A commercial alarm system done badly costs more than it saves — false-alarm callouts at $200 a pop, monitoring contracts you can't tune, sensors that drop out the week the warranty expires. Done well, it's a reliable, tamper-resistant layer that integrates with your CCTV and access control, alerts the right people through the right channel, and stays in the background until something actually warrants attention. Millar Electrics installs and takes over commercial alarms across Melbourne's eastern suburbs — retail, warehouse, hospitality, multi-tenancy commercial.
Planning coverage on a commercial site
We walk the site, map the perimeter, the entry and exit routes, the after-hours-occupied zones, and the high-value areas, and specify the zone schedule before talking about hardware. Dual-tech sensors (PIR plus microwave) on areas with environmental noise; reed switches on every external door and accessible window; glass-break detectors in shopfront-glazed retail and ground-floor offices; external strobes and sounders where they're an effective deterrent and not a noise complaint waiting to happen. We program the panel with entry and exit delays that fit your actual arming workflow, so the system gets armed every night instead of left unarmed because it's a hassle.
Monitoring and integration
A commercial alarm is only as useful as the response it triggers. Monitored signalling on an IP-primary, 4G-failover path connects to an Australian Grade A1 monitoring centre, which dispatches the agreed response — a phone tree, a patrol, or police via the centre's priority channel. We integrate the panel with your CCTV (so an event tags the footage and switches affected cameras to high-frame-rate recording) and with access control (so a triggered zone disarms cleanly on a valid swipe). The aim is one system from the operator's perspective, not three that share a comms cabinet.
Existing systems and panel takeovers
Most commercial sites already have an alarm — often inherited, often partially documented. We audit the panel, the sensor make and cabling, and any monitoring contract, and re-use what's serviceable. Where the panel is end-of-life or the manufacturer's parts are no longer available we swap the panel and keep the cabling and sensors that pass test. Full rip-and-replace is the exception; documented takeover and tune-up is the rule.
Standards we work to
The mains-side wiring feeding the alarm panel and external strobes is installed to AS/NZS 3000. Sensor and keypad cabling is customer cabling under AS/CA S009, which is why the cabling has to be done by a registered cabler. The intruder alarm system design itself — sensor coverage, entry and exit delays, tamper detection, monitored signalling path — follows AS 2201.1 for intruder alarm systems in premises, and AS 2201.3 for the monitoring-centre interface. Australian-distributed product from Bosch, Inner Range and Paradox meets these as a baseline.
