The Kentec K03000M2 is the Sigma XT Ancillary PCB supplied boxed in an M2 size steel enclosure, for 24V DC operation. The Sigma XT Ancillary Board is compatible with Sigma XT control panels running operating software version SIGXT_11A.HEX or above, and Kentec lists it (K588) as the ancillary relay board for Syncro XT+ panels. It provides volt-free, normally open contacts so that sub-systems and plant can be controlled remotely from the main panel over a two-wire data bus.
As a 24V DC version it needs a two-core data cable from the main control panel plus two further cores for power, taken either from the main panel or from another 24V DC source.
Key features
- Two-wire RS485 serial connection to the control panel
- Up to 7 ancillary boards per control panel, each addressed 1 to 7 on a binary-coded DIL switch
- Status units and ancillary boards can be mixed on the same serial data bus (up to 7 of each type)
- Volt-free relay outputs for fire and extinguishing system status
- Relay-operated LED indicators
- Total data cable length from the main panel to the last unit must not exceed 1200 metres
