I/O Expander Module (EL-4770)

The 2-Way Wireless I/O Expander Module (EL-4770) is an extension module enabling wired devices to be connected to
the iConnect Control System (SW versions 305 and above). The iConnect
Wireless I/O Expander Modules. Each 2-Way Wireless I/O Module supports 8 hardwired zone inputs, 2 auxiliary outputs
and has the capability to control up to 2 PGM devices. Each output or PGM device can be operated in a response to a
wide variety of system events.
The 2- Way Wireless I/O Expander Module is installed outside the Control System in its own dedicated plastic unit
equipped with case open and wall removal tamper protection. The Wireless I/O Module is also provided with its own
power supply and backup battery.

Box & Wall Tamper
Box and wall tamper switches provides extra protection. If the plastic unit is opened the front tamper switch is released
and an alarm is generated. In the event that the plastic unit is removed from the wall, the screw causes the perforated
section of the plastic and attached tamper mechanism metal plate to break and remain attached to the wall. As a result,
the back tamper switch is released and an alarm is generated.
The front tamper switch is located on the front of the circuit board and is depressed via a spring when the front plastic
cover is closed. The back tamper switch is located on the rear side of the back panel and is constantly depressed.
