For Deringer Models 20/20X/30/30X/40/40X/50/50X
1. The supervisory switch assembly contains two single
pole, double throw, pre-wired switches. A primary and
an auxiliary.
2. Switch ratings:
10 amps @ 125 or 250 VAC/60 Hz
0.5 amps @ 125 VDC
0.25 amps @ 250 VDC
3. Primary and Auxilary, supervise the valve in the “OPEN”
position.
4. Primary has two #18 insulated wires per terminal, permit-
ting complete supervision of leads. Auxiliary has one #18
insulated wire per terminal. This double circuit allows for
the operation of two separate electrical devices (audible
alarms, indicating lights, etc.) in close proximity to the
valve installation.
5. A #14 insulated ground lead (green) is provided
Primary (S1) For connection to a supervisory circuit of
a UL Listed alarm control panel
Auxilary (S2) For connection to auxiliary devices per
the authority having jurisdiction
Gear Box Wiring Installation
NOTE: The below diagram shows a connection between terminals (S1: Yellow / S2: Yellow with Orange Stripe) and the normally Open
Terminals (S1: Brown / S2: Brown with Orange Stripe). In this example the signal switch will remain open (No current through switch)
as long as the valve remains Fully Opened. Once the Valve begins to close the signal switch will change from open to close (current
will flow through switch). Only S1 (two leads per terminal) may be connected to the fire alarm control panel. The connection of the
alarm switch wiring shall be in accordance with NFPA 72 and the auxiliary switch per NAPA 70 (NEC). Remember to cap off any
unused wire and that your conduit connections are water tight.

Air Gap Assembly Applications & Limitations
An Air Gap Assembly (attached to relief Valve) will capture and evacuate
light to moderate water discharge from the Relieve Valve caused by daily
fluctuation in system/supply pressure.
An Air Gap Assembly will NOT capture and evacuate the
Maximum Relief Valve Discharge Rate caused by catastrophic
valve or system failure.
An auxiliary drain (separate and independent of the Air Gap Assembly) is
REQUIRED and MUST be properly sized for the Maximum Relief Valve
Discharge Rate. Ames®shall not be responsible for any damage caused
by lack of auxiliary drain, location of auxiliary drain or undersized auxiliary
drain. If the installer does not clearly understand this requirement
DO NOT install the RP/RPDA & Air Gap Assembly.
Ames Air Gaps Include:
• Air Gap drain mounting bracket
• Air gap drain shield
• Air Gap drain reducer
• All required hardware
