Security Systems for Offices, Warehouses and Plants

On a commercial site an alarm answers a management question rather than a domestic one. There are people with financial liability, keys to the till and the trading floor, a night shift, cleaners and contractors — and the question after an incident is not whether someone broke in but who disarmed the site at 04:12 and on what grounds. So for an office, a sales area, a warehouse or a workshop we design a system with three mandatory properties: rights separated between departments, a log that can be used as documentation, and a written response procedure known to the guards and to the staff alike.

Such sites rest on wired and hybrid loops. Cable does not depend on batteries or radio interference, and across thousands of square metres, among metal racking and running machinery, that argument decides the matter. Where documentation is submitted to supervisory authorities we use Bolid devices: the Signal-20P panel on compact sites and the S2000 line with addressable expanders where there are many loops and every detector must be tied to a specific room. A hybrid scheme earns its place during expansion: the trunk stays wired, while an annexe or a newly rented block is picked up by a radio expander without opening up the finishes.

Partitions describe a structure of responsibility, not convenience. Accounting, the server room, the finished-goods store and the trading floor become separate partitions, each with its own list of who may arm and disarm it. A storekeeper cannot disarm the cash zone, a salesperson cannot open the warehouse, and a shift supervisor reaches the common areas but not the safe room. With shift work this immediately answers the contested question: the partition was armed, a specific code disarmed it at a specific minute, and a specific crew took over the shift.

A link to a monitoring station turns an alarm into a dispatch. The chain looks like this: the device passes the signal to a private security company's station over two independent channels, the operator opens the site record and sends the nearest crew, the usual arrival target within the city is five to ten minutes, and the crew leader inspects the perimeter and the entry points and writes an inspection statement. The client's responsible representative is called at the same moment as the dispatch, so that the premises are opened with the crew present rather than alone. The contract with the security company is signed by the site owner; our part is to prepare the device technically, program the transmission channels and take part in the scheduled link tests.

Tying the alarm to CCTV and access control removes the biggest cost item — false dispatches. Every device event marks the matching fragment of the archive, and the operator sees within a minute what it was: a draught moving a banner, or a person in the room. On the access side the logic runs the other way: the last employee taps a card on the way out and the site arms itself, while an attempt to open a door with a card inside an armed zone is blocked until it is disarmed. On a site of several buildings all of this comes together at one guard post with a shared plan and a single event list.

A panic button at the till and in the manager's office is installed together with a written procedure, otherwise it is useless. Pressing it must be covert and silent on site: the intruder must not realise that help has been called, so the fixed button is mounted under the counter and the staff with financial liability get wearable fobs. The procedure sets out who presses it, what the rest of the staff do — no arguing, no chasing, step away from the till — whom the manager calls, and how the crew tells a real call from an accidental one, by a code word on the call back. We brief the staff at handover and again on the client's request.

The event log is not a service line in an interface but a document used when an incident is examined. The device records every arming and disarming with the user code, the partition number and the time to the second, along with detector tamper openings, loop faults and power losses. In a shortfall case or a dispute with a tenant, a selection for the required period is exported from the log and matched against card passages and the video archive — that is usually enough to take the emotion out of the conversation. The log is kept on the device itself and on the site server, with the depth set to the security department's requirements.

A working system rests on a routine. Under a service contract we check the detection zones, loop resistance, battery capacity, the passage of a test signal to the monitoring station and the currency of the user list once a quarter: codes of people who have left are deleted, which is the most common hole. We service what we installed ourselves and equipment we supplied; for systems installed earlier by others we run an audit and an upgrade, after which the site goes onto scheduled maintenance. We design and install across Uzbekistan, take enquiries on weekdays from 9:00 to 18:00, and reply within the working day. For an apartment, a house or a country cottage the set of tasks is different and simpler — that is what the page on residential burglar alarms is for.
