•
Note: leave E-O-L resistors provided, on all unused circuits.
•
Detector loop current is suffi cient to ensure operation of one alarmed
detector per zone.
•
Supervisory current: 5mA (including End-of-Line Resistor)
G. Heat Detectors:
•
Detection circuits allow for installation of any number of listed or ap-
proved normally open thermal detectors.
H. Smoke Detectors:
•
Contact the Viking distributor for a list of compatible smoke detectors,
information concerning the maximum number of smoke detectors
allowed per zone, and standby power requirements for the smoke
detector used. Also, refer to appropriate Fire Protection Equipment
Approval Guides.
•
For supervised four-wire smoke detectors, connect the Power Su-
pervision Relay to the last detector base 24V screw terminals.
•
See ACCESSORIES.

•
Contact the Viking distributor for a list of compatible indicating appliances and releasing devices. Also, refer to Viking Technical
Data and appropriate Fire Protection Equipment Approval Guides.
J. Alarm Relay
•
Basic panel includes one non-silenceable Form-C dry alarm contact rated 2 amps at 30 VDC and 0.5 amps at 30 VAC (resis-
tive).
K. Trouble Relay
•
Basic panel includes one Form-C dry alarm contact rated 2 amps at 30 VDC and 0.5 amps at 30 VAC (resistive). Trouble relay
will silence when trouble condition is cleared.
L. Zone Relay Module
•
Model B-1 Panels include one Zone Relay Module (4XZM) providing dry Form-C contacts controlled by each of the four output
circuits plus one general alarm and one panel/fi eld-wiring trouble relay. See Table 2.
M. Power Outputs
•
Four-wire Smoke Detector Power (resettable): Up to 200 mA total (four-wire smoke detector power plus non-resettable power
combined) DC current available. Maximum ripple voltage: 10mV p/p.
•
Non-resettable Power: Up to 200 mA total (four-wire smoke detector power plus non-resettable power combined) DC current
available.
•
Maximum ripple voltage: 10mV p/p.
•
RMS Regulated Power: Total current available for external devices: 0.5 amp (subtracted from 2.25 A available to indicating ap-
pliance circuits) DC current available.
•
Maximum ripple voltage: 100mV p/p.
