Alarm Pressure Switches
Fig. RDEPS10-1 and RDEPS10-2
Important
This instruction manual contains important information about the
installation and operation of supervisory pressure switches. Purchas-
ers 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 instructions 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
Protection Systems
NFPA 13D: Standard for 1 and 2 Family Dwellings and Manufac-
tured 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. Rapidrop 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 adjust-
ment 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.
a. Mount the device directly to the line via the 1⁄2" NPT pressure
connection. The use of teflon pipe sealant tape is recommend-
ed. Be sure the fitting is tight enough to prevent leaks.
b. Apply tightening torque to the black plastic hex portion of the
device.
3. Wire the device in accordance with the National Electrical
Code. Two 7/8" diameter conduit connection holes have been
provided in the mounting plate to accept standard 1⁄2" conduit
fittings (one is removable knock-out type). If a NEMA 4/UL 4x
(waterproof unit) is required, waterproof flexible metallic conduit
and appropriate conduit fittings must be used. Recommended
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 2 and Table 1).
