Note Regarding Default Configuration
i
Note
By default, the TSA-1000 is programmed for all input zones are detectors
zones and all outputs are general outputs.
To modify these and additional settings, the TSA-1000 must be programmed
accordingly.
3.6
Maximum Number of Detectors
EN 54-2 specifies a limit of 32 detectors per zone, which is the limit of each zone of the
TSA-1000; hence the TSA-1000 max number of detectors is dependant on the
configuration, and the number of zones.

Suitability of use in various environments
See

3.7.1 Environmental Limits and Protection Level
The TSA-1000 environmental limits are specified in EN-54-02:1998 para. 12.
The TSA-1000 is specified for -5°C to +40°C, RH max 95% temperature range, and
IP30 protection level.

for
information about maintaining the protection level.

Note
Do not operate the ECD outside the specified limits.
3.7.2 Suitable Environment
The TSA-1000 environmental limits are stated above. It is to be installed in an indoors
location, well ventilated location, protected from the elements.
Avoid locating the CP in direct sunlight or near sources of heat.
It is recommended to install the CP in an electrically quiet location (i.e. away from high
power cables, motors, etc).
3.8
Limiting the Consequences of Faults
See
POWER SUPPLY, CHARGER AND BATTERIES
, page 22, for explanation of
PS/Charger limiting/protection devices.
The Main Board, which contains the charging circuitry and the battery protective
resettable PTC, also has a common electronic limiter for most output ports (It does not
protect the contacts of relays!), which are monitored by the CPU
If there is an overload on an output (or outputs), the common limiter shuts off, the buzzer
sounds and the visual fault indication and the Fault relay are switches ON. The CPU
switches OFF all the controlled outputs. It then switches ON the separate outputs in
