4
The Micro-Link keypad operates much like the larger Opti-Link
keypad. The major dierence is that there is only one large key,
performing 3 functions instead of separate Pursuit, Arrival and
Reset keys. The associated Interface/Output Receiver has 6 high
current output stages for controlling external equipment.
Introduction
Installation Requirements and System Limitations
The Micro-Link System is designed for 12-volt operation only.
The Interface Output/Receiver unit must be mounted in
a well ventilated dry location and away from heat sources,
preferably on a metal surface to conduct heat away. UNDER NO
CIRCUMSTANCES SHOULD THE UNIT BE MOUNTED INTO
AN ENCLOSED SPACE WHICH WOULD ALLOW HEAT TO
BUILD UP
Maximum output per relay – 5 Amps.
Maximum total output – 15 Amps
EACH OUTPUT MUST BE FUSED APPROPRIATELY FOR THE
LOAD CONNECTED TO IT.
Pursuit / Arrival / Reset
External ‘999’ Input
Walk Test
Sleep / Wake-up / Sleep Test
Audio / Visual Warnings
Low Light Keypad Dimming
Operation
In normal operation the large key, SW7, functions as a reset
switch. If no channels are selected, pressing SW7 will cycle
between a pre-dened Pursuit Setting, an Arrival setting and
nally a Reset. When in Pursuit mode the key will light blue.
When in Arrival mode the key will light red.
Connecting pin 4 on the keypad connector to +12V via an
external momentary switching source will enable the Pursuit
setting on the keypad.
Pressing and holding the large button, SW7, when not in either
Pursuit or Arrival mode initiate a walk test. Each channel will then
be lit individually for a few seconds allowing a test of all outputs.
The unit will automatically go to sleep after an hour if no
channels are selected and the supply voltage is less than 13.5
volts (i.e. the engine is not running).
The unit will wake-up when a key is pressed or when the supply
voltage exceeds 13.5 volts.
For test purposes the unit can be put to sleep by pressing and
holding SW6 and SW7 for a few seconds.
As a channel on reminder, the warning LED will ash and the
unit will beep every 30 seconds whenever a channel is on. The
warning LED will ash continuously when the battery voltage falls
below a critical level 9.5volts.
Finally the LED will light continuously when the programming
lockout is disabled.
When the ambient light level falls below a pre-set level the
keypad illumination will automatically dim. This is controlled by
the LDR (light dependent resistor) adjacent to SW1. DO NOT
COVER THIS DEVICE.
