Specifications
| Manufacturer approvals / certifications | EN54-17:2005/AC:2007; EN54-18:2005/AC:2007; IACS E10. Printed 2531-CPR-232.1707 / DoP CN-1707; current validity unknown. |
|---|---|
| Manufacturer Article Number | 023261 |
| Compatible Control Systems | NSAC-1; TERRA FIRE; TERRA ONE. |
| Loop Voltage | 34 VDC nominal; 20–38 VDC working. |
| Loop Current | 0.3 mA working; 10 mA alarm. |
| External Power | 24 VDC ±20%; 50 mA input (about 15 mA per relay). Separate supply required when relays are used. |
| Detector / Switch Supply | IN1/IN2: 12–15 V DC supplied from the loop. |
| Inputs / Relay Outputs | 2 inputs; 3 programmable relay outputs. Two relay outputs can supervise an external control cable. |
| Relay Contact Load | Maximum 24–48 VDC / 1.0 A. |
| Address / Function Switches | 8-way address DIP; 6-way function DIP. |
| Enclosure / Environment | IP65; PC/ABS; −10 to +55 °C; 0–95% RH. |
| Weight | 500 g ±5%. |
| Printed Standards / Safety Scope | EN54-17:2005/AC:2007; EN54-18:2005/AC:2007; IACS E10. Printed 2531-CPR-232.1707 / DoP CN-1707; current validity unknown. |
| Fire Mode / Device Selection | DIP 6 ON. DIP 1–3: 0 Detector, 1 Smoke, 2 Heat, 3 Manual call point, 4 IS, 5 Fire, 6 Sprinkler, 7 Flame. Normally use NS-AIN1 for intrinsically safe devices. |
| Fire-mode Power Supervision | External 24 V supply is NOT supervised in fire mode. |
| Conventional Detector Interface | Remote LED indication. If the detector lacks internal Ri, add about 330 Ω in series to distinguish fire from short-circuit fault. |
| External Fire Interface | IN1 fire closing contact; IN2 pre-alarm closed contact / external fault open circuit. OUT1 reset pulse about 3 s; OUT2/3 programmable. |
| Terra One Limitation | Pre-alarm is unavailable in the Terra One single-loop panel. |
| Sprinkler Interface | Flow alarm delayed about 15 s to reject pressure shocks; IN2 section valve supervised for fully open position. |
| I/o Mode | DIP 6 OFF. 2 digital inputs; 2 external cable supervisions; 3 relay outputs; external 24 V supervision. |
| I/o External Supply / Suppression | External 24 V is needed for relay activation and IN3/4 supervision. Fit a switch-off diode to external relays/contactors to prevent voltage spikes. |
| Safe / Unsafe Inputs | Safe: IN1 confirms safe position; Unsafe: IN2 confirms unsafe position. |
| Failsafe / Watchdog | Failsafe opens relays on power loss. Watchdog requires RKS06 and holds relay position for a period after loop power loss. |
| Auto Function | Opens relays for fire, fault, or disabled-then-fire devices within ±3 addresses. |
| Mode 11 Special Action | The starred exception automatically CLOSES relays if any disabled device on the same loop enters fire alarm. |
| I/o Mode Matrix: 0–5 | 0 General I/O; 1 bell control (RKS05 only); 2 Safe; 3 Safe+Failsafe; 4 Failsafe+Auto; 5 Safe+Failsafe+Auto. |
| I/o Mode Matrix: 6–9 | 6 Safe+Failsafe+Watchdog+Auto; 7 Failsafe+Watchdog+Auto; 8 Safe+Unsafe; 9 Safe+Unsafe+Failsafe. |
| I/o Mode Matrix: 10–16 | 10 Failsafe+Watchdog; 11 Failsafe+Watchdog+Auto*; 12 Failsafe; 16 Local timer. Modes 6,7,10,11 require RKS06. |
| Dsci Wiring Recommendation | Interconnect/crossconnect the positive leads to one terminal using a jumper or similar. |
| Original Installation Drawings | All 8 original pages retained: terminal numbers, enclosure/mounting dimensions, DIP diagrams and connection examples. Refer to original PDF before installation. |
