The SPST 24V 500mA relay contacts are Normally open and will close on alarm conditions when the
alarms are enabled. Relay contacts are always functional when the alarm is enabled. The relay will close
only during minimum and maximum alarm conditions. Two pen models have 2 sets of relay contacts
which operate independently. Relays will not operate under battery only power conditions.

The blue pen has a longer pen arm and records humidity or dew point (depending on your dip switch
selection, see pg. 4). The red pen has a shorter arm and records temperature. The pens are offset to allow
the red pen to glide under the blue pen. The blue pen indicates the correct time and the red pen
precedes it by 3/16 of an inch.
