Summary
The EMS SmartCell EMS‑41‑0202‑0001‑WZ lets you add supervised inputs and volt-free outputs to a fire system without pulling a single extra cable, making it the go-to choice for retrofits and awkward sites where conventional wiring is impractical or too disruptive.

For you, that means faster first-fix, fewer containment runs to price and install, and a way to extend coverage into areas that would otherwise blow the budget on cable and labour. It also opens up contract scope on jobs where the client wants extra monitored points added after the main system is already wired in.
It delivers this through dual-band 868 MHz wireless communication with the iWZM, connecting into both addressable and conventional fire systems. Three CR123A lithium cells give up to ten years’ service life with built-in battery health monitoring, so you’re not back on site swapping batteries every year, and the device carries EN54-18 and EN54-25 certification for use on fire detection and alarm installations.
Features
- Resistor monitored inputs – detects open and short circuit faults on the supervised wiring, so you can rely on the input status
- Volt-free changeover outputs – rated 1A at 30VDC to drive ancillary equipment such as sounders, dampers or door releases
- Ten-year battery life – three CR123A lithium cells cut the number of return visits needed for battery replacement
- Battery health monitoring – flags a failing battery before it takes the device offline
- Removable 180° opening door with clip-in hinges – gives full access for wiring and commissioning without removing the enclosure from the wall
- Multiple M20 cable entry knock-outs with drill guides – flexible cable routing on site without guesswork
- Dual band 868 MHz wireless link to iWZM – integrates into both addressable and conventional fire panels
- Up to 1400m clear line of sight range – gives you flexibility in siting the device away from the panel
- UL94 5VB fire-rated PC/ABS enclosure – suited to installation within fire-related systems
FAQ
The EMS‑41‑0202‑0001‑WZ communicates wirelessly with the iWZM, which bridges it into addressable and conventional fire systems. Check with EMS or your Huvo contact that your specific panel type is supported by the iWZM before specifying it on a job. It runs on three 3V CR123A lithium manganese dioxide cells with a capacity of at least 1550mAh, giving up to ten years of service under normal usage. EMS has certified the device with Duracell DL123A and CR123A Intense, and Panasonic CR123A PA/BD cells, so stick to these when replacing batteries. No. It’s rated IP65 for indoor use only, so it isn’t suitable for direct exposure to weather. Choose an indoor location, even if it’s an unheated cupboard or riser. The two inputs are resistor monitored, meaning end-of-line resistors are used to detect open and short circuit faults on the wiring. The datasheet doesn’t specify resistor values, so confirm these against the full installation manual before wiring. EMS quotes up to 1400m on a clear line of sight, but this is a maximum figure with no obstructions between the device and the iWZM. Walls, floors and equipment will reduce that in practice, so always survey the site and check signal strength during commissioning rather than relying on the headline figure. Yes, it uses the X5 signalling protocol over dual band 868 MHz and communicates specifically with the iWZM rather than talking directly to a panel. Factor the iWZM into your design and pricing alongside this device.Will this work with my existing fire panel?
