Specifications
- Input:
- 120VAC, 60Hz
- 3.5 amp
- ACM8CB board is rated at 10A
- PS input options:
- a) (1) common power input for ACMBCB and lock power b) (2) isolated power inputs-(1) to power the ACM8CB and (1) for lock power (external power supply is re-quired) Current is determined by the power supply connected, not to exceed a maximum of 1 0A total (8) Access Control System trigger inputs
- Input options:
- (8) normally open (NO) inputs or (8) open collector inputs or any combination of the above 12VDC or 24VDC outputs @ 4A supply current. Power-limited outputs
- Output:
- (8) independently trigger control outputs (8) Fail-Safe filtered power output or (8) Fail-Secure filtered power outputs or any combo of the above (8) unswitched filtered auxiliary power outputs (outputs are rated @ 2A)
- Output Options:
- Over voltage protection & short circuit and thermal overload protection
- Fire Alarm Disconnect:
- (latching or non-latching) is individually selectable for any or all of the eight (8) outputs
- FA Disconnect Options:
- Normally open (NO) or normally closed (NC) dry contact Input
- Polarity reversal input from FACP signaling circuit
- Alarm output relay indicates that FACP input is triggered (form “C” contact rated@ lA 28VDC (not UL)
- Supervision:
- AC fail supervision (form “C” contacts)
- Battery fail & presence supervision (form “C” contacts)
- Low Power Shutdown:
- Shuts down DC output terminals if battery voltage drops below 71-73% for 12V units and 70-75% for 24V units (depending on the power supply)
- Prevents deep battery discharge
- Visual Indicators:
- Red LEDs indicate outputs are triggered (relays energized)
- Green LED indicates FACP disconnect is triggered
- Battery backup: (batteries sold separately)
- Built-In charger for sealed lead acid or gel type batteries (batteries sold separately)
- Automatic switch over to stand-by battery when AC fails, no interruption instantaneous switch over
- Zero voltage drop when unit switches over to battery backup (AC failure condition)
- BTU/Hr.:
- 12VDC: 25 BTU/Hr.
- 24VDC: SO BTU/Hr.
