7 day timer with first-man-in function – 24 V
Camden Door Controls is an ultra compact programmable 7 day timer. It features a large digital display, and 16 flexible easy-to-program on/off schedules. An internal permacell keeps the programs and display readable in the event of a power loss or brownout.
| Low-voltage wiring | Connection count needs review |
|---|---|
| Preparation | Mount the timer using the four mounting screws. Use indoors, protected from moisture, extreme temperatures, shock and vibration. Set the clock and required ON/OFF days and times, then leave the timer in AUTO for programmed operation. Commission the first-man-in pushbutton: the schedule begins only after someone activates it; arrival alone does not unlock the door. |
| Electrical | This exact variant uses 24 V AC/DC. Match the supply to the timer label. The first-man-in relay has a green/green external pushbutton pair and a lock output labelled grey COM, blue NO and orange NC. Its black/white supply pair feeds the assembly; the relay-to-timer leads remain local connections. Select COM with the appropriate NO or NC output for the actual lock logic. The first-man-in relay already has suppression, so the manual says an additional varistor across the timer output is unnecessary. The specification sheet gives conflicting contact ratings; confirm the delivered product rating before selecting a load. Contact ratings do not define supply voltage. Field cable gauge, route and physical run quantities depend on the selected circuits. |
