AquaGuard Power Range
Power and resilience solutions for your residential fire sprinkler pump set — from the dedicated AquaGuard sprinkler fuse box that gives the pump its own protected, separately fused supply, through to standby power that keeps it available when the mains fails. Matched to the AquaGuard pump range, single- and three-phase.
Dedicated supply
AquaGuard sprinkler fuse box
A dedicated, separately fused connection point for the sprinkler pump — designed to meet the electrical requirements of BS 7671 for life-safety systems and BS 9251:2021. Taken as a direct supply ahead of the property consumer unit and run in fire-resistant cabling, it reduces the risk of supply interruption to the pump. Available for both single-phase and three-phase pump sets, and supplied as part of a one-stop range of associated components including rotary isolators and Aico Ei129 smoke-alarm interlink modules.
Single-phase fuse box
For 230V single-phase sprinkler pumps — steel enclosure with a hinged flush lid and 100 A double-pole isolator.
Three-phase fuse box
For 400V three-phase sprinkler pumps — RAL7035 steel enclosure with a 100 A four-pole switch-disconnector and HRC fuses.
Both units are supplied with the 100 A isolator and fuse carrier(s); the three-phase unit includes 3 × HRC aM fuses. Surge-protection ready. Associated components — 20 A rotary isolator (AG-RI-20A) and Aico Ei129 interlink module (AG-EIM) — are available to order. Contact us for pricing and project-specific requirements.
Why it matters
A life-safety pump is only as reliable as its power supply
A residential sprinkler system has to perform on the worst day — which may be the same day the power goes down. Where a project calls for a secondary or standby power supply, the AquaGuard Power Range is designed to keep the pump set energised through a mains interruption and to ride through the high inrush current a motor draws at start-up.
Every solution is matched to the electrical characteristics of the AquaGuard pump it serves, supplied for both 230V single-phase and 400V three-phase sets, and built to integrate with the pump set’s controller, fault contacts and weekly automatic test.
- Sized to the real load of the connected AquaGuard pump set
- 230V single-phase and 400V three-phase options
- Designed to handle motor starting (inrush) current
- Integrates with the controller’s fault and alarm contacts
Sizing
What your set needs from a power supply
The figures below are taken straight from the AquaGuard model data, so a standby supply can be matched to the actual pump it has to run. Starting current — not full-load current — is usually the figure that governs sizing.
| Supply | Pump sets | Motor power | Full-load current | Starting current* |
|---|---|---|---|---|
| 230V 1ph 50Hz | AG75, AG100, AG150, AGV150 (-M), AP75, AP100 | 0.33–2.2 kW | up to approx. 10.5 A | up to approx. 74 A |
| 400V 3ph 50Hz | AG (-T), AGV150–AGV350 | 2.2–11 kW | up to approx. 19.9 A | up to approx. 193 A |
*Direct-on-line starting current. AquaGuard three-phase sets of 3 kW and above are available with a soft starter, which substantially reduces inrush — specify this when sizing a standby supply. Always confirm the exact model and its current draw from the technical data for the set being supplied.
