NH-1PA

Paging Adaptor for NHX System

Provides zone paging to an overhead speaker system

- INSTRUCTIONS -

Some applications for Nurse Call systems require paging to overhead speakers. The NH-1PA allows a button on the NHX master to be used for connection to an external paging amplifier. If multiple zones of paging are required, use one NH-1PA per zone.

NOTE: An NHX system installed with an NH-1PA included does not carry the UL 1069 listing.

NOTES:

1.When multiple NH-1PA's are included in the same system, each NH-1PA occupies a station button on the master station. This reduces the overall capacity for patient stations on the system.

2.The total amount of wire in a trunkage line including NH-1PA must not exceed 330'.

3.Adjust the volume of the paging speakers first from the volume control on the NH-1PA. Then adjust the volume control on the amplifier.

4.A system including zone paging does not carry the UL 1069 listing.

5.Only wiring concerning overhead paging is shown here. For complete installation and wiring information, please see the complete NHX Installation Manual.

CONTROLS AND SETTINGS:

DIP SWITCH SETTINGS (Located on bottomside of NH-1PA): Switch Values from left to right: 1-2-4-8

1. Set dip switches to the numerical value of the station button (1~10) to be designated as the PAGING button.

2. Station numbers are 1-10 vertically on the master station.

If the Paging button is the TOP button on a column (1), set dip switch 1 to ON. If the Paging button is the BOTTOM button (10), set switches 2 & 8 to ON.

3.Aiphone recommends setting the paging adaptor as station #10 on the first column (trunk line 1, wired as shown here.)

However, any station button can be designated for paging. The paging button is determined by (a) which trunk line the NH-1PA is wired to, and (b) the station number setting on the NH-1PA.

PAGING VOLUME (Located on front of NH-1PA):

This controls the overall output volume of the paging. Adjust to the desired level.
