Set the daytime prealarm percentage to Off or 50, 55, 60, 65, 70, 75, 80, or 90 percent. This is
the amount of smoke that indicates a prealarm event before an actual alarm event is
indicated. The percentage is based on the sensitivity level selected above. For example, if you
select normal sensitivity and select 50 percent for your prealarm, when smoke levels reach
50% of the normal smoke level required to initiate an alarm, a prealarm event will be indicated.
Set the nighttime prealarm percentage to Off or 50, 55, 60, 65, 70, 75, 80, or 90 percent. This is
the amount of smoke that indicates a prealarm event before an actual alarm event is
indicated. The percentage is based on the sensitivity level selected above. For example, if you
select normal sensitivity and select 50 percent for your prealarm, when smoke levels reach
50% of the normal smoke level required to initiate an alarm, a prealarm event will be indicated.
Set to the type of base (standard, relay, isolator, or sounder) being used with the detector.
Set base follow to:
Alarm: The base activates its relay when the detector goes into an alarm condition
Alarm verify: The base activates its relay when the detector goes into alarm or alarm
verification. The base will not restore until both events have been restored.
Alarm prealarm: The base activates its relay when the detector meets the prealarm condition
or goes into an alarm condition. The base will not restore until both events have been restored.
Verify: The base activates its relay only when the detector goes into alarm verification. The base
will not restore until the verification event restores, which can happen if the device goes into
alarm.
Prealarm: The base activates its relay when the detector goes into a prealarm condition. The
base will not restore until the prealarm event restores, which can happen if the device goes into
alarm. If you do not set a prealarm threshold, the base will never activate.
Base follow refers to how the detector base operates in an alarm condition initiated by the
detector. The bases that work with this option are the sounder base and relay base. For
example, if the detector has a prealarm setting, but base follow is set to alarm, the base's relay
won't activate until the detector goes into an alarm condition. It won't operate on the prealarm
condition.
Select the device type based on the type of device you are programming.
Note: All possible device types are listed below. Available device types are affected by
marketplace, so you may see device types listed here that are not available for the device you
are programming because of the marketplace you selected.
Note: To correlate device types with personality codes when programming Signature Series
devices, refer to Appendix E.
Photo detector
Smoke: For smoke detectors and contact devices. All activations are immediately considered as
alarms. Circuit cannot be restored until devices are restored to normal and the panel is reset.
Smoke verify: For smoke detectors and contact devices. Two-wire smoke detector activations
are verified (delayed and confirmed) before activating an alarm. Four-wire smoke detectors
and contact devices are not verified and immediately considered as alarms. Circuit cannot be
restored to normal and the panel is reset.
Ion detector
Smoke: For smoke detectors and contact devices. All activations are immediately considered as
alarms. Circuit cannot be restored until devices are restored to normal and the panel is reset.
Smoke verify: For smoke detectors and contact devices. Two-wire smoke detector activations
are verified (delayed and confirmed) before activating an alarm. Four-wire smoke detectors
and contact devices are not verified and immediately considered as alarms. Circuit cannot be
restored to normal and the panel is reset.
