Intelligent Single Input / Output Module

The Intelligent addressable input/output module. A single volt free relay with N/O and N/C change over contacts that can be driven via the fire alarm loop. Commonly used for overriding equipment such as AHU’s, Smoke extracts, Lift returns, auto dialer, BMS, etc. The input can be linked through a volt free contact switch output of ancillary equipment reporting to the fire alarm controller. According to the pre-inputted cause and effects interface programming, the alarm controller sends out a start command to the equipment required to start. After receiving the command, the module activates its relay to change state. Once the equipment under control has operated a confirmation signal can be sent back to the fire alarm controller. Electronic addressing can be done through Handheld Programming tool (P-9910B), purchased separately.
