SMS SenTRI Single 1.5A Mains Rated Output Module
£466.14 (inc VAT: £559.37)
Summary
The SMS 78302-02NM is a sophisticated mains powered interface unit designed for use with the SMS SenTRI range of fire alarm control panels. This EN54-4 compliant, battery-backed power supply unit connects directly to the SenTRI loop whilst providing highly flexible interfacing capability for connecting to ancillary units that cannot be integrated directly onto the SenTRI loop.
The unit offers superior functionality and provides a powerful solution to meet the fundamental requirements of applications requiring compliance to BS7273 part 4, the code of practice governing door holders and door release mechanisms. Additionally, the 78302-02NM offers a practical and cost-effective solution for Intrinsically Safe applications, with intrinsically safe devices able to connect directly into the isolation barriers housed within the unit.
Supplied complete with 2 x 12V 2.1Ah standby batteries in a robust metal enclosure, this mains powered interface reduces installation and maintenance costs by including all elements within a single unit. The configurable auxiliary powered output is derived from its self-contained EN54 part 4 compliant mains powered supply unit, ensuring reliable operation even during mains supply failure.

FAQs
What is BS7273 part 4 compliance and why is it important?
BS7273 part 4 2007 is the code of practice governing door holders and door release mechanisms. The 78302-02NM offers compliant solutions where interface outputs can be configured as both Category A or B door release outputs, ensuring fire safety door control systems meet regulatory requirements.
How does the unit support Intrinsically Safe applications?
Intrinsically safe devices can be connected directly into the isolation barriers housed within the unit, making intrinsically safe applications cost-effective without requiring external enclosures and power supplies.
What happens during mains power failure?
The unit features battery backup (2 x 12V 2.1Ah) to continue delivering power during mains supply failure. It’s also possible to turn off outputs under mains fail conditions to preserve battery capacity for critical functions.
How many external circuits can be connected?
The four channels can be individually configured for various input/output modes, allowing up to 8 external circuits to be connected when using combined inputs and outputs (e.g., 4 sector outputs and 4 confirmation inputs).
What ancillary equipment can be connected?
The unit allows connection to ancillary units that cannot be integrated directly onto the SenTRI loop, including external equipment for building control, plant management, and life safety systems requiring separate power supplies.
