FUNCTION AND DESCRIPTION
AC Input. Connect the input terminals to a UL and/or
CSA listed Class 2 transformer. Use 18 AWG wire with
a maximum length of 50 feet.
Not used
Bell output, connect a bell or strobe to these terminals.
This output is limited to 500 mA ai 12.5 VDC. 1 amp for CSFM.
Siren output. 4 ohms max. connect a maximum of two 8 ohm (4 ohms), 10 W
min. speakers in parallel to these terminals. Use 18 AWG wire with a
maximum length of 50 feet. No external siren driver is necessary.
Negative. Earth Ground
Common. All common terminals are marked with a under the number.
Aux Power. This terminal provides 12.5 VDC. Maximum combined current of
Aux. power and Fire (terminal 11) is 330 mA using a 20VA transformer and
500 mA using a 25 VA transformer. May be used with any common.
Note: The red wire from the SCS is 12 VDC and must be connected to
terminal 8. The black wire from the SCS is common and may be connected to
any common terminal.
Keyboard Clock. This terminal provides the clock signal for the SCS and is
connected to the green wire on the SCS. Up to 4 SCS's may be connected in
parallel with cable length up to 300 feet. Using ordinary 4 conductor telephone
cable. Home run any SCS cables in excess of 50 feet. IMPORTANT: Do not
run the SCS or any detection loop wires alongside (within 4 inches) of the
siren, 16VAC or 110VAC lines.
Keyboard Data. This terminal provides the data signal for the SCS and
should be connected to the Yellow wire on the SCS.
Fire power. This terminal provides 12.5 VDC. See Aux. power limitations
above. This output is used to power 4- wire smoke detectors and is
momentarily turned off (reset) after an alarm and the unit disarmed
