PM321/PM322B Multiplex Lamp Control Modules
The PM321B and PM322B multiplex lamp control modules are for use with NC300II series nurse call system patient stations IR319B and IR320B, and the SF401DIG pillow speaker. The modules provide for ON/OFF control of two lamp sources through the pillow speaker. Lamp sources are typically the overhead room lamp and a separate reading lamp. Circuitry for low-voltage switching of the lamps is to be provided by others.

Turning the lamps on or off is accomplished by pressing the appropriate switches on the corresponding pillow speakers. The lamp control modules can also be directly mounted to stations equipped with PM311C or PM312C pillow speaker intercom modules.

If desired, standard SF41 series pillow speaker or SF401A call cords may be used without removal of the PM321B and/or PM322B modules.
