Fire Detection

MD1IO

1 input and 1 output FYRA line module

The MD1IO is a 1-input, 1-output module for FYRA addressable analog loops. Specifically, it features 1 balanced/unbalanced input for alarm and fault signaling (line open and line short), used to connect 1 sensor or other conventional device with NO output relay contacts to the detection loop, and 1 output to control devices such as acoustic warning devices, optical-acoustic warning devices, or other devices. The output can be programmed in relay mode or to control an optical-acoustic warning device with line supervision. The module integrates an on-board line isolator and 2 two-color LEDs that provide information about the input/output and communication status. Programming the identification address is immediate and is performed via a rotary switch, while programming the functions is done via dipswitches. The small-sized plastic container is also suitable for installation in flush-mounted boxes, including type 503. The MD1IO module is certified CPR 305/2011 EN 54‑17 and EN 54‑18
