Product Overview
In each state, the detector activates different outputs, as specified in
Table 7.

1 The alarm outputs are activated while alarm conditions exist and will stop approximately 5 seconds
after the fire is no longer detected.
2 The alarm state can be optionally latched via programmed function (default is non-latched).
3 The detector will remain in BIT Fault state until it has passed a successful BIT.
4 The auxiliary relay can be activated at the warning level or alarm level, depending on programmed
function.
Note:
The outputs depend on the wiring options.
2.5.6.1 Optional Latching
Alarms are set as non-latching by default. However, the detector includes a
latched alarm output capability, which operates according to the programmed
function.
If selected, upon detection of a fire, the detection signal is latched until a manual
reset is performed (disconnecting the power supply, or performing a manual BIT
(see
Manual BIT on page 30).
Latching affects the alarm relay, 0 – 20mA output, the alarm LED (the auxiliary
relay will be latched only when the programmable function auxiliary relay is set
to yes.
