2.5.2.2 Mimic Termination Board
Each IDR-MD Mimic Termination Board can
drive up to 32 LED indicators or 32 relays (or
a mixture in groups of 8) on the IDR-M Mimic.
Each LED is wired across the two rows of
connectors as shown below. Section 2.4.2
shows how to connect relays.

2.5.3 LED Selection

Each LED is driven at 10-15mA. For typical
usage, any standard LED should give
satisfactory brightness.
If the mimic panel is installed in an area subject
to high ambient light levels, high-intensity or
low-current LEDs may give better results.
Note: Be aware that high intensity is often
gained by reducing the viewing angle.
EN54-2: 12.7.1 requires a viewing angle
of 22.5° at 500lux and 3m distance.

2.5.4 Relay Selection

The Mimic Driver Board is capable of handling
a maximum current of 80mA per relay. Relays
should therefore be chosen such that this value
is not exceeded.
The minimum pull-in voltage must be
obtainable when the system is running on
battery backup (battery at 21V) and with a
maximum ambient temperature of 45
Choose relays accordingly. (This consideration
may also affect the choice of external power
supply).
Some recommended industrial relays are listed
at left. Any other type of relay can be used
provided that the coil current does not exceed
80mA.
Diode protection should always be used.
