Update Rate: 41 ms following alarm state; 1 ms for alarm state clear.
Sequences: Input follower, ISA Sequences A, F1A, F2A, F3A, M, F1M, 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 push button), -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 3A @ 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 Ω, 250 VAC (PDX6901).
Relay Operation: Relay 1: Alarm state until alarm is acknowledged. Relay 2: Alarm state if 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.

ATEX/IECEx Specific Conditions of Use:- The equipment label and epoxy coating may
generate an ignition-capable level of electrostatic
charges under certain extreme conditions. The
user should ensure that the equipment is not
installed in a location where it may be subjected
to external conditions (such as high-pressure
steam) which might cause a build-up of
electrostatic charges on non-conducting
surfaces. Additionally, cleaning of the equipment
should be done only with a damp cloth.
- Flameproof joints are not intended to be repaired.
- All entry closure devices shall be suitably certified
as “Ex d”, “Ex t” and “IP66/68” as applicable.
Suitable thread sealing compound (non-setting,
non-insulating, non-corrosive, not solvent based,
suitable for the ambient rating) must be used at
the NPT conduit entries to achieve the IPx8
rating while maintaining the Ex protection
concept.
Year of ConstructionThis information is contained within the serial number
with the first four digits representing the year and

For European Community:The ProtEX-MAX must
be installed in accordance with the ATEX directive
2014/34/EU, and the product certificate Sira
