Full Specifications Of The Trap Relay

Trap Relay 64 Back Panel
The Trap Relay 64 provides you with 64 control relays and can process inbound SNMP trap information to operate these web-based relays.

The Trap Relay provides a cost-effective and critical way to link inbound SNMP traps with a relay output. This device is the first of its kind from DPS. Typically, SNMP traps are forwarded from an RTU to an SNMP Manager.

This device will receive inbound SNMP traps and use this information to operate or release one of the device's controls relays. Traps received by the Trap Relay can be identified by either IP address, Trap ID, or by an additional variable binding.

In other words, the Trap Relay mediates contact closures (equipment alarms, doors, motion, water leaks...) and analog inputs (generator voltage, fuel gauge reading...) to SNMP traps.

So, whether you have a fire alarm control panel or any other piece of gear at your remote locations that only takes in contact closures, the Trap Relay device will fix this gap and translate SNMP to contact closures.

With the 64 relays, you'll be able to remotely control any device that you normally operate with a button or a switch. The relays will latch or release a contact closure based on the commands it receives. Relays are perfect for turning on small devices, opening doors, interfacing with legacy alarm systems, operating visual/audible notification systems, and rebooting jammed equipment.

The Trap Relay RTUs can be operated in one of two modes:

  1. Granular mode

    Allows the user to configure each relay to operate or release based on the enterprise, generic-trap, and specific-trap information of an SNMP v1 trap or the trap OID of an SNMP v2c trap.

  2. Cisco-VMS mode

    The unit will ignore each relay's SNMP trap configuration and will momentarily operate relays when it receivers either one of several VMS 6.3 SNMP Traps. A relay in Cisco-VMS mode will only operate if its description matches the VMS trap's mediaStreamName value.

If you have a specific device you want the Trap Relay to interface with, contact the engineers at DPS to have a specific model created just for you.
