Connect EOL device (1.3K, 1/2W resistor) to terminals 3 and 4 of
TB1 when no external detectors are connected.

When the relay cont
act
s are connected to a fire alarm system, the
trouble cont
act
s must be wired beyond the last detector so as not
to interfere with an alarm, as shown in Figure 7.

relay for alarm signaling. Do not connect relay
modules directly to detectors.
