Analog Signal
Analog signal (4 ‐ 20 mA)
Signal level Detector State
(±0.1) mA Circuit opening
(2 ± 0.1) mA Fault
(4 ± 0.1) mA Normal
(18 ± 0.1) mA Fire
(2 ± 0.1) mA Test
Digital Signal Informational digital signals are standard RS ‐ 485 communication with Modbus:

Hardware self ‐ test Fault

Optical interference Fault

Fire detected
(The digital channel protocol Modbus RTU is described in Appendix B.)
Relay Dry Contact
Signal
Relay dry contact signal:

Operation of the normally open Fire relay dry contacts *
o
FIRE relay – two ‐ directional single ‐ pole contact, which allows the state to be
changed at the output to normally closed or normally open by using the ESP
Commander program. The contact relay is rated for currents ranging from 10 mA
to 5 A at DC voltage of 30 V.
The output signal “Fire” can be cleared after eliminating the source of the alarm
signal.
* A normally closed condition of the Fire relay contacts does not comply with the
requirements of NFPA 72 or ULC/ORD – C386 and is not approved by FM approvals.

Operation of the normally open Fault relay dry contacts
o
FAULT relay – single ‐ direction pole contact which is normally open. The relay is
designed to handle currents of 10 mA to 5 A at DC voltage of 30 V.
Refer to Table 4 ‐ 1: Determining LED Conditions above.
Operating Modes Possible detector configurations using ESP Commander
The IPES–IR/UV has the following detector operating modes:

“Near/far” and “slow/fast” modes – To provide maximum sensitivity.

“Latching/non ‐ latching mode”– To select either latching or non ‐ latching functionality of
the fire relay, which provides latching alarm state for the fire ‐ alarm relay in compliance
with NFPA 72 and ULC/ORD – C386.
The manufacturer’s default settings correspond to far and fast. To change the manufacturer’s
settings connect the flame detector to the computer and use the ESP Commander program.
