MS-I8S PROCESSOR
Installation and Specifications:
1. General:
The MS-I8S is part of Mercury Security's bridging hardware technology for replacing the Software House
I8-CSI module that provides sensor monitoring when migrating to the Mercury platform.
Mercury's MS-I8S board has eight inputs, which may be configured to support unsupervised or
supervised alarm input circuits. In addition, one dedicated input is provided for cabinet tamper switch
monitoring. The MS-I8S requires 12 Vdc for power.
2. Supplying Power to the MS-I8S:
The MS-I8S requires 12 Vdc for power.
TB9 pin 1: Ground
TB9 pin 4: +12 VDC
Locate power source as close to the unit as possible. Connect power with minimum
of 18 AWG wires.
Observe POLARITY!

3. Communication Wiring:
The MS-I8S communicates to the MS-ICS intelligent controller via a 2-wire RS-485 interface. The
interface allows multi-drop communication on a single bus of up to 4,000 feet (1,200 m). Shielded cable
of 24 AWG with characteristic impedance of 120 ohm is specified for the RS-485 interface.
The last devices on each end of the cable should have the terminator installed (install jumper J1).
4. Alarm Inputs Wiring:
Input circuits can be configured as unsupervised or supervised. When unsupervised, reporting consists
of only the open or closed states.
When an input circuit is configured for supervision, then the MS-I8S board also monitors the following
abnormal circuit conditions: open circuit, shorted circuit, the grounding of either side of the circuit*, or the
introduction of a foreign voltage*. A supervised input circuit requires adding two resistors to the circuit to
facilitate proper reporting. The standard supervised circuit requires 1k Ohm, 1 % resistors and should be
located as close to the sensor as possible. Custom end of line (EOL) resistances may be configured via
the host software.
* Grounded and foreign voltage states are not UL 294 required and therefore not verified by UL.
The input circuit wiring configurations shown are supported, but may not be typical:
5. Cabinet Tamper Switch Input Wiring:
Connect TB10 terminals to the cabinet tamper switch. The cabinet tamper switch must
be a normally closed contact. Do not use EOL resistor(s). Install a jumper wire to these
terminals if a cabinet tamper switch is not used.
