No se si migraste o podrías migrar a FB >= 2.

En esta versión existe la clausula LOCK TIMEOUT.

Lock Timeout for WAIT Transactions
A. Karyakin, D. Yemanov
All Firebird versions provide two transaction wait modes: NO WAIT and WAIT. NO WAIT mode means that
lock conflicts and deadlocks are reported immediately, while WAIT performs a blocking wait which times out
only when the conflicting concurrent transaction ends by being committed or rolled back.
The new feature extends the WAIT mode by making provision to set a finite time interval to wait for the concurrent
transactions. If the timeout has passed, an error (isc_lock_timeout) is reported.
Timeout intervals are specified per transaction, using the new TPB constant isc_tpb_lock_timeout in the API or,
in DSQL, the LOCK TIMEOUT <value> clause of the SET TRANSACTION statement.

Note
The DSQL equivalent is implemented via the LOCK TIMEOUT <value> clause of the SET TRANSACTION

Un ejemplo:

SET TRANSACTION WAIT SNAPSHOT NO AUTO UNDO LOCK TIMEOUT 10
