Alarm PCB
Active alarm inputs vary by DVMRe model. 4 channel units (4CT) have 4 active alarm inputs. 10 channel units (10CT) have 10 active alarm inputs.
Alarm Input
An alarm condition can be activated by devices such as pressure pads, passive infrared detectors, door switches, or other similar devices.
See section 3.11 for information about configuring the contacts as Normally Open or Normally Closed in the menu system.
Normally Open, Zero Potential Relay Contact: Configure in menu as Normally Open.
Normally Closed, Zero Potential Relay Contact: Configure in menu as Normally Closed
TTL Active High: Configure in menu as Normally Closed. | High: 5V (12V Tolerant) |
TTL Active Low: Configure in menu as Normally Open. | Low: Ground |
Open Collector Active On: Configure in menu as Normally Open. | Inputs: 1 per channel. |
Open Collector Active Off: Configure in menu as Normally Closed. |
