End-of-Line Resistor for Style Y circuit: Model R-20K, ½ watt P/N 75477.
Master CMD Out - TB6 Terminals 1(-) & 2(+)
Provides trigger for additional units. Will drive MR-101C or MR-201C relays (manufactured by Air Products and
Controls) to provide alarm relay contacts.
Supervised and power-limited circuitry
Operation: Output reverses polarity on activation of Manual Evacuate switch or when either CMD1 or CMD2 are
activated (in alarm)
Normal Operating Voltage: 24 VDC regulated, filtered. Reverse Polarity Current: 60 mA maximum.
Standby Voltage: -5 VDC. Short Circuit Current: 0.5 mA.
Specific Application Power - TB4 Terminals 1(-) & 2(+)
Up to 35 mA @ 24 VDC is available for powering control modules and associated End-of-Line power supervision
relays.
Power-limited circuitry. Refer to Appendix D for compatible devices.

Controls and Indicators
Front Panel Switches:
•
Two Position Toggle Switch:
✓
MANUAL EVACUATE - up position (latching)
✓
MESSAGE OVERRIDE (microphone paging) - down
position (momentary)
•
TROUBLE SILENCE (REC) - momentary depression silences
the local piezo when system is in trouble condition. Switch is also
used for recording customized messages. See “S1 DIP Switch
Settings” on page 15 and “S5 DIP Switch Settings” on page 16 for
additional information on recording messages.
•
MESSAGE PLAYBACK - for reviewing recorded message
(requires optional FC-LPS module).
