Device type Description
Heat alarm RoR For heat detectors with rate-of-rise. All activations are immediately
considered as alarms. Detectors cannot be restored until the
condition causing the activation clears and the panel is reset.
Photoelectric smoke detectors (PS)
Smoke For smoke detectors and contact devices. All activations are
immediately considered as alarms. The panel and detector cannot be
restored to normal until the smoke condition has cleared and the
control panel is reset.
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. The panel and
detector cannot be restored to normal until the smoke condition has
cleared 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 smoke condition has
cleared. Resetting the control panel is not required.
Note: Available device types depend on the position of the slide switch on the front of the
module. For example, if the slide switch is in the alarm position, only alarm device types are
available.

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.
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.
