NDR Lamp Memory Master Station with External Control Capability

NDR-10 NDR-20 NDR-30 NDR-40 NDR-10A NDR-20A NDR-30A NDR-40A

- INSTRUCTIONS -

The NDR Lamp Memory and External Control System is designed for communication between a central master station and remote intercom stations. In addition to communication to remote locations, an external device can be activated, such as activating a CCTV camera when the associated sub station is selected, or selectively controlling the corresponding door strike or maglock. All other features, functions, and components are the same as the standard NEM system.

ND-20AS	20-call Add-on Selector with selective output capability
ND-40AS	40-call Add-on Selector with selective output capability
RY-PA	Relay for selective output (1 per station requiring external contact)
PS-2420UL	24V DC, 2A Power Supply
N-series	Any model sub station with NA- or NE- prefix

IMPORTANT:

1.RY-PA must be used for each additional contact to isolate AC voltage from the intercom circuit.

2.Extra contact connections and L are on separate terminal block. NDR-30/40 have two terminal blocks.
