Fire Alarm Panels

A fire alarm control panel is the central control device that receives information from input devices such as smoke detectors, heat detectors, and manual fire alarm stations. This panel then processes the information to trigger output devices such as bells, horns, and strobes. “Dirty Power” can damage fire alarm control panels, sensors and even output devices, resulting in serious safety issues.

ASCO Power Technologies recommends installing surge protection on any copper wire circuit entering or leaving a fire panel to protect against the damaging effects of lightning strikes and other surges. Typical installation may be close-nipple up to a panel/circuit or hardwired in parallel up to power supply input terminal screws with leads dressed as short as possible.

ASCO Power Technologies also recommends installing surge protection on all data and phone lines to protect fire alarm sys-tems from “backdoor” transients and noise. These transients occur more frequently than high impulse occurrences such as lightning strikes and are usually generated from other equipment operating within a facility.

The ASCO Model 151 (Edco FAS-1) is a multi-stage single pair surge suppressor designed for high exposure applications. This product was specifically designed to meet low voltage protection applications in the fire/security and CCTV industries.

The ASCO Model 171 (Edco PC2-TEL) is a solid state, two-line telephone interface protector module. This unit is designed to protect both phone lines serving commercial fire and security alarm panels. The ASCO Model 171 easily plugs into the ASCO Model PCB1B base.

The ASCO Model 172 (Edco PHC-043) is a rugged series hybrid designed to protect two pairs of wires specifically for alarm and security systems where operating currents can be as high as 5 Amps. The ASCO Model 172easily plugs into the ASCO Model PCB1B base.

The ASCO Model 174 (Edco™ SLCP-043) is a four-wire module designed to protect Signaling Line Circuits (SLC). The device has 0 ohms of resistance and offers line to ground protection. Easily plugs into the ASCO Model PCB1B base.

An ASCO Model 175 (Edco PC642) surge suppressor is recommended for the head and camera ends of PTZ data lines. This is a two-pair (four-wire) module implementing three-stage hybrid technology to protect against multiple surge events, without replacement. The Edco PC642easily plugs into the Edco PCB1B base.

The ASCO Model 180 (Edco LCDP) is designed to conveniently protect eight- wire, low voltage data circuits and employs two RJ-45 jacks for easy installation.

The ASCO Model 237 (PowerSure FAS-120AC) surge suppressor is designed to protect AC distribution panel circuits or 120V power supplies feeding sensitive electronic equipment.

The ASCO Model 252 (Edco HSP-121BT1RU) is a hardwire 3-stage hybrid protector, featuring a 15 amp replaceable fuse, failure indicator and noise filtering. In the rare event of the unit failing, the equipment is removed from the load.
