5.6 Appendix 6 – Hochiki ESP Information
At power up the panel allows a couple of minutes for Hochiki ESP detectors to stabilise. Any detectors that the
panel knows to be present will then be calibrated. The panel displays can be used normally during this time, but
the fire detection response will be slower until all the calibration phases are complete. If devices are inspected
during this period, they may show their state as: -
“Reset” - panel has reset the device at power up, resetting from a fire etc.
“Calibrating” - checking ESP “Zero Point” and “Fire Points”
“Initialising” - loading detection thresholds, sounder volumes etc.
Calibration can be manually initiated any time at access level 3, forcing all the devices on the selected loop to
be calibrated. Transferring new device information from a PC to the panel will also cause the effected devices to
be re-calibrated.
Periodic re-calibration can be performed at levels 1 & 2 under control of one of the 7-day time clocks. The time
clock settings are configured from PC program.
5.6.1 Unprocessed Analogue information
For most purposes the “Value” field in the View/Edit menu gives the easiest to read and the most useful
information from a detector as it is scaled and displayed in standard engineering units. It is, however, possible to
see the unprocessed analogue signal (AN) by moving to the Additional Info field.

5.6.2 CHQ-BS / CHQ-WS Sounders
Unlike standard sounders, these loop-driven sounders can be programmed to give out many different tones and
be individually programmed to adjust the sound output. When programmed from the panel they will default to
turn on at 85dB. Use one of the many tones available from the PC instead of the standard “Pulse” option if any
special ringing is required.
The panel utilises the “group” features of the CHQ-BS/WS, so that when a command is sent to turn one device
on, all other CHQ-BS/WS devices within the same group will turn on at virtually the same time from the same
command (and likewise when they are silenced). Allocate unique “Output Groups” to CHQ-BS/WS devices,
with no other device types using that group.
