Mitigating Fire Risks on Site

Construction environments are dynamic by nature, with frequent changes, machinery in use, and staff working in separated zones. These factors make prompt alarm coverage essential. Howler's systems—including GOLink, HO alarms, and site alert devices—deliver coverage for both small-scale and complex layouts.

These units are engineered to deploy swiftly, withstand harsh surroundings, and provide clear alerts across site areas.

What Makes HO Alarms Unique

HO alarms are battery-powered, portable devices suited to non-permanent locations like welfare cabins, tool stations, or isolated zones. Their lack of cabling needs makes installation rapid.

• 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 Site Alert Systems

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 triggered, 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 unfeasible, 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 distribution across differently structured zones.

GOLink System Overview

GOLink forms a site-wide 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 site management systems like CCTV, access gates, and autodiallers. When a fire alarm is triggered, signals can be passed across multiple systems instantly.

Dual-Switch Units for First Aid

The H05 GOLink model supports first aid notification alongside fire warnings. Pressing the first aid switch sends a pinpointed request to the control panel—without triggering a full alarm unless the setup requires it.

Deploying Howler Alarms Correctly

• 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

How many devices can be linked via cable?

Up to 20 Site Alert units on a single 2-core cable loop.

How far can the wireless system reach?

Roughly 1 kilometre in clear outdoor conditions, though structural elements may reduce this.

Central controller required?

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.

Does a first aid alert evacuate the site?

No. The alert goes only to responders unless your system is set to escalate further.

Summary

Protecting a building site requires effective notification and suitable equipment. The Howler system—through HO, GOLink, and alert models—offers flexibility of construction get more info safety. For detailed product specifications or guidance, visit the Howler section on FireSense.
