Accessories
S1A
Line Voltage rated End-Switch assembly for all new ND and URD style
dampers. Easily attaches over the top of the motor. Can operate
blower motor, combustion air, hydronic zone valve or circulator,
among other applications.
MAN / MA-5P
The MAN is a 2 Position, power-open, power-close actuator. Used
on old-style, standard opposed blade dampers. The MA-5P is a 5 Position,
power open, power close actuator used with old-style, standard opposed
blade dampers. MAN and MA-5P actuators are only interchangeable
with other MAN or MA-5P units.

MRK
Motor replacement for models ND, EBD, URD, and RDN dampers. Dampers
such as the RDN will also require the purchhase of a DHK (Damper
Hardware Kit). If unsure if you require a DHK please contact our
sales department. Notice: The MA-ND5 (power open/power close) motor
actuator cannot be used to replace an existing MA-RSD (spring return)
motor actuator.
DHK
