Plug'n Power Remote Controller/Timer (610-2670) Intercoms & Power Interruptions Faxback Doc. # 18458 PLUG 'N POWER AND INTERCOMS Some intercoms also send signals through the house wiring. If you have this type of system, it is likely that it will interfere with the operation of your plug 'n power system. However, it will interfere only when both systems are in use at the same time (if you leave an intercom in a child's room in the transmit mode, for example). If this is a problem, use an intercom that has its own separate wiring system. POWER INTERRUPTIONS When power is restored after a power failure, lamp dimmer modules and both types of wall switch modules default to the OFF mode. Appliance modules remain in the state they were in before the power failure. (/all-01/03/96)
