TC12 Installation, Commissioning & Maintenance Handbook

3.3.3.78 High Occupancy, timed zero occupancy (GHZ)

GHZ = {time in seconds: 0-255} (8)

Comment: Zero occupancy will be assumed after the pre-set time.

3.3.3.79 High Occupancy, smoothed occupancy high value (GHV)

GHV = {percentage smoothed occupancy high level: 0-100} (90)

Comment: Smoothed occupancy high value used for alarm detection.

3.3.3.80 High Occupancy, loop input allocation (GHL)

GHL = {Hi-Occ Unit: 0-7} = {input bit: 0-31} (255)

Comment:

HIOCC loop input allocation, assigns an input bit (0-31) for each

HIOCC unit (or 255 to indicate that the unit is not configured).

3.3.3.81 High Occupancy, number of consecutive samples (GHN)

GHN {loop no. 0 to 7} = {1 to 10}. (3)

Comment:

The number of consecutive occupancy samples used to determine

if an alarm condition exists.

3.3.3.82 High

Occupancy,

smoothing factor (GHF)

GHF = {Smoothing factor: 0-100} (2).

Comment:

The smoothing factor used in calculating the new smoothed

occupancy. This value represents actual smoothing factors of 0 to
1, i.e. the default value of 2 represents 0.02 for calculation
purposes.

3.3.3.83 High

Occupancy,

clearance threshold (GHC)

GHC = {clearance threshold: 0 to 100} (70).

Comment:

The fixed clearance threshold is used to determine an alarm

clearance condition in the event that the smoothed occupancy
average is at an abnormal level prior to an alarm.

Remote Handset Commands

3.3.3.84 Open link to controller

XXC {Opens Link to Controller}

Comment:

If the OTU is connected via a cable to the controller handset port,

inputting XXC <CR> opens the link. Note that there will be a delay
after initiating this command and the user should wait for about five
seconds before attempting to enter controller handset commands.

3.3.3.85 Close link to controller

XXO {Returns Link to OTU}

Comment:

Closes controller link and returns control to the OTU.
