E-FSA64 and E-FSA250 Technical Reference Manual

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.

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.

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.
