4-Sounder Expander - Teletek electronics MAG8Plus Installation And Operation Manual

3.7 4-Sounder Expander

Figure 15.
Performance and Connecting of the 4-Sounder Expander
There is a correspondence between the zone numbers and the sounders - ZONE 1 of
the 4-zone expander corresponds to SOUNDER 1 of the 4-sounder expander, ZONE
2 to SOUNDER 2, and so on. In case of fire in ZONE 1, SOUNDER 1 will operate
continuously and Sounders 2 ÷ 4 of the expander will be pulse activated - 2 sec. sound/
2 sec. silent.
The method of adding of 4-sounder expander is analogical to that of adding a 4-zone
expander module, see Figure 14. Note: At Step 3 mount the resistors R-10K from the
supplied spare parts kit (position 16, page 31) to the sounder expander terminals.
ATTENTION: Do not connect or disconnect the expander when the power
!
is on! Before connecting or disconnecting the expander you SHOULD
check whether the main and the stand-by power supplies are OFF!
Note: Only a module of the same type can be added to the 4-sounder
expander. For the proper performance of the fire alarm panel observe
!
the connection sequence presented in Figure 16a. In case of improper
connection (Figure 16b), an error signal will be generated when the
power supply is switched on - the LEDs of the zones connected after the
4-sounder expander will begin to blink and the GENERAL FAULT LED
remains permanently lit.

• 1 - Mounting holes.
• 2 - Connector for connecting of additional
4-sounder expander.
• 3 - LED indication for troubles in the sounder
circuits. In case of a trouble in any of the sounder
circuit SND1 - 4 the LED of the respective
sounder circuit will light on together with
GENERAL FAULT and SOUNDER FAULT/
DISABLE indicators on the front panel.
• 4 - Connector for connecting:
а) To a 4-zone expander.
b) To a previous 4-sounder expander.
c) To the control module.*
• 5 - Mounting holes for placing a lightpipe for the
front panel LED indication, Position 15, page 31.*
• 6 - LEDs Sounder status indication.*
* Note: Just in case, when the panel is in
Repeater Mode (a jumper is set on the SLAVE
position).
