DELAY RELAYS
Delay relays are used to eliminate false pressure transients
from sounding high alarms (TD-69). The TD-73 is used
to prevent furnaces and compressors from quick restarts.

AUDIBLE ALARM
OMEGA’s Model 70A audible alarms are
the latest development in solid sound
production. When 120 Vac is applied to
them, a piezoelectric transducer operates
as a solid state oscillator, resulting in a loud
alarm tone. A small, 29 mm (1.13") diameter
hole is required for panel mounting.
See section C for more details.

HIGH-RELIABILITY SOLID
STATE RELAYS
Solid state relays are used for switching
large loads and, in conjunction with
pressure switches, they extend the
power rating of the switch.
