3.7 4-Sounder Expander

• 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).

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 re 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 re 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.
