I-Spy Mini Switch Monitor Module and
I-Spy Mini Priority Switch Monitor Module
Installation Instructions
General
The I-Spy Mini Switch Monitor Module, part no IS816, is a loop-powered device, which
incorporates a monitored input circuit for connection to switches. The module is supplied as
a small plastic housing designed to fit into an electrical box. Six flying leads of 18AWG are
used to connect the module.
A red LED flashes in synchronization with the current pulse reply from the device. If output
bit 2 is set the LED is illuminated continuously.
The I-Spy Mini Priority Switch Monitor Module, part no IS815, has, in additon, a priority
interrupt facility to give fast response and can be fitted in an electrical box behind a pull
station.
Note: the I-Spy Mini Switch Monitor Module and the Mini Priority Switch Monitor Module are
not designed for outdoor use unless they are mounted in a suitable weatherproof enclosure.
Installation
1. The I-Spy Mini Switch Monitor Module and the I-Spy Mini Priority Switch Monitor Module
are not physically attached to the electrical box other than by means of the flying leads.
2. Connect the modules for Class A wiring or Class B wiring (Fig 2). Bit 8 of the DIL
switch is used to select the class of wiring. All wiring must conform to local codes and
regulations.
