Optional Alarm Key (NRS 90230)

The paging stations employ two empty slots for retrofitting optional alarm keys or key-lock switches (also refer to chapter 5.2.3 Control Panel DPC 4550). For installing an additional alarm key you should only use the NRS 90230 extension kit.

Brief description:	optional pushbutton or switch for retrofitting DPC 4xxx-type paging stations to work
	as idling current-controlled	opener. The pushbutton - switch function can be
	configured on the hardware.

Supplied with the NRS 90230: 1 switch – pushbutton, complete with label field and cover

1connection cord, 4-pole

1resistor 10 k ohms

1lamp 6 volts

1selable cover

installation instructions:

1.Disconnect the paging console from the power supply.

2.Detach the bottom plate (6 to 8 screws, depending on the paging console model).

3.Prepare the installation site for the insertion:

￿Use a sharp, pinpoint tool (thick needle, pointed rat-tailed file, knife, etc.) to carefully pierce the pre-punched holes through – from the enclosure’s outside to the inside.

￿Configure the switch to operate as switch or pushbutton.

CHANGE FROM: SWITCH to PUSHBUTTON

￿ CAUTION: Install the switch so that the gap	figure 5.38	optional pushbutton/ switch
for changing the switch’s operation points
towards the TALK key. This allows for easy
changing its function even after it has been
inserted.

Note: Please make sure to solder the cables after the switch has been installed. Otherwise it is virtually impossible to slide the counter-nut over the body of the switch!

4.Adjust the switch and tighten it using the supplied milled nut.

5.Connect the cables and the resistor according to the circuit diagram on this page.

6.Please mind the sequence in which you connect the flat wire cables. The two outside wires 1(rt) and 4(gr) need to be soldered to the contacts of the lamp. The two inner wires 2(gr) and 3(gr) need to be soldered to contacts 1 and 2 of the switch. Polarity of either pair of wires is not critical.

7.Afterwards, you have to connect the 4-pole female plug to the corresponding OPTION 1 or OPTION 2 - terminal strip on the basic printed board assembly.

8.Re-attach the bottom plate.
