This product is intended for use in ordinary indoor locations of family living units and office workspaces. The CM-16A is not
designed to measure compliance with Occupational Safety and Health Administration (OSHA) commercial or
industrial standards.
Do NOT mount the unit in the garage. Do NOT mount the CM-16A where the normal ambient temperature is below 40°F (4.4°C)
or exceeds 100°F (37.8°C), or within 5 feet (1.5 meters) of a cooking or heating appliance.
6. The alarm relay of the CM-16A is a dry contact and rated at 1 Amp, 125V at 30 VA. It is not suitable for fan control use.
When connecting the units to remote buzzers or other devices, make sure that the load does not exceed the relay’s rating.
External buzzers must be capable of generating a sound output greater than 85 dBA at 10 ft.
INSTALLATION
1. In the configuration as normally shipped, the CM-16A has a three-part case. This allows the unit to mount flush to a wall
over a single gang electrical box (not included). If the back cover is removed, (remove the two screws inside), the CM-16A’s
mount on a two gang, old work box or a 4 X 4 electrical box, provided by the installer.
2. The detector may be installed on either a ceiling or a wall. If installed on a peaked, gabled, or sloped ceiling, it should be
located about 3 feet from the highest point. The unit can be placed vertically or horizontally on a wall, so the information on
the front of the CM-16A can be read in a normal manner. Do NOT mount the CM-16A in a corner. Use the same spacing as
for smoke detectors-- 30 foot (9 meters) centers, 900 sq. feet (83 sq. meters) per detector.
3. The CM-16A‘s have terminal strips to connect to the cables from the control panel or other device. When connecting the
unit, follow good wiring practices, and ensure the power is turned off. Access to the terminal strip will be easier if the back
cover is off.
4. Ensure that the CM-16A is connected to a continuous source of power (not controlled by a wall switch). The CM-16A power
consumption figures represent worst-case conditions under AC power; DC performance may vary.
5. See wiring diagram for information on connections of the CM-16A. 3M™ Macurco™ recommends a minimum of 22 AWG
wire for runs up to 200 ft., and 18 AWG wire for longer runs.
