EPS10-1 AND EPS10-2

Alarm Pressure Switches

System Sensor EPS10 Series switches are designed

for use in wet, dry, deluge, and pre-action automatic

sprinkler systems to indicate a discharge from

a sprinkler.

Features

• Sensitivity adjustment wheel, no special tools required

• Reinforced diaphragm resists pressure spikes

• Two conduit entrances

• Both one- and two-switch models available

The EPS10-1 has a single SPDT switch while the EPS10-2 model

contains two SPDT switches. The EPS10 Series features field

adjustable pressure sensitivity to provide an alarm response between

4 and 20 psi. It is factory set to respond at 4 – 8 psi on rising or falling

pressure. The pressure adjustment wheel requires no special tools

and does not affect switch synchronization on the EPS10-2. The

EPS10 Series switches are NEMA 4 rated.
