range for that value. Take note of the range of values allowed (in
brackets) and try again.
Bad detector :
A detector address has been entered which is either outside the
allowed range or which is not present on the loop. This may also
happen if the user has entered address 000 (command module) for a
function which it does not support (for example, alarm factor).

The Command Module has unsuccessfully attempted to read a
function value from a connected unit. Check that the unit connected
supports this function.

There is a break in the communications loop between the detector
addresses specified. Check the wiring.
Comms fault
The Command Module has polled a detector and no response has
been received after the specified poll timeout value. See section
185619544.01.1.1 “Poll Timeout (Numeric - CM only)” on page 24
Bad access code An incorrect access code has been entered. Enter the correct code.
Battery fault
This indicates either that the standby battery has discharged to a
predetermined level or that no standby battery is fitted. In the former
case, the battery should be replaced and recharged. In the latter
case, the battery check should be disabled (see section
185619544.01.1.1 “Battery Check Enable (Yes/No - Address 000-
127)” on page 21). It is important that the battery fault be acted upon
as soon as noticed, as excessive discharge may cause damage to
the battery. The battery fault condition comes on before the battery
reaches this portion of the discharge curve.
Watchdog reset
This indicates that there has been a power supply fault. If there are
frequent power outages it may be advisable to power the unit from a
UPS.
Detector fault
This indicates that there is a problem with the detector head. This
may be due to a number of causes. Refer to the chart readout if this
can be downloaded to a PC and note the detector signal level at the
time of the fault. When as much information as possible has been
determined about the conditions at the time of the error, please
contact the Hochiki Europe (UK) Limited Product Support Department
(see page 2).
