analog systems and controls PRODUCT SPECIFICATION CM9760-ALM Alarm Interface Unit ALARM GATHERING UNIT FOR UP TO 64 ALARM INPUTS Product Features • Each Unit Can Handle up to 64 Alarms Up to Four Units Can Be Daisy-Chained from One CM9700 Series CM9760-ALM (FRONT) CC1 SERCOM Port for a Total of 256 Alarms Alarm Inputs Can Be Configured in Groups of 16 for Supervised or Unsupervised Mode Alarm Inputs in Groups of 16 Can Be Wired Either Normally Open or CM9760-ALM (REAR) Normally Closed Each Unit Has One Common Alarm Relay Output Each Unit is Powered by an Autoranging Power Supply The CM9760-ALM uses an RS-232/422 communication interface with the CM9700 Series system controllers. The unit can be 1.75 CM9760-ALM (4.45) 9760 Alarm Interface Unit remotely placed with respect to the controller, from where it can Made In USA communicate back to the central system when an alarm occurs. The 17.40 (44.20) alarm unit is capable of handling up to 64 alarm inputs. The front of the CM9760-ALM has two 10-position DIP switches, which allow the configuration of each unit. Also, a red LED flashes 8.54 (21.69) whenever there is a valid alarm condition. The relay output connector accepts a screw terminal adapter. When a valid alarm condition is sensed, the alarm unit will activate the relay. It will deactivate only when the alarms are no longer present. 19.00 (48.26) The alarm unit mounts in a standard 19-inch (48.3 cm) rack and NOTE: VALUES IN PARENTHESES ARE CENTIMETERS; ALL OTHERS ARE INCHES. occupies only 1 RU (1.75 inches or 4.45 cm) of rack space. For remote operation, the wiring from the alarm unit to the system controller should not exceed 4,000 feet (1,219 m). Daisy-chaining is required when more than 64 alarms are needed. Daisy-chain configurations can be used whether alarm units are situated locally, remotely, or as a combination of the two. The 64th input on an alarm unit can be used as an alarm output to report a data communication failure.
