Wiring Recommendations for Loop Card Modules
(SCM-LCM)
The SCM-
LCM’s
are rated for 450mA each, but it is recommended that you leave an allowance ~100mA for any future loop expansion.

MKII-AOP
MKII-AOP
- The Fyreye MKII optical smoke detector (MKII-AOP) uses a pulsing IR LED &
photodiode to detect IR scatter caused by smoke entering the chamber.
The detector is particularly suitable for detecting optically dense smoke, involving
materials such as soft furnishings, PVC, plastic, foam and all similar materials which
produce small visible particles (0.5 to 10μm).
MKII-AHR, MKII-AHFand MKII-AHF/CS90
MKII-AHR, MKII-AHF and MKII-AHF/CS90
- The Fyreye MKII Rate of Rise heat detector
(MKII-AHR) uses a thermistor arrangement to sense a quick rise in temperature and also a
final threshold temperature of 57°C. The Fyreye fixed heat detector (MKII-AHF) has a
single thermistor arrangement that gives an alarm at a temperature of 57°C, where the
MKII-AHF/ CS90 give an alarm above 86°C.
MKII-AOH
NOTE:
• Line capacitance shall not exceed 0.1µf (100nF)
• Inductance shall not exceed 1mH
• Resistance shall not exceed 50 Ohms.
RECOMMENDED CABLE:
The general recommendation would be to use a standard fire resistant cable, such as
Firetuf
™, FP200 or
an equivalent, 1.0mm
2
to 2.5mm
2
. These cables are screened, and will provide good EMC
shielding when properly grounded at the panel.
