BEFORE INSTALLING
This information is included as a quick reference installation guide. Refer to the control
panel installation manual for detailed system information. If the IST200 will be installed in
an existing operational system, inform the operator and local authority that the system will
be temporarily out of service. Disconnect power to the control panel before installing
the IST200.
GENERAL DESCRIPTION
The IST200 Translator Module is intended for use in analogue addressable systems in
conjunction with System Sensor 22051EISE and 2251EIS intrinsically safe smoke sensors.
The IST200 Translator serves as an interface between the control panel and up to 15 of the
above sensors. It must be used in conjunction with the Y72221 Galvanic Isolator Barrier.

MOUNTING IST200 DEVICES
The IST200 mounts directly to a 100mm square electrical box with a minimum depth of
54mm, such as the SMB500 as shown in Figure 1.

WIRING
Notes: All wiring must conform to applicable local codes and regulations.
The IST200 translator must be mounted in a suitable electrical box.
The capacitance and inductance or inductance/resistance (L/R) ratio of
the cable connected to the hazardous area between the B501AP power
terminals (1 and 2) must not exceed the values indicated in Table 1.
1. See Figure 2 for wiring details.
2. Loop wiring from control panel to the IST200 should be shielded, and the
shield connected to ground only at the control panel. Cable from the IST200
to the barrier can be shielded, but if so, the shield should not be connected
directly to ground, but either left floating or connected to the loop input cable
shield. Cable from the barrier to the sensors can be shielded but if so, the
shield must not be connected to ground.
3. Secure translator to SMB500 mounting box as shown in Figure 1.
