position, the instrument will initiate a
yellow
light and
intermittent alarm, indicating that the sample-air is not
reaching the sensor. Correctly positioning the toggle will
terminate the intermittent alarm.
1.8.2 Arm/Disarm Switch:
This switch arms and
disarms the alarm horn. The switch is tripped ON and
OFF by inserting a small probe (a straightened paper
clip works well) through the small access opening in the
faceplate, and pushing gently until the detent is felt. It
may take a couple pushes to trip the switch. The horn is
armed when the ARM light is
green
. The horn is
disarmed when the light is unlit. NOTE The horn should
be disarmed only to temporarily silence it during
calibration by the technician.

Optional Accessories
1.9.1 Remote alarm:
The 12-volt DC remote alarm is a
high-intensity,
red
lens strobe light and high-decibel horn.
Unlike external alarms, this alarm does not require an
external power source. Installation instructions are
provided with the alarm.
Its use is recommended in a high-noise area or where the
monitor cannot be placed in a conspicuous location. The
alarm kit includes the alarm, stand, wiring connector, and
50 ft. cable. See Accessories in Section 9.1. With
additional cable, the remote alarm may be placed up to
150 ft. from monitor.

SETUP
2.1
Assembling the Monitor, Ref. Figure 2
2.1.1
Using the screws and instructions provided in
the mounting flange packet, attach the mounting flanges
to the instrument case.
2.1.2
Apply Teflon thread seal tape to the male
threads of the 1/4" x 1/8" reducer fitting and tubing
elbow, and assemble as shown in Figure 2. Make sure
the regulator is correctly installed so the air flows toward
the instrument. The tubing elbow may be rotated after
the instrument is mounted to enable the tubing to be
connected with minimum bends.
2.2
Mounting the Monitor
2.2.1
The simplest way to mount the CMS-1 is with
the mounting flanges provided, ref. Figure 2. Mount the
monitor in convenient location that is close to the
compressed air source. Refer to Section 2.3.2. The
monitor must be positioned upright and level to ensure
the flow meter responds correctly. Place the monitor on
a wall or panel, and mark the mounting hole locations.
Drill appropriately-sized holes, and secure with
fasteners.
DO NOT mount this instrument inside a blast
room. An operator wearing protective clothing
inside a blast room will not hear the alarm horn
when the instrument is in an alarm condition.
The alarm case is not designed to withstand the
continual impact of abrasive that takes place
inside a blast room. DO NOT mount this
instrument inside a paint room or in an
explosive or flammable environment. This
instrument is not rated for explosive
atmospheres. Refer to instructions within the
manual for installing a remote alarm, auxiliary
horns, lights, or safety shutdown devices.

Compressed-Air Connections
2.3.1 Air pressure requirements
2.3.2.1
If the compressed-air source pressure is
between 55 psi and 145 psi, no line pressure adjustment
is required. If line pressure is above 145 psi, a regulator
is required in the air line (before the monitor’s regulator)
to reduce pressure to be within the 55 to 145 psi
operating range. Pressure above 145 psi could damage
the monitor.
