Personnel Safety Alarm
The GB Controls Personnel Safety Alarm (PSA) is a high-integrity, fail‑safe system designed to raise an immediate alert if someone is trapped in a walk‑in coldroom or freezer. Supplied as a kit (PSA unit, illuminated coldroom pushbutton with stainless‑steel guard, and external beacon/sounder), it provides a robust, self‑checking safety layer built for harsh environments.
Dual‑channel processing continuously supervises the system and exposes faults via monitored alarm and fault relays. An integrated 95 dB beacon/sounder, 10‑hour battery backup for mains failures, connections for up to 2 coldroom buttons, IP65 housing, and status/alarm LEDs round out a dependable, compliance‑ready package (see BS EN 378‑1:2016 Annex D).
- Fail‑safe, dual‑watchdog design with monitored alarm and fault relays.
- Integrated 95 dB beacon/sounder plus external beacon/sounder with connection monitoring.
- Up to 2 coldroom pushbuttons with supervised wiring (≤30 m).
- 10‑hour battery backup to remain operational during mains failures.
- IP65 enclosure; 85–264 Vac supply; status/alarm LEDs
- Available as kit GBC2000‑PSK
Coldroom Door Open Alarm
The GB Controls Door Open Alarm alerts staff when a coldroom door is left open, helping cut unnecessary energy use in line with Cold Chain Federation benchmarking and reducing risks from temperature rise during prolonged openings.
It offers two configurable time ranges (0–30 or 0–10 minutes), two independent door inputs, and compatibility with NO/NC switches and PNP inductive proximity switches. Door/alarm LEDs provide clear status, while a relay output can drive external systems. An IP65 enclosure, 85–264 Vac supply, low power consumption, and an optional yellow or blue illuminated sounder complete a simple, reliable install.
- Timed alert windows: 0–30 or 0–10 minutes.
- Two independent door switch inputs (NO/NC & PNP proximity supported).
- Relay output on door‑open or alarm with door/alarm LED indication.
- Adjustable alarm intensity with coloured illuminated sounder.
- IP65 enclosure, 85–264 Vac, low power consumption for efficient operation.

Digital Auto Change‑Over Panel Range
The Digital Auto Change‑Over Panel Range automates seamless switching between two independent refrigeration systems on an alternate duty cycle. Change-over is achieved automatically by either a pre-set time, condensing unit fault (if connected), temperature alarm or manually by the door mounted selector switch.
Built to high standards in steel cabinets, these panels support full coldroom control or evaporator-only installations, controlling cooling according to temperature and load balancing logic.
By automatically alternating between systems, these panels not only optimise system efficiency and service intervals but also reduce wear on equipment and offer redundancy. They are especially beneficial in mission‑critical applications where downtime is unacceptable.
