Embedded Mode - Honeywell H-S81-HS Manual

SB-ECM Module
functions ensure a local level of risk protection, even when communication with the panel is inter-
rupted. In backup mode, output control is transferred to the module's internal logic functions. When
the module detects that communication with the panel has been reset, output control is taken by the
panel, unless the internal logic phase is in progress. The internal logic sequence cannot be inter-
rupted until it has been completed. Once the internal logic sequence is completed, the module will
send a reset request message to the panel. At this point, the operator cycle must reset the stand-
alone mode in order to hand control of the outputs back over to the panel. The panel signal reset
will occur automatically only after receiving a confirmation message from the module concerned.
NOTE: The SB-ECM module goes into backup mode in the following cases:
- no communication with the control board for 1 minute
- no communication with the control board at power-up for 2 minutes
- no communication between the control board and the panel for 5 minutes (fail-safe)
NOTE: After having programmed the address using the SB-PRG programmer, the embedded
logic is set to type-0 (no internal logic). This is why if at first startup a module does not connect to
the panel, after two minutes it will not execute an internal logic.

Embedded Mode

In this operating mode, output control is always carried out by the module itself according to the
type of logic set during programming. This occurs whether or not there is communication with the
panel. However, it is possible to command the module outputs from the panel using a diagnostic
cycle or a supervision system command, while it is not possible to command the outputs from local
or remote rules. In any case, the panel will still display signals regarding the state of the module
inputs and outputs. Furthermore, the individual module channels can be disabled from the panel. If
a channel is disabled, the programmed logics for that channel will not be executed. The following
types of embedded logic are available:
Type-0 No logic (applies only to I/O Mode)
Type-1 Standard extinguishing logic with one group of cylinders or one solenoid valve
Type-2 Main/Reserve extinguishing logic
Type-3 Main/Reserve Discharge extinguishing logic
In embedded mode, the first 10 channels and channel 15 carry out a fixed function that depends on
the type of embedded logic configured, while channels 11, 12, 13, and 14 can carry out EV, TOA or
TO functions depending on the type chosen during programming. During configuration, the follow-
ing parameters are set for each SB-ECM module:
• Reset inhibition time (0-30 minutes in UL Mode)
• Manual discharge delay (0-30 seconds in UL Mode)
• Automatic discharge delay (0-60 seconds)
• Hold mode (Mode A-B-C)
• Manual discharge mode (n-DO, y-DO)
The input and output operating modes depend on how they are programmed. The following table
contains the operating modes that must be set during programming in order to comply with EN
12094 standards.
Note: Refer to the S81-HS UL Listing Document (ST-061-EN) for UL 864 compliant programming
options.
