Programmable input (Reset)

There is a programmable input that can have several alternate
functions. As a factory default it is configured as a Reset input that
will reset all alarms and relays. It is intended to be switched using
volt free contacts that are normally open. Leave the input open
circuit if not used.

FRONT PANEL LEDS – WHAT THEY SHOW
The front panel indicators use the following colour convention:
Green
Red
Yellow
For simultaneous faults/alerts on the same LED, the priority order is:
ON (highest) > blink > double blink > triple blink (lowest)
The meaning of all the front panel indicators are detailed in Tables
1A and 1B below:
To test if all the front panel LEDs are functioning, hold the TEST
button while the device is powered on. The firmware version
number will be displayed for 2 seconds on the Channel 1 smoke
level LEDs and then the front panel LEDs are illuminated, in the
following sequence: all the red LEDs, all the yellow LEDs, all the
green LEDs.
