included 4x4 box, or flush mounted
using customer provided 4x4 box
installed in finished wall
Horn Alarm
120 vac alarm (240 vac version
available), surface mounted
12 or 14 AWG
Optional - Purchased separately from monitor, Install in
mechanical room so that it can be seen and heard from all
areas, control Strobe portion with LOW alarm relay,
control Horn portion with HORN relay
Optional - Purchased separately from monitor, Install
outside mechanical room so that it can be seen prior to
entrance into area, Control with LOW alarm relay
Optional - Purchased separately from monitor, Install in
mechanical room so that it can be heard from all areas
Provided by customer, Install in accordance with NEC and
local codes, Provide power for alarms from same circuit
providing power to monitor, use alarm relays to switch line
voltage

Field Wiring
Analog 1 output, 0-10 volts, provides
measurement of current area being
monitored
Analog 1 output, 4-20 mA, provides
measurement of current area being
monitored
Analog 2 output, 0-10 volts and 4-20
mA, provides current area being
measured
18 or 22 AWG
LOW, MAIN and HIGH alarm relays,
each with 4 sets of dry contacts
Individual Zone Alarm Output, provides
8 relays, each with 1 set of NO/NC
contacts, for control voltages only (24
vac or vdc only)
18 or 22 AWG
Standard feature of monitor, Optional connection – useful
in measuring trends, DO NOT use to determine alarm
conditions, to do so defeats key features of the refrigerant
monitor
Optional feature of monitor, used for control systems that
prefer 4-20 mA input, DO NOT tie control system loop
power to monitor 24 volts
Optional feature of monitor, Order qty 2 OP 001 to have
analog 2 installed, Not normally used, Typically most
sample areas are in the same room
Provided by customer, Install in accordance with NEC and
local codes
Standard feature of monitor, NO and NC contacts are
available for BMS connection
Optional feature of monitor, provides indication of which
area is in alarm, can be selected for different alarm
configurations, refer to separate Individual Zone Alarm

Provided by customer, Install in accordance with NEC and
local codes
