• Press RESET.
The panel should be in the 'NORMAL MODE'.
• Activate a zone Call Point. The sounders should operate. Press the RESET button.
Repeat the connection process for the second external sounder circuit, as stated above.
ENSURE the supply voltages are initially disconnected prior to each stage.
If General Fault and SOUNDER FAULT / DISABLE LED's illuminate, there is
a wiring / connection problem. Check the polarity of the connection of each of

the devices, the polarity of the connection of the devices to the Panel terminal
block or whether an earth fault exists.
6. Connecting the FAULT and FIRE relay circuits
FAULT and FIRE Relays - The on board relays volt free change over terminals are
for low voltage use only. Attention: Mains supply MUsT NOT BE APPLIED to these
terminals.

7. Class Change Function

To use the class change function connect the terminals of a switch with normally open
contacts to the CC (Class Change) clamps of the main module terminal. The working
mode of the sounders will be:
- when the switch is pressed - one second sounder on, one second sounder off;
- when the switch is depressed - the sounder is off.
