FANS, FLUORESCENT LIGHTING AND NON-DIMMABLE LOADS
MultiMate™ dimmers, timers, switches and occupancy sensors are designed to control dimmable lighting
loads.
Sometimes these products need to control non-dimmable loads, for example fluorescent lighting, non-
dimmable LED lamps, or bathroom exhaust fans.
Direct wiring of these loads to MultiMate™ products may cause incorrect function of the load or the
MultiMate™ product.
To Control fans and non-dimmable loads
The MMSR MultiMate™ Slave Relay presents a dimmable load to
MultiMate™ devices. When the dimmer level exceeds a threshold,
the relay is operated and switches on a non-dimmable load.
Combinations loads are possible on a dimmer: a dimmable LED
load may be used on the same circuit as non-dimmable loads. In
this case, when the dimmer level is higher than a threshold, the
relay is operated to switch the non-dimmable load(s) on and the
dimmable load will continue to respond normally. This is shown in
the wiring diagram below.
Properties of the MMSR Slave Relay
The Slave Relay has voltage-free contacts, and is rated at 10AX.
SELV load control is possible when using the isolating barrier that
is included.
The Slave Relay is suitable for use with trailing edge phase control dimmers. The Slave Relay can satisfy the
load requirements of LEDsmart+ dimmers / timers / switches or occupancy sensors by itself. Using an
additional dimmable lighting load is optional.
