Inputs
INPUT TYPES
NO or NC switches: No external excitation required
Open collector transistor (NPN):
Open circuit voltage approximately 3.3 VDC
Logic Levels: LOW = 0 to 0.9 VDC
HIGH = 2.4 to 28 VDC
UPDATE RATE
41 ms following alarm state; 1 ms for alarm state clear
SEQUENCES
Input follower, ISA Sequences A, F1A, F2A, F3A, M, F1M,
F2M and F3M per ISA Standard ISA-18.1-1979 R2004.
SEQUENCE
OPTIONS
A, F1A, F2A, F3A, M, F1M, F2M, and input follower with
selectable options -1 (silence pushbutton), -4 (no lock-in),
and -6 (no horn) per ISA Standard ISA-18.1-1979 R2004.
Relays
RATING
2 SPDT (Form C); rated 3 A @ 30 VDC or 3 A @ 250 VAC
resistive load; 1/14 HP @ 125/250 VAC for inductive loads
ELECTRICAL
NOISE
SUPPRESSION
A suppressor (snubber) should be connected to each relay
contact switching inductive loads to prevent
disruption to the microprocessor’s operation.
Recommended suppressor value: 0.01 µF/470
, 250 VAC
(PDX6901).
RELAY
OPERATION
Relay 1: Alarm state until alarm is acknowledged.
Relay 2: Alarm state while any channel indicating alarm
condition.
FAIL-SAFE
OPERATION
Programmable
Independent for each relay
Note:
In fail-safe mode, relay coil is energized in non-alarm
condition. In case of power failure, relay will go to alarm
state.
