Summary
The Hochiki CHQ-SIM is a single input module built for jobs where space is at a premium and a full-size interface module simply won’t fit. Its compact ACS case and flying leads let you add a monitored input onto an ESP loop in awkward cavities, tight risers or cramped equipment cabinets without compromising on wiring quality.

For you, that means fewer compromises on site: you can bring a monitored contact onto the loop exactly where it’s needed, rather than routing extra cable back to a bulkier enclosure. It also cuts down the time spent fighting for space behind a ceiling tile or inside a small cupboard.
The CHQ-SIM delivers this through a small footprint (just 65 x 42 x 15mm), a choice of flying leads or a wiring terminal block, and an onboard programming connector for addressing with the TCH-B200 hand held programmer and a PL-3 lead.
Features
- Compact footprint – fits into enclosures and cavities where a full-size module won’t go
- Flying leads and terminal block – choose the wiring method that suits the install
- Single monitored input with EOL resistor – ready to detect open circuit, normal, activation and short circuit states straight out of the box
- Low quiescent current – typically 150 μA at 41V, so it loads the loop lightly
- Hand held programmer addressing – set the address via the onboard connector and a PL-3 lead, no separate programming rig needed
- LPCB and VdS approved – recognised for use on protected systems
FAQ
Use a TCH-B200 hand held programmer connected via a PL-3 lead to the onboard programming connector. There’s no need to remove the module from its mounting position to set or check the address. No. Hochiki states that the input/output devices on the CHQ-SIM must not be operated with fire protection products (type 1 devices), so it’s intended for monitored input signals only, not direct connection to detection or notification devices. The CHQ-SIM has both flying leads and a wiring terminal block for the loop connection, so you can pick whichever suits your containment and termination method on site. It distinguishes open circuit (greater than 100 KΩ), normal state (100 KΩ, EOL resistor provided), input activation (470 Ω, EOL resistor provided) and short circuit (50 Ω), covering the full monitored input range without adding separate resistors. It operates from 17 to 41 VDC drawn from the ESP loop, with a typical quiescent/alarm current of 150 μA at 41V, so loop loading calculations should be straightforward. Operating range is -10°C to +50°C (storage -30°C to +60°C) with a maximum humidity of 95% RH non-condensing at 40°C, suiting most internal plant rooms and risers. For anything outside that range, check with the manufacturer before specifying.How do I address the CHQ-SIM on site?
