GENERAL SAFETY INFORMATION Intended Use The CM-E1 is a low voltage (9-32 VDC) detector of Carbon Monoxide (CO). The CM–E1 is designed for connection to UL Listed Fire Alarm/Burglary Control Panels. NOTE: Any time the words “Control Panel” or “Alarm Panel” or “Alarm Control Panel” are used in these instructions, they refer to a UL Listed Fire Alarm/Burglary Control Panel. Alarm control panels that work on 12 or 24 VDC can provide battery backup to the CM-E1 detectors.
Transient CO situations can occur: 1. Excessive spillage or reverse venting of fuel burning appliances caused by outdoor ambient conditions, such as: a) Wind direction and/or velocity, including high gusts of wind. Heavy air in the vent pipes (cold/humid air with extended periods between cycles). b) Negative pressure differential resulting from the use of exhaust fans. c) Simultaneous operation of several fuel-burning appliances competing for limited internal air.
CM-E1 may not function effectively below 40F (4.4°C) or above 100F (37.8°C). Using the detector outside of this temperature range may adversely affect product performance and result in sickness or death. (UL 2034) General Description The CM-E1 is for use with UL Listed Fire Alarm/Burglary Control Panels that have 12 to 24 VDC power and 12 to 24 VDC alarm initiating circuits.
For best operation, mount a CM-E1 in the hallway near each bedroom or office area. In addition, another CM-E1 may be mounted just inside the door from the adjoining garage. Consider placing another detector in a bedroom or office that is adjacent to a furnace room. ! WARNING This product is intended for use in ordinary indoor locations of family living units and office workspaces.
The relay of the CM-E1 is a dry contact and rated at 100mA, 40VDC. It is not suitable for fan control use. When connecting the units to remote buzzers or other devices (all buzzers or "other devices" must be UL approved), 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 (3.048 M). Power Up ! WARNING When the unit is turned on it performs a self-test, which activates the audible and visual alarms.
The CM-E1 continuously monitors the ambient air at the sensor. If the CM-E1 measures levels of CO greater than the danger level, the RED light will turn on, the Alarm Relay will switch to actuate the alarm circuits in the control panel, and the buzzer on CM-E1 units will sound. The CM-E1 is programmed to alarm if the danger levels of carbon monoxide are exceeded, which are time and concentration-related.
Transient CO situations can occur: 1. 2. 3. 4. (UL 2034) Excessive spillage or reverse venting of fuel burning appliances caused by outdoor ambient conditions, such as: a) Wind direction and/or velocity, including high gusts of wind. Heavy air in the vent pipes (cold/humid air with extended periods between cycles). b) Negative pressure differential resulting from the use of exhaust fans. c) Simultaneous operation of several fuel-burning appliances competing for limited internal air.
Seven years after the CM-E1 is installed the end-of-life signal will be activated indicating that the CM-E1 has reached the end of its service life and needs to be replaced. The end-of-life signal will cause an open circuit in the normally closed (NC) Trouble Relay to provide actuation of the signal circuits. The status LED will flash alternate AMBER and OFF every 2 seconds and the CM-E1 buzzer will emit a short "chirp" every 50 seconds.
LIMITED WARRANTY The Macurco CM-E1 Carbon Monoxide Detector is warranted to be free from defective material and workmanship for a period of two (2) years from the date of manufacture (stamped on the unit). If any component becomes defective during the warranty period, it will be replaced or repaired free of charge, if the unit is returned in accordance with the instructions below.
