IMPORTANT

Please Read Carefully and Save

This instruction manual contains important information about the installa-

tion and operation of supervisory pressure switches. Purchasers who install

switches for use by others must leave this manual or a copy of it with the user.

Read all instructions carefully before installation, following only those instruc-

tions that apply to the model you are installing.

Before installing any alarm device, be thoroughly familiar with:

NFPA 72: National Fire Alarm Code

NFPA 13: Installation of Sprinkler Systems

NFPA 25: Inspection, Testing, and Maintenance of Water-based Fire Protec-

tion Systems

NFPA 13D: Standard for 1 and 2 Family Dwellings and Manufactured Homes

NFPA 13R: Standard for Multi-family Dwellings

Other applicable NFPA standards, local codes, and the requirements of the

authority having jurisdiction.

Failure to follow these directions may result in failure of the device to report

an alarm condition. System Sensor is not responsible for devices that have

been improperly installed, tested, or maintained.

CAUTION

Do not use in potentially explosive atmospheres.Do not leave unused wires exposed.

OPERATION

As pressure changes, a diaphragm actuates 1 or 2 snap action switches. The

pressure switch actuation is determined by adjustment settings.

INSTALLATION

1. Remove Cover

Cover is held on by two screws.

2. Mounting the Switch

The device is designed to be mounted in the upright position; side mounting

is also acceptable. Locate it where vibration, shock, and mechanical loading

are minimal. Refer to piping diagram above (Fig. 2 and 3).

a. Mount the device directly to the line via the

⁄2" NPT pressure con-

nection. The use of teflon pipe sealant tape is recommended. Be sure

the fitting is tight enough to prevent leaks.

b. Apply tightening torque to the black plastic hex portion of the device.

WARNING

High voltage. Electrocution hazard. Do not handle live AC wiring or work on

a device to which AC power is applied. Doing so may result in severe injury

or death. When utilizing switches at voltages greater than 74 VDC or

49 VAC , means to provide all-pole disconnection must be incorporated in

the field wiring, such as a circuit breaker.

3. Wire the device in accordance with the National Electrical Code. Two

/8″

diameter conduit connection holes have been provided in the mounting

plate to accept standard

⁄2″ conduit fittings (one is removable knock-out

type). If a NEMA 4/UL 4x (waterproof unit) is required, waterproof flex-

ible metallic conduit and appropriate conduit fittings must be used. Rec-

ommended connectors are Thomas and Betts PN 5332 (180° coupling),

PN 5352 (90° coupling), and PN 5262 seal ring.

4. Connect wiring to terminals (see Figure 4 and Table 1).
