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
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.
• Sensitivity adjustment wheel, no special tools required
• Reinforced diaphragm resists pressure spikes
• Two conduit entrances
• Both one- and two-switch models available

Architectural/Engineering Specifications EPS10-1 (SPDT), EPS10-2 (2/SPDT)
Model shall be an EPS10-1 or EPS10-2 pressure type waterflow switch as manufactured by System Sensor of St. Charles, IL. They shall be installed on the
sprinkler system with connection as shown on the drawings and/or as specified herein. Pressure switches shall be of the bellows-activated type. Switches shall
have a maximum service pressure rating of 250 psi and shall be factory adjusted to operate at a pressure of 4 – 8 psi. There shall be one (1) or two (2) SPDT
contacts rated at 10.0 Amp @ 125/250 VAC and 2.5 Amp @ 6/12/24 VDC. The contractor shall furnish and install, where indicated on the plans, pressure switches
according to appropriate NFPA standards. Switches shall be provided with a ½˝ NPT male pressure connection to be connected to the alarm check valve of a
“wet”sprinkler system, into the intermediate chamber of a“dry”system, or to a pre-action or deluge valve. They shall be activated by any flow of water equal to
or in excess of the discharge from one sprinkler head. Switches shall provide 1 knockout type and 1 open hole for ½˝ conduit fitting attachment and a ground
screw provision for electrical grounding. The switch enclosure shall be weatherproof and carry a UL 4x/NEMA 4 rating when used with proper electrical fittings
and conduit. The cover shall incorporate tamper-resistant screws. The unit shall be listed by Underwriters Laboratories, Inc. and approved by Factory Mutual.
