Aiphone PC-359B Manuale utente
SYSTEM/MODEL: NEM
MODIFICATION: Installing PC-359B (or PC-454) with speaker and call button
COMPONENTS REQUIRED: 1. PC-359B or PC-454: Call holding circuit board, one per remote
speaker/call button
2. LT-1: 8 to 20 ohm transformer, one per remote speaker (Use
speaker with 1W handling capacity.)
INSTR/OPERATIONS: 1. If the existing speaker is 8 ohms, install the LT-1 transformer
with the BLUE wires to the speaker.
2. If the existing speaker is 45 ohms, install the LT-1 with the
RED wires to the speaker.
3. Make connections to PC-359B/454 as shown, being careful
not to short any exposed metal components on the PC board. (A
soldering iron and soldering skills are required for the PC-359B.
Wires are provided on the PC-454.)
4. Make sure that no moisture can come into contact with the PC
board when it is installed in its designated location.

- INSTRUCTIONS -
The PC-359B call holding circuit board provides the latching function when a call is placed from a remote station on the
NEM series Lamp Memory System. With this circuit board, a speaker and a "Normally Open" call button can be used as
a remote station where a standard sub station cannot be used. The NEM system impedance is 20 ohms, so either use
a 20 ohm speaker, or an 8 ohm speaker with the LT-1 matching trasformer.
