Page 6: Intended Use
Gateway API User Guide Introduction EpiSensor’s ZPC Pulse Counter is intended to interface with sensor products which produce either a dry contact (relay), open collector, or an active voltage pulse output. The ZPC reports the data through the wireless sensor network to the Gateway. -
Page 7: Pulse Output Installation
Note: the single-channel pulse counter may use the same hardware as the dual channel version and so would also have a 4-pin terminal block. However, only the first channel (IN1) will be enabled on the ZPC-10/12 variants. Dry pulses are not polarity sensitive, but Open Collector and Active pulses are polarity sensitive. Take note of the positive and negative terminals for both inputs. -

Diagram showing a ZPC-10 with Input 1 configured for a dry pulse (DP) For Mains Powered Pulse Counters the selector options are: ● AP for Active Pulse Inputs ● DP for Dry Pulse Inputs, or Open Collector Inputs ● 0-10 for 0-10 Volt Sensors (not used on the ZPC product range) ●... -
Page 9: Dry Pulse
Dry Pulse A dry pulse can be thought of as a simple switch. Window alarm contacts or reed switches would be examples of such a connection. In this configuration, a small voltage is applied to the + terminal of the IN connector. A pulse is detected when this signal is connected to the negative (–) terminal of the IN connector. -
Page 10: Pulse Rate
Pulse Rate Depending on the version of ZPC you have, the maximum pulse rate that the ZPC can handle will vary. For mains powered versions (ZPC-20, ZPC-22) the maximum pulse rate is 40 pulses per second, or 40Hz. For battery powered versions, the limit is 4Hz. - Page 11 Sensors These data feeds show the number of pulses counted by the ZPC, wireless performance and battery health: Sensor ID Data Feed Description Unit Resolution Reporting Default Read/Write Pulse Count The total Pulse Count on Channel 1 pulses Read/Write of the Pulse Input Interval Pulse The total number of Pulses on pulses...

Page 13: Status Led
A node must be in “command mode” before users can interact with the product. To put the node in Command Mode, press and hold the “MODE” button for 2 seconds, then release. At this point, a battery powered node will switch the LED On Solid, while a mains powered node will flicker the LED and then switch the LED On Solid. -
Page 14: Alt Led
Check the power supply, and if the problem persists, contact EpiSensor support. Alt LED The Alt LED will flash when data is transmitted or received on the ZigBee wireless network. For mains powered nodes, it will always be active - but for battery powered nodes, it will only be active when in Command Mode. -
Page 15: Install Mode
Install Mode Issuing a press sequence on the Mode button of a powered node can enable either “Install Mode” or “Site Survey Mode” on that node. In this mode, the LED will flash at a rate that indicates the wireless signal strength (Link Quality Indicator) of that node, based on the following table: Flash Rate Flashes per Second... -
Page 16: Enclosure & Label Material
Mounting Instructions The ZPC-10/12 product range will have one or two cable glands at the bottom for the pulse inputs depending on the model. The ZPC-20/22 is housed in the same enclosure, but includes an additional gland and mains voltage input cable. -
Page 17: Tamper Evident Seals
The label material is gloss white PVC foil with permanent adhesive and gloss overlaminate. The following table lists the certification and safety symbols that appear on the certification labels of EpiSensor products. Please refer to it for a definition of each symbol. -
Page 18: Battery Life
Battery Life The following table estimates battery life for the ZPC-10/12 range. There are other environmental factors that this table does not take into account, and the calculations are made assuming the wireless node is not logging data for long periods of time, that the pulse frequency is low, and that the pulse duration is quite short. -
Page 19: Wireless Communications
Wireless Communications All EpiSensor products use IEEE 802.15.4 ZigBee Pro for wireless communications operating at 2.4GHz. This is a secure, scalable mesh networking communications protocol designed for transmitting small amounts of data reliably, and at low power levels. There are two types of nodes in the EpiSensor wireless mesh network: powered nodes and battery nodes. -
