Apollo Intelligent Mains Switching Input/Output Unit, Fire Alarm Interface SA4700-103APO
About this product
The Apollo SA4700-103APO is a fire alarm interface for monitoring contacts and switching mains from an addressable loop. It suits installers linking a fire system to other equipment. It has two input channels and a relay rated 5 A at 30 V dc or 250 V ac, with XP95, Discovery and CoreProtocol compatibility.
Key features
- Switches mains directly – a voltage free change over relay output capable of switching mains
- Watches two things at once – two input channels
- Acts if the loop is lost – Failsafe mode activates the relay on loss of loop or protocol loss
- Shows what is happening – status LEDs for relay, polling, isolator and inputs
- Quicker to wire – improved design for ease of wiring meaning faster installation
- More options on CoreProtocol – nine pre-configured modes and earth fault monitoring, on CoreProtocol enabled systems only
For installers
- Power: loop powered, 17–35 V dc. Quiescent current 700 µA, max current with LEDs on 5.2 mA.
- Mounting: surface with the supplied back-box, or flush using a UK double gang back-box of minimum depth 30mm. 60 mm height x 150 mm width x 90 mm depth.
- Cabling: relay contact rating 5 A at 30 V dc or 250 V ac. Inputs use a 20k end-of-line resistor and 1k input trigger resistor.
- Compatibility: XP95, Discovery and CoreProtocol compatible, fire control panel dependant. It behaves as XP95 on XP95/Discovery and as Soteria on CoreProtocol.
- Standards: EN 54-17, EN 54-18, CPR, LPCB, VdS, BOSEC, SBSC, FG. IP54.
Frequently asked questions
Can it switch mains voltage?
Yes. The relay contacts are rated 5 A at 30 V dc or 250 V ac, and they are voltage free.
What happens if the loop fails?
In Failsafe mode the relay activates without being commanded by the control panel, on loss of loop or protocol loss. Failsafe mode is selected with a DIL switch.
Does it work on XP95 and Discovery panels?
Yes, behaving as an XP95 device, depending on the fire control panel. Several features, including the controllable isolator, are for CoreProtocol enabled systems only.
Is a back box included?
Yes. Surface mounting uses the supplied back-box. Flush mounting needs a UK double gang back-box of minimum depth 30mm.
How much loop load does it add?
It has an Equivalent Detector Load of 2. The maximum load for a node is an EDL of 20.
