MRI-4010
Is a Secutron photoelectric smoke detector that provides early fire warning by constantly monitoring the environment. It is part of an addressable fire alarm system and features configurable sensitivity settings, advanced software to reduce false alarms, and a unique anti-tamper feature. The device uses different LED colors to indicate alarm and fault conditions. A variation, the MRI-4010-ISO, includes a built-in short-circuit isolator for enhanced loop performance.
MRI-4020
Is a hardwired, multi-sensor detector from Secutron used for early fire detection. It continuously monitors the environment for fire conditions by combining smoke and heat sensing technologies. The "ISO" version (MRI-4020-ISO) includes an isolator to protect the system from wiring faults and loop failure.
MRI-4030
Is a tri-mode heat detector from Secutron/Mircom Technologies that provides early fire warning by monitoring ambient temperature. It operates in one of three modes: fixed temperature at either \(135^{\circ }F\) (\(57^{\circ }C\)) or \(175^{\circ }F\) (\(79^{\circ }C\)), or rate-of-rise detection, and communicates with a compatible fire alarm control panel. The detector is part of the MRI-4000 series, which can support up to 240 devices on a single Signaling Line Circuit (SLC) and uses tri-color LEDs for status indication.
MRI-4040
Is a dual input module used for alarm, supervisory, or monitor applications in compatible fire alarm control units. It provides two independent contact monitoring circuits, which can be configured as one Class A or two Class B inputs, all using a single address on the SLC loop. Key features include an internal EOL resistor for Class A configuration, a panel-controlled LED indicator, and a unique address set using a programmer tool.
MRI-4041
Is an intelligent, addressable mini dual-input monitor module for use with compatible fire alarm control units. It connects to a Signaling Line Circuit (SLC) loop and provides two independent contact monitoring circuits, allowing it to monitor two Class B inputs or one Class A input, all while using a single address. It features an LED indicator for status and is designed to fit in a standard single-gang junction box.
MRI-4042
Is a conventional zone module that connects a zone of traditional fire alarm devices to an intelligent, addressable loop in a fire alarm system. It allows for the modernization of existing systems by integrating conventional detectors into an addressable panel and can be configured to work with two-wire devices or 4-20mA devices. The module monitors the current used by connected devices and reports alarms and troubles to the control panel.
MRI-4045
Is an intelligent, addressable module for fire alarm systems that controls and monitors two independent circuits using a single module address. It provides two form C (SPDT) relay contacts and is designed to respond to alarms and other inputs from a compatible Fire Alarm Control Unit (FACU). The MRI-4045-M is a related model with eight relays.
MRI-4046
Is a Secutron 4000 Series Supervised Output Module used with compatible fire alarm control panels to manage a variety of functions, such as controlling notification appliances (lights, horns), speaker circuits for voice evacuation, and fire phone systems. It is an addressable intelligent module that can be configured for specific applications and supports both Class A and Class B wiring.
MRM-710MPU
Is a Secutron fire alarm manual pull station that is dual-action, key-resettable, and has a permanently attached intelligent addressable module for fire reporting. It is constructed from die-cast metal and has a red enamel finish, is designed to meet the ADA 5-lb manual force requirement, and uses the MP protocol for communication
MS-401U
is a durable, red, aluminum manual fire alarm pull station for initiating a fire alarm signal. It is a non-coded, single-action device designed for commercial, industrial, or residential buildings, and it can be easily reset with a 1/8” screwdriver. The handle remains in the "pulled" position until manually reset, and it can also be converted to a double-action station with an additional lever.
