Device type Description
Smoke verified 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 until
devices are restored to normal and the panel is reset.
Supervisory latching For detectors that trigger an active (supervisory) event.
Detectors with this device type remain active until the condition that
activated them is restored and the control panel is reset.
Supervisory nonlatching For detectors that trigger an active (supervisory) event.
Detectors with this device type remain active until the condition that
activated them is restored. Resetting the control panel is not required.
Duct detectors
Duct alarm For duct smoke detectors. All activations are immediately considered as
alarms. Circuit cannot be restored until devices are restored to normal
and the panel is reset.
Duct supervisory (latching
and nonlatching)
For duct supervisory devices. Momentary activation of normally open
devices immediately places the panel in a supervisory state and turns on
supervisory LEDs and relays. Circuit cannot be restored until devices are
restored to normal and the panel is reset.
Heat detectors
Heat alarm For heat 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.
Heat alarm RoR For heat detectors and contact devices with rate-of-rise. All activations
are immediately considered as alarms. Circuit cannot be restored until
devices are restored to normal and the panel is reset.

Device type Description
2Wire Class A Allows for the monitoring of two-wire conventional smoke detectors in a
Class A circuit (that do not require alarm verification) and normally open
contact initiating devices on the same circuit.
2Wire Class B Allows for the monitoring of two-wire conventional smoke detectors in a
Class B circuit (that do not require alarm verification) and normally open
contact initiating devices on the same circuit
2Wire verify Class A Allows for the monitoring of two-wire conventional smoke detectors in a
Class A circuit (that require alarm verification)
2Wire verify Class B Allows for the monitoring of two-wire conventional smoke detectors in a
Class B circuit (that require alarm verification)
Alarm 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.
