Reducing Fire Hazards on Site
Construction environments are dynamic by nature, with constantly shifting conditions, machinery in use, and staff working in separated zones. These factors make reliable alarm coverage essential. Howler's systems—including GOLink, HO alarms, and site alert devices—support coverage for both small-scale and complex layouts.
These units are designed to deploy swiftly, withstand harsh surroundings, and provide clear alerts across site areas.
What Makes HO Alarms Unique
HO alarms are standalone, portable devices suited to non-permanent locations like welfare cabins, tool stations, or isolated zones. Their lack of cabling needs makes installation uncomplicated.
- Sound level: Generally 102 dB at 1 metre
- Optional light: Some models incorporate a strobe light for visibility
- Outdoor-ready: Units often rated IP for weather resistance
These alarms act as a secondary alert system where central alarms may not reach.
Using the Howler Alert Devices
The Site Alert system is ideal for modest projects. It can run as a single unit or be linked via cable with up to 20 devices. When one is activated, all linked alarms respond together.
- Auditory output: Approx. 100 dB at 1 metre
- Visual indicator: Flashing red LED integrated
- Wired connection supports structured placement
Site Alert with Radio Connectivity
For areas where cabling is too difficult, the RF version links up to 30 devices wirelessly. It operates on multiple radio channels and supports an approximate range of 1 km in open spaces.
Mixed installations (wired + RF) can ensure seamless alert howler site alert systems distribution across diverse zones.
GOLink System Overview
GOLink forms a centralised network over radio frequency, allowing a broad array of devices to communicate without physical wiring.
Connecting with External Systems
The Interface Unit enables connections with third-party tools like CCTV, access gates, and autodiallers. When a fire alarm is engaged, signals can be passed across multiple systems instantly.
Medical Alerts via H05
The H05 GOLink model supports first aid notification get more info alongside fire warnings. Pressing the first aid switch sends a pinpointed request to the control panel—without initiating a full alarm unless the setup requires it.
Recommendations for Use
- Plan the layout: Divide your site into logical zones and identify where alerts must be heard or seen.
- Choose connection methods: Use hard-wired systems in structured areas and RF units where cables won’t reach.
- Test routinely: Weekly or monthly checks help catch faults early and confirm battery health.
- Ensure awareness: Train all workers on the alert signals and proper response actions. Post guidance nearby.
FAQs: Technical and Practical Details
- Cable-linked unit capacity?
- Up to 20 Site Alert units on a single 2-core cable loop.
- RF system range?
- Roughly 1 kilometre in clear outdoor conditions, though structural elements may reduce this.
- Is a control panel needed for HO alarms?
- No. These alarms operate entirely on their own.
- Can other systems be connected?
- Yes. Use the GOLink Interface to connect systems such as turnstiles or cameras.
- What’s the alarm cover for?
- To deter false triggers. If tampered with, a warning tone sounds before the actual switch is pressed.
- Are hybrid installations supported?
- Yes. Many projects successfully combine both types, unified through the GOLink network.
- First aid trigger behaviour?
- No. The alert goes only to responders unless your system is set to escalate further.
