ImproX (TRT) Twin Remote Terminal
INSTALLATION MANUAL
SPECIFICATIONS
Open Frame Construction (XRT910) and Aluminium Cabinet (XRT911)
Power Supply Combo (IPS920)
NOTE: The Power Supply Combo includes a 3 A Switch Mode Power Supply which
provides power for the (optional) internal unit and for charging the (optional)
backup Battery. As the Power Supply Combo needs no more than 1 A, you
may power extra devices using up to 2 A continuous current from the
provided connector block. DO NOT exceed this 2 A limit on continuous
c5(u)-3(rre)-4(9-4(t )-d)-3(rer)11w. Devices wit7.75 Tm a 7.75 Tmigh in

Figure 1: End-of-line (EOL) Sensing Circuit
NOTE: End-of-line (EOL) Sensing enables the Terminal to raise an alarm when
somebody tampers with the circuit (that is, cutting or shorting the wires)
between Input 1 (of DOS [1] or DOS [2]) and ‘ ’ GROUND (GND).
In other words the Terminal distinguishes between tampering on the circuit,
and the door being in an actual ‘Normally Open’ state.
By placing Resistors into the circuit between the Input 1 (of DOS [1] or DOS
[2]) and ‘ ’ GROUND (GND), the Terminal’s Digital Input monitors a
constant resistance through the circuit. When the circuit is tampered with,
the Resistors are bypassed; the Terminal detects the resistance change
raising an alarm.

NOTE: Because of the delicacy of the replacement procedure, we recommend you
contact your distributor before trying to replace the Power Supply Fuse.
Replacing the Battery Fuse
CAUTION: Ensure that you have disconnected the mains power supply to the
Power Supply Combo, and removed the Positive Lead from the
Battery before replacing the fuse.
