DET-6C Pull Station

DET-6C Pull Station

The DET-6-C is a 6-channel EOL transmitter in cottage shell housing. It includes a CAM lock, AC transformer, standby battery, and built-in charger. The unit is housed in a durable cottage shell enclosure suitable for outdoor mounting.

Telegraph codes unique to each of the six zones for Trouble, Alarm, Secure, as well as Tamper and Low Battery are transmitted over 100 mA. circuit using positive non-interfering successive (PNIS) line current detection to avoid clashes between more than one transmitting box. Automatic ground return, a watchdog timer, and a jumper selected internal trouble buzzer assure continued main system operation and operator notification in the event of box failure. A built-in trouble relay output (form C) and the ground and code relay (grounding, opening, or no effect on the 100 mA line) are activated by the watchdog timer ensuring reliable failure detection in the event of malfunction.

Transmission speed is adjustable to match that of mechanical boxes. Unit can be programmed to send any number of rounds (or no rounds) on alarm, trouble, secure and low battery.

Automatic switchover to battery power is performed upon AC power loss with a low battery code transmitted if power is not returned in approximately 60 hours. After transmitting a low battery code, the unit bypasses all input circuits to avoid spurious transmissions of false alarms.

The DET-6C is field programmable with optional EPROM programmer and PC software. A dual 6-zone version (total of 12 zones) is also available.

A master trip module is available for connection to an interior FACP.

Use of lightning protection is recommended for DET-6C and DET12C.
