Fire-Lite PAM-1 — encapsulated multi-voltage SPDT relay module with an energized-coil LED.Manufactured by Air Products & Controls and catalogued by Fire-Lite, the PAM-1 is the general-purpose interposing relay used where a panel output must drive something it cannot switch directly — a door holder, a fan shutdown or a damper. It is fully potted and hangs on its own leads. One SPDT dry form C contact: 10 A at 120 VAC, 7 A at 24 VDC, 250 µA at 5 VDC Coil takes 24 VAC, 24 VDC or 120 VAC; inputs are polarity-sensitive and diode-protected Coil current 20 mA at 24 VDC, 50 mA at 24 VAC and at 120 VAC; pull-in under 1 s Red LED lights whenever the coil is energized Six 12 in. 18 AWG flying leads, with wire nuts, screw and tape 1.50 x 1.20 x 0.77 in.; 32 to 120°F UL S3403, MEA 73-92-E Volume 21, CSFM 7300-1004:101 Check the coil before substituting a sibling: the PAM-2 switches 7 A on a 12 or 24 VDC coil, the PAM-4 spans 12 to 40 VDC and carries no LED, and the PAM-SD runs on 20 to 32 VDC, switches 7 A and adds a seventh lead so a supervised circuit can pass through it.
