Installation

1. As shipped, the CM-E1 faceplate is mounted on the enclosure's rear-housing component. This enclosure configuration allows
the unit to be surface mounted flush on a wall. Wiring is routed through an access area on the base of the rear housing.
2. A thin mid-plate enclosure component is also supplied with the CM-E1. Using the supplied screws, this mid-plate
component is used to mount the CM-E1 on a 2 x 4 inch (5.08 cm x 10.16 cm) switch box - single-gang or "handy",
provided by the installer. The CM-E1's faceplate component (with the detector attached) is then mounted on the mid-
plate component.
3. 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 (1 meter) from the highest point. The unit can be placed vertically or horizontally on a wall, so the
information on the front of the CM-E1 can be read in a normal manner (not upside down). Do NOT mount the CM-E1 in a
corner. Use the same spacing as for smoke detectors-- 30 foot (9 meters) centers, 900 sq. feet (83 sq. meters) per detector.
4. Electrical connections to the CM-E1 are made via the supplied six-conductor pigtail cable. The pigtail cable is first
connected to the control panel wiring by means of the supplied wire-nuts (refer to the diagrams for proper pigtail
wiring). The pigtail cable's connector then snaps into the mating connector on the back of the CM-E1 detector, allowing
easy installation and replacement of the CM-E1. For proper detector operation, ensure that the CM-E1 is connected to
a continuous source of power (not controlled by a wall switch). The CM-E1 current draw figures represent worst-case
conditions and will not vary as the applied DC voltage varies.
5. The alarm control panel zone inputs must be terminated with end of line resistors (E.O.L.R.), which are provided with
the panel.
6. When using the CM-E1 with normally closed initiating circuits, remove the jumper.
